MINI-FAQ Gspot 2.5

Short Answer:  There is a plan to correct this.
Long Answer:  Unlike AVI files, MPEG is a "streaming" file format; it's designed so players can decode it starting from an arbitrary spot. As such, it has no "header" with info about the file in its entirety, as an AVI file does. This means that the only way to obtain accurate information on most characteristics, including simple things like the number of frames, is to scan the entire file, which can take minutes. Unfortunately, this conflicts with a design goal of GSpot: to be responsive and nearly instantaneous in providing results. This has been accomplished by GSpot in the past by reading only the first 1 MB or so of any file, regardless of size. That's plenty for AVI, as most of the information is summarized in the very beginning.
Things got more complicated with the inclusion of MPEG support in GSpot 2.5+. A number of "tricks" are now used - for example GSpot will now read both the very beginning and the very end of the file, and then attempt to subtract the timestamps that are available in, for example, an MPEG system stream. Nonetheless, it often resorts to estimation. While these estimates are fine for many applications, for many they are not. One user, for example, sent an email describing how he used GSpot in batch mode to create scripts which were in turn used to trim MPEG files right at the last frame (or something like that). To his dismay, he discovered many of his files were being cut at the wrong spot.
So, getting to the point here, a functional addition to GSpot is in the works: it will continue to analyze large stream files "in the background", using a separate low-priority thread. The idea is that GSpot will give instant results, with some fields estimated, just as it does now. It will then continue improving those values - with some indication of when it's "done" for those that need to know. Those that don't care can ignore this, as it will be fully responsive and all functionality will be immediately available as it is now. If the function chosen is to open a new file, the scan is simply aborted; otherwise it quietly continues. Batch / export users will be given a choice of "fast mode" or "accurate mode" to suit their needs.
No estimate yet on when this will be done, but it's in the works.

It says "codec is installed", but doesn't show what codec - how can I see that info, like I can with v2.21?

Actually, as soon as you load a file it runs a instantaneous "#1" pseudo-render (see below), though it does that under the hood so as not to bother the casual user with technical mumbo-jumbo. But therein lies your answer: If the automatic "1" press is able come up with at least one theoretically working graph, it will say "codec is installed"; conversely whenever it says "codec is installed", it means that pressing "1" is guaranteed to have at least one good result. So "pressing #1 and looking at that result" is how you find out what it had in mind when it said "codec(s) are installed". As of v2.52 b1, you can also right click on the codecs to obtain additional details.

What do the #1, #2, and #3 buttons do?

The MS ("Microsoft") render button "1" is equivalent to the old v2.21 render (although it's currently less informative insofar as you can't get the "details" on what's shown, but that should be corrected in a future update). MS button "2" will take that "graph", as Microsoft calls it, and actually play it in the monitor window (assuming step 1 was successful).
The GSpot Video "1" button attempts to create one or more "theoretical" graphs - it does this quickly, in memory, by "logic" only, with no additional access to the codecs involved (i.e. no access beyond the info gained when GSpot started). This is much faster and far less likely to crash on a problem system (one with bad codecs) than the Microsoft render. That's because the MS algorithm is a "trial and error" system which just keeps loading codecs, hooking them together, and seeing if it says it will play. On the downside, the GSpot "1" button isn't as accurate - it may come up with some results that don't "play" when you actually try them (this is due to codecs claiming they accept all these formats that they really don't - something which can be changed with GSpot's "edit mediatypes" function - but that's another story). Also note that the GSpot algorithm is quite rudimentary at this current beta stage, but I'm hoping to improve it as time goes on.
Now, even though this "1" is not as accurate as really trying it, as I mentioned, it's still better for the "codec is / is not installed" status than the GSpot v2.21 system, which just checked for the existence of a codec matching a certain format. It's more accurate because it builds the whole "graph" - if only theoretically. For example, if you had a DivX movie file and did have a DivX codec but had no "avi splitter" to feed it, v2.21 would say "installed" but v2.5 would say "not installed". That's more accurate since the file can not be played under those conditions. It's not a very realistic example since everyone has (or should have) "AVI Splitter" since windows comes with it, but you get the idea.
Anyway, button "2" actually loads and "connects" the codec graphs created in "1" to see if the result says it will actually play - now you have one or more actual "connected" graphs, similar to one created by the MS render "1" button. Lastly, the "3" button ACTUALLY plays the file in the monitor window, like MS #2 (it's really not as confusing as it sounds!). It's actually quite rare for a file not to play once there is a successfully connected graph, but it can happen (or it may "play", but be all in shades of purple and green). So the ultimate test is seeing it with your own eyes like that.
Note that the #3 button plays the first successful one listed if there are more than one. But you can selectively play the one you want using a right click option to see if one works "better" than another, or better than the Microsoft solution. If it does, you can control Microsoft's algorithm using GSpot's "merit set" or "edit mediatypes" functions, but again, that's another story. Oh yeah: regarding everything stated above about GSpot Video buttons "1", "2" and "3": Audio is the exact same deal. I keep them separate as it's a much more useful diagnostic that way. The MS render, by contrast, is an "all-in one" deal.

    About the K-Lite Codec Pack

K-Lite Codec Pack is a collection of DirectShow filters, VFW/ACM codecs, and tools. Codecs and DirectShow filters are needed for encoding and decoding audio and video formats. The K-Lite Codec Pack is designed as a user-friendly solution for playing all your audio and movie files. With the K-Lite Codec Pack you should be able to play all the popular audio and video formats and even several less common formats.

The K-Lite Codec Pack has a couple of major advantages compared to other codec packs:

• It is updated frequently. So it is always up-to-date with the newest and/or best components.
• All components have been carefully selected for specific purposes. It is not just a random bunch of stuff thrown together.
• It is very user-friendly and easy to use.
• The installation is fully customizable, meaning that you are able to install just those components that you really want.
• The customization abilities even go beyond the component level. Some components are able to handle multiple formats. You can specify exactly which components should handle which formats. The pack can thus be fully tweaked to your own specific needs and preferences.
• Uninstallation removes everything that was installed by the pack. Including all registry keys.
• It is extremely easy to make a fully customized unattended installation with the integrated wizard.
• It does not contain any bad, buggy or unstable codecs.
• It tries to avoid potential conflicts with other codecs installed on your computer. The installation is able to detect and remove over 100 different codec and filter packs.
• The pack is able to detect broken codecs and filters on your system, and helps you to remove them.
• It is a very complete package, containing everything you need to play your movies.
• This pack has a huge user base. This means that problems are found and resolved quickly.
• There are different variants of the pack. From very small to large.
• The pack is suitable for both novice and expert users.

    Variants

There are five variants of the K-Lite Codec Pack:

The basic variant contains everything you need to play all the common video file formats. Such as AVI, MKV, MP4, OGM, and FLV. This pack is for those who like a small no-nonsense pack.

The standard variant contains some additional features compared to the basic variant. It contains Media Player Classic, which is an excellent player for video files. It also has (better) support for playback of DVDs. This pack is recommended for the average user.

The full variant has many additional features. It supports playback of several (lossless) audio formats. It contains VFW/ACM codecs that can be used f-or encoding. It has playback support for a few legacy audio and video formats. This package is suitable for power users.

The corporate variant is a special version for use in a corporate environment. It is similar to the full variant, minus a few items, but almost just as powerful. It has a strong focus on open source software.

The mega variant has the same contents as the full variant, but additionally contains Real Alternative.

The K-Lite Codec Pack works on Windows 2000/XP/2003/Vista.

ältere Changelogs-KLite-Codecpack

Release Notes:
The K-Lite Codec Pack is a free collection of codecs and related tools. Codec is short for Compressor-decompressor. Codecs are needed for encoding and decoding (playing) audio and video. The very user-friendly installation is fully customizable, which means that you can install only those components that you want.
There are three versions of the K-Lite Codec Pack: The Basic version, who fits on a single floppy disk, contains only the most essential codecs and related tools. The Standard version contains everything what is needed to play all the commonly used formats. The Full version contains even more codecs and also has encoding support.
It is highly recommended to uninstall all existing codec related software before installing. This way your system stays clean and potential problems will be avoided.

• Bitrate Calculator
  This can be used to calculate the bitrate to use when encoding a movie.

DivX 3.11 ist eigentlich eine Modifikation des Microsoft MPEG4 Encoder/Decoder. Er wurde programmiert, da Microsoft seinen Code künstlich limitierte um nicht korrekt mit dem "AVI wrapper" zu arbeiten. Microsoft wollte damit den Nutzen auf das eigene ASF-Format beschränken, welches nun unter dem Namen "Windows Media Video" bekannt ist.
Der einzige Grund, warum man überhaupt DivX 3.11 installieren sollte ist, wenn man Windows XP als Betriebssystem nutzt. Das DivX 3.11-Installationsprogramm fügt dem System ebenfalls einen MP3 Encoder/Decoder hinzu und ersetzt damit die schlechte Version, die Microsoft mit Windows XP ausliefert. Die eigentliche Installation von DivX 3.11 ist harmlos und sollte keine Konflikte mit dem restlichen System verursachen.

• DivX 4.xx und DivX 5.xx, sowie neu DivX 6.xx sind eine komplette Neuprogrammierung der sog. "MPEG4 Simple Profile-" und "MPEG4 Advanced Simple Profile Encoder/Decoder" (MPEG4-Part2). Diese Versionen sind eigenständige Produkte, und keine Modifikationen mehr. Sie können ebenfalls DivX 3.11-Inhalte dekodieren und ersetzen bei Ihrer Installation einen bereits verfügbaren Divx 3.11-Decoder. Dieses Verhalten kann allerdings geändert werden durch Anpassen des entsprechenden "Merit" (hierzu mehr im entsprechenden Teil - siehe auch Radlight).
  Diese Software muss nicht installiert werden, wenn der Filter "FFDShow" zum Einsatz kommen soll.

Einzelne Filter installieren

Nicht alle Komponenten (DirectShow Filter) aus dieser Anleitung kommen mit einem Installationsprogramm. Einige von Ihnen sind lediglich ein komprimiertes Archiv (normalerweise als ZIP- oder RAR-Datei) und enthalten entweder eine ".AX" oder ".DLL"-Datei. Um diese Komponenten zu installieren muss das Archiv in ein beliebiges Verzeichnis entpackt werden (ein guter Ansatz ist, sich ein Verzeichnis "Filter" innerhalb des eigenen "C:\Programme\"-Ordners anzulegen). Nach dem Entpacken müssen diese Filter im System registriert werden. Dazu dient das Programm "REGSVR32.EXE", welches jedem Windows-System beiliegt.
Um zum Beispiel den Filter "neuerfilter.ax", der in das Verzeichnis "C:\Programme\Filter\" entpackt wurde, zu registrieren, öffnet man das Windows-Startmenü, klickt dort auf "Ausführen..." und gibt folgende Zeile ein:
regsvr32.exe c:\programme\filter\neuerfilter.ax
Wenn der Pfad oder Dateiname des Filters ein Leerzeichen enthält, dann muss der zweite Teil des Befehls in Anführungszeichen gesetzt werden:
regsvr32.exe "c:\meine programme\filter\neuerfilter.ax"
Daraufhin sollte eine Nachricht "DLLRegisterServer in neuerfilter.ax succeeded" auf dem Bildschirm erscheinen, die besagt, dass eben dieser Filter nun im System registriert ist.

Tip

All installers are customizable, meaning that during the installation process you can select which components should be installed and which ones should not be installed. For full and mega, there even are several pre-defined profiles that you can use as a starting point for your customization.
You can for example install both the K-Lite Mega Codec Pack and the new beta of QuickTime Alternative. [1] Uninstall your current package(s) [2] Install the K-Lite Mega Codec Pack. Deselect the QT Alternative components in the installer. [3] Install QT Alternative.

Tip

Here is a tip for all those people that want to play those QuickTime HD clips (the ones that use the new H.264 codec). You can play them with the K-Lite Mega Codec Pack. Download the files to your harddrive. Then simply rename the files from .mov to .mp4. The required codecs are: Haali's MP4 splitter and ffdshow (for H.264 and AAC). Playback will be better than with the new QuickTime 7!

FFDShow ist ein Multi-Format Dekodier-Filter mit vielen "Post Processing"-Möglichkeiten (Nachbearbeitung des auszugebenden Bildes). Er ermöglicht die Dekodierung folgender Formate: DivX (3.11/4.xx/5.xx), XviD, Microsoft MPEG4, einige der WMV-Formate, Theora, Motion JPEG, HuffYUV. Weitere Formate werden mehr oder weniger regelmäßig hinzugefügt. Ausserdem dient er als "Post Processing"-Filter für die angegebenen Formate sowie für Roh-Video (bspw. erzeugt durch DVD-Dekoder). Damit kann er die Bildqualität verbessern oder auch ein De-Interlacing (Interlacing: Zeilensprungverfahren z.B. bei Fernsehbildern) durchführen. FFDShow nimmt mit jeder Version an Funktionen zu. Er ist momentan der empfehlenswerteste Filter für die Wiedergabe von DivX/XviD, und - für alle fortgeschrittenen Nutzer - er kann die Wiedergabe von DVD verbessern. Für die ausgefalleneren Funktion ist natürlich eine hohe Prozessor-Leistung von Nöten.
FFDShow ist sehr "Konflikt-freundlich". Man kann ihm sagen, welche Formate er spielen soll und überschreibt damit die bisherige Dekoder-Zuordnung für das entsprechende Format - das alles auf sehr saubere Art.

Features:
- Fast video decompression using optimized code for MMX (MultiMedia eXtensions), SSE (Streaming SIMD (Single Instruction Multiple Data) Extensions), SSE2, SSE3 on Intel Pentium processors and 3DNow! on AMD (Advanced Micro Devices) Athlon processors
- Support for a lot of different codecs
- Image postprocessing for higher playback quality
- Automatic quality control: it reduces the postprocessing level when the CPU (Central Processing Unit) load is high
- Hue, saturation and luminance correction
- Experimental sharpening filter
- Presets
- Support for various subtitle formats
- FFDShow is completely free and Open Source under the restrictions of the GPL (General Public License)

Zu den verschiedenen Audio-&Videocodecs können Sie festlegen, ob der Original Directshow-Filter bzw. ersatzweise ffdshow mit seinen libavcodec (oder anderen einen anderen integrierten Filter wie z.B. libmpeg2 - gleiche Bibliothek wie der Player "VLC") das Video dekodiert. Gleichzeitig sind viele Filteroptionen zur Bildmanipulation (aber auch für Audio) anwendbar. Profis haben sogar ein Mittel zur Pre- und Postprocessing-Optimierung! (Bzw. Abspieloptimierung bei fehlerhaften Dateien).

ffdshow ist ein Open Source DirectShow-Filter für Windows zur Wiedergabe von Video- und Audiodaten.
Mit Hilfe des libavcodec, Bestandteil des FFmpeg-Projektes, sowie einer Reihe anderer ebenfalls quelloffener Decoder (XviD, libmpeg2, mp3lib, etc.) decodiert das Programm alle wichtigen Video- und Audioformate, einschließlich MPEG-2, MPEG-4 (DivX, XviD, etc.) und AVC/H.264. So ist es nicht nötig zur Wiedergabe dieser Multimediaformate separate Codecs zu installieren. Des weiteren beherrscht ffdshow viele Methoden um die Ausgabe der Video- bzw. Audiodaten zu beeinflussen. So kann die Software beispielsweise vorhandene Untertitel verarbeiten oder verschiedene Filter setzen um die visuelle und/oder klangliche Qualität des Films zu verbessern. Darüber hinaus, kann ffdshow auch als Video-Encoder für diverse Formate (z.B. DivX 3) eingesetzt werden. Die in ffdshow enthaltenen Video-Filter können dank der mitgelieferten Plugins in den beliebten Video-Editoren VirtualDub und AviSynth genutzt werden. Es ist auch möglich DScaler Filter in ffdshow zu benutzen.

Das deinstallieren von Codecs ist eigentlich nicht nötig, denn es
lässt sich (leider nicht so einfach) einstellen, welche decoder
filter DirectShow für welchen Codec bevorzugt. Bei der Installation
eines Decoder/Encoders setzt dieser sich naturgemäß an erster Stelle,
weshalb das wilde Hin- und Herinstallieren das Video-System von
Windows ganz schön durcheinander bringen kann. So ist es nicht weiter
ungewöhmlich mehrere (drei bis fünf oder mehr) Decoder für MPEG-Audio
im System zu haben, von denen aber eigentlich immer nur einer
bevorzgt wird (es sei denn Player oder Demux-Filter bevorzugen einen
anderen, im Falle von Playern, eventuell sogar den eigenen internen,
der sonst nicht über DirectShow anderen Programmen zur Verfügung
steht. Beispiel: VideoLan oder Media Player Classic). Ein gutes Tool,
um sich das ganze DirectShow Gebilde einmal grafisch anzuschauen, ist

so einzeln zu bekommen, allerdings nicht direkt von MS soweit ich
weiß. Goggle hilft ;)

ffdshow bietet zum Glück die Möglichkeit, die Prioritäten für
bestimmte Codecs zu ändern, man braucht also kein extra Helfer-Tool
oder muß auch nicht in der Registry rumtüfteln. Wenn du Probleme mit
der Dekodierung eines Codecs hast, dann kannst du ffdshow
veranlassen, den problematischen Codec nicht mehr anzutasten unter
"Start menu->Programs->ffdshow->Video decoder configuration", dann
"Codecs->DivX 3" auf einen (hoffentlich vorhandenen) Alterntiv-Filter
setzen.

Eine andere Möglichkeit wäre die neuesten alphas von ffdshow zu
benutzen, die sind teilweise der letzten beta und dem letzten stable

die DivX3 besser als die Version, die du im Moment benutzt. Ich nutze

Tip: How to Change the Selected Codec with RadLight Filter Manager

GraphEdit is a visual tool for building and testing filter graphs. It is provided as an executable with the DirectX SDK. With GraphEdit, you can quickly build and test filter graphs to see if they function as you expect. You can even view a filter graph created by an application running in another process.
Filters are displayed as boxes, with a text caption showing the name of the filter. Pins appear as small squares along the edge of the filter. Input pins are on the left, output pins on the right. A pin connection appears as an arrow connecting the output pin to the input pin.
GraphEdit uses a custom persistence format. This format is not supported for application use, but it is helpful for testing and debugging your application.
Note  The GraphEdit source code is not provided, and you may not redistribute the executable. Daher Download z.B. bei http://www.dvd.box.sk (über "search" graphedit suchen/downloaden)

AAC

• LC-AAC: Dem normalen AAC, auch "Low Complexity" Profil genannt, kurz LC-AAC. Es ist für mittlere und hohe Bitraten konzipiert, also 128 kbps und aufwärts, dort ist es mit LAME-MP3s gleichwertig, hat aber hörbare Schwächen gegenüber Ogg Vorbis und MPC. Die besten Encoder stammen momentan von Ahead (Nero) und Apple (QuickTime/iTunes).
• HE-AAC: AAC plus SBR, eine Technologie die schon beim gefloppten MP3Pro zum Einsatz kam. Auch AACplus oder HE-AAC genannt ("High Efficiency" Profil). Wurde für niedrige Bitraten, also unterhalb von 96 kbps entwickelt und ist für portable Player, Streaming oder einfach Nutzer mit nicht allzugroßen Qualitätsansprüchen sehr interessant, da es dort wesentlich besser als MP3 ist und laut Hörtests sogar der beste Encoder überhaupt.
• Freie Encoder wie FAAC existieren zwar, reichen aber in der Qualität nicht an die kommerziellen bzw. firmeneigenen heran und werden auch nicht mehr weiterentwickelt, da Ahead viele Entwickler angestellt hat, was übrigens auch im Videobereich geschehen ist.

MPEG-4 is an ISO/IEC standard developed by MPEG (Moving Picture Experts Group), the committee that also developed the Emmy Award winning standards known as MPEG-1 and MPEG-2. These standards made interactive video on CD-ROM, DVD and Digital Television possible. MPEG-4 is the result of another international effort involving hundreds of researchers and engineers from all over the world.MPEG-4, with formal as its ISO/IEC designation 'ISO/IEC 14496', was finalized in October 1998 and became an International Standard in the first months of 1999. The fully backward compatible extensions under the title of MPEG-4 Version 2 were frozen at the end of 1999, to acquire the formal International Standard Status early in 2000. Several extensions were added since and work on some specific work-items work is still in progress. MPEG-4 builds on the proven success of three fields:

•  Digitales Fernsehen (HDTV)
•  Interactive graphics applications (synthetic content)
•  Interactives Multimedia (World Wide Web, distribution of and access to content)

2. What's Divx Pro?

DivX Pro TM helps transform a standard desktop computer into a high-quality video studio, distribution centre,and entertainment jukebox. the technology is so advanced that it can reduce a DVD video to almost 10 percent of it's original size, creating great looking files that can be viewed on a PC, television, or DivX certified device with little or no loss in quality.

3. What's Xvid?

Xvid is an ISO MPEG-4 compliant video codec, it is not a product, it's an open source project which is developed and maintained by lots of people from all over the world.

4. What's NERO DIGITAL?

Nero Digital is the world's first complete audio and video codec solution. What does that mean? A "Codec" is short for Compressor-Decompressor. Codecs are needed for encoding (recording) and decoding (playing) audio and video files. With Nero Digital codec you can fit more high quality audio and video content at any given screen size selection whether mobile phones or HDTV,onto CDs, flash memory or hard drives. The Nero Digital codec compresses audio and video content to a fraction of its original size with virtually no perceptual loss of quality. Nero Digital codec also enables you to convert audio and video content into smaller screen formasts at record breaking speeds, allowing you to enjoy playback on Nero Digital Certified mobile phones, PDAs, and portable media players.

Why is Nero Digital better than current codecs? With the technological and communication advances of today's connected age, MPEG-4 was born out of the need for a highly efficient, no compromise audio and video format. In the mobile and digital video camera world, MPEG-4 has quickly established itself as the "codec of choice" for devices such as cameras, mobile phones and other consumer electronic devices.Nero Digital audio and video codecs are completely based on the industry standard MPEG-4 Video (ISO/ICE 14496-2 and MPEG-4 Audio (LC AAC, HE AAC and PS AAC), allowing the flexibility to play other popular MPEG-4 content, yet offering additional features and advanced technology transcending the next 2 decades.

5. H.264 High Definition is the Future

H.264 is the next-generation video compression technology in the MPEG-4 standard, also known as MPEG-4 Part 10. H.264 can match the best possible MPEG-2 quality at up to half the data rate. The intent of H.264/AVC project has been to create a standard contains a number of new features that would be capable of providing good video quality at bit rates that are substantially lower (e.g., half or less) than what previous standards would need (e.g., relative to MPEG-2, H.263, or MPEG-4 Part 2), and to do so without so much of an increase in complexity as to make the design impractical (excessively expensive) to implement. An additional goal was to do this in a flexible way that would allow the standard to be applied to a very wide variety of applications (e.g., for both low and high bitrates, and low and high resolution video) and to work well on a very wide variety of networks and systems (e.g., for broadcast, DVD storage, RTP/IP packet networks, and ITU-T multimedia telephony systems).

(a)The H.264 encoder features:

• 1. Intelligent multi-pass encoding for the best possible results at the desired bit rate with the optimal number of compression passes.
• 2. Time-saving single-pass encoding for creating draft encodes, meeting impending deadlines and live encoding with QuickTime Broadcaster.
• 3. Peak-constrained VBR options for limited data-rate scenarios such as streaming and CD/DVD playback.
• 4. Advanced frame reordering (B-frame) support to more efficiently represent movie data.
• 5. 4x4 integer transform for reducing traditional blocking and ringing artifacts, especially in areas of fine detail.
• 6. Improved intraframe prediction for more efficient compression of details and gradients in high-motion video.
• 7. Increased precision in motion estimation for crisp reconstruction of objects in motion.
• 8. Flexible block sizes in motion estimation for more efficient encoding of complicated motion in areas of fine detail.
• 9. Adaptively tuned in-loop deblocking filter for eliminating blocking artifacts, resulting in a smooth, clean image.

(b) H.264: Making MPEG-4 Better

The original MPEG-4 standard was designed to address the following issues:

• Interoperability. The standard is not specific to any one platform but is designed for all platforms.
• Transport Independence. MPEG-4 leaves the choice of transport mechanism up to the service provider. This allows MPEG-4 to be used in a wide range of networking environments.
• Compression and Transmission of Rich Media. MPEG-4 has been designed for the low and mid bit-rate compression and transmission of rich media streams.
• Interactivity. MPEG-4 allows content authors and viewers to influence how they interact with a stream.
• Scalability. MPEG-4 allows for flexibility in the way multimedia streams are decoded. Decoding bit rate and resolution of content is adapted to the networking environment and display device. This quality is necessary when transmitting rich media over heterogeneous networks, as well as for applications where the receiver is not capable of displaying the full resolution or full quality images.
• Profiles. MPEG-4 offers different technology profiles for different applications. In this way, service providers need not use the entire set of technologies, but only the subset that suits their applications needs.

The JVT has set out several enhancements, which it wishes to achieve in the H.264 standard. These are:

• To simplify the design using well-known building blocks
• To improve the compression performance and reach a 50% or greater bit rate savings from H.263v2 or MPEG-4 Advanced Simple Profile at all bit rates
• Support a flexible application that is appropriate to a variety of services, including low delay (e.g., no B pictures) for real-time conversational services and higher delay appropriate for storage or sever-based streaming applications.
• Ensure network friendliness through ease of packetization, information priority control and application to video streaming services.
• Ensure error resilience through packet loss resilience and mobile channel corruption resilience.
• Full specification of decoding by resolving the mismatch problem (e.g., integer transform, VQ,)
• Performance improvements at higher bitrates
• File storage support that includes simple stream exchange, http streaming service, random access and multiple streams with transitions.

(c) Massive Quality, Minimal Files

H.264 uses the latest innovations in video compression technology to provide incredible video quality from the smallest amount of video data. This means you see crisp, clear video in much smaller files, saving you bandwidth and storage costs over previous generations of video codecs. H.264 delivers the same quality as MPEG-2 at a third to half the data rate and up to four times the frame size of MPEG-4 Part 2 at the same data rate. H.264 is truly a sight to behold.

The Benefits of H.264

• Unprecedented video quality. H.264 uses the latest innovations in video compression technology to provide consistently crisp and clear video for the best possible viewing experience.
• Ultra-efficient. H.264 delivers incredible video quality at data rates one-fourth to one-half the size of previous video formats.
• In contrast to MPEG-4 with its many profiles, H.264 has three profiles, as outlined below:

Wie MPEG-Standards Filme komprimieren

Das Ziel der Standards für die Video-Kompressions ist es, mit möglichst wenig Daten ein Maximum an Bildqualität zu erhalten. Wir zeigen Ihnen, welche Techniken die wichtigsten Standards, MPEG2 und MPEG4, einsetzen. Dabei wird klar, warum das neue MPEG4 Filme besser komprimiert als der alte MPEG2-Standard.

Group of Pictures (GOP) (MPEG4 & MPEG2)
Ein MPEG-Encoder fasst Einzelbilder (Frames) in einer GOP (Group of Pictures) zusammen. Neben den Intra-Frames (Keyframes), die alle Informationen eines Einzelbildes speichern, werden Predicted- und Bidirectional-Frames eingesetzt. Diese P- und B-Frames machen den Großteil einer GOP aus, brauchen aber kaum Platz. Denn sie enthalten keine eigenständigen Bildinformationen, sondern zeigen nur Veränderungen zu vorausgegangenen und nachfolgenden Frames.

Was ist eine GOP struktur
Generell kann man sagen , das es sich hier um die Komprimierung der Mpeg Datei handelt , die GOP Struktur besteht aus 3 Frame Typen
I- Frame Intra Frame : Ein I-Frame beinhaltet das Komplete Bild um es anzuzeigen wird nur das I-Frame gebraucht
P-Frame Predicted Frame : Das P-Frame stellt in zeitlich Positiver Achse die Abhängigkeit der Bilder dar , sie sind also im Prinzip mehr eine Rechenanweisung als ein Bild .Zum Anzeigen eines P-Frames benötigt man die vorhergehenden I und P Frames
B-Frame Bidirectional Frame : B-Frames stellen die Abhängigkeit in zeitlich Positiver oder Negativer Richtung dar . Sie werden mit Hilfe des nächsten Vorhergehenden oder Nachfolgenden I oder P Frames dargestellt . B-Frames haben die höchste Kompression .

Diskrete Cosinus-Transformation (DCT) (MPEG4 & MPEG2)
Zunächst unterteilen die Encoder das Bildmaterial in Blöcke von 8x8 Pixeln. In jedem Block wandelt die Diskrete Cosinus-Transformation die enthaltenen Helligkeits- und Farbinformationen in Frequenzen um, die den Helligkeits- und Farbverlauf widerspiegeln. Dabei schlagen sich Flächen mit feinen Details, die das menschliche Auge kaum wahrnimmt, in hohen Frequenzen nieder. Die anschließende Quantisierung filtert diese hohen Frequenzen heraus und reduziert so drastisch die Datenmenge.

Motion Estimation (MPEG4 & MPEG2)
Die Bewegungsvorhersage (Motion Estimation) ist bei MPEG2/4 Block-basiert. Das bedeutet: Ein MPEG-Encoder unterteilt das Videobild in Makroblöcke zu jeweils 16x16 Pixel. Anschließend prüft der Encoder, wie sich die Position der Makroblöcke in den vorangegangenen und nachfolgenden Frames verändert. Er speichert diese Informationen in Form von Bewegungsvektoren und von Differenzbildern (P- und B-Frames) und spart so eine Menge Platz ein.

Wavelet-Komprimierung (MPEG4)
Zur Bildkompression nutzt MPEG4 neben der Diskreten Cosinus-Transformation auch hoch effiziente Wavelet-Algorithmen, wie sie etwa auch der JPEG2000-Standard verwendet. Das liefert im Vergleich zur DCT eine höhere Bildqualität. Der Grund: Wavelet teilt das Bild nicht in Blöcke auf, sondern wertet das Bild als Ganzes aus. Doch das erfordert einen sehr starken PC.

Advanced Simple Profile (ASP)

http://forum.doom9.org/showthread.php?t=73022

When it comes to DVD Backups the Advanced Simple Profile @ Level 5 (ASP@L5) is the one to follow
It allows frame sizes up to 720x576, frame-rates up to 30fps and offers advanced coding tools like B-Frames (B-VOPS), QuarterPixel Motion Estimation (QPEL), Global Motion Compensation (GMC) and MPEG/Custom Quantization, in contrary to the the Simple Profile, which also only allows a max. frame size of 352x288 and 15fps for example

the most important Advanced Simple Profile tools (not available in Simple Profile) are:

B-Frames/B-VOPS/Bi-directional encoding/prediction:
In contrary to I-Frames/Keyframes (which include the entire image and dont depend on other frames) or P-Frames (which include only the changed parts of the image from the previous I- or P-Frame), B-Frames are constructed using data from the previous and next I- or P-Frame. B-Frames can be compressed much more than other frame types, which overall should help quality and compressibility.

Quarter Pixel Motion Search Precision (QPEL):
basically most MPEG-4 codecs by default detect motion between two frames down to half a pixel (HalfPel)
Now with QuarterPel you can detect motion that is only a quarter of a pixel per frame, effectively doubling precision!
practically this means that you will get a much sharper image with QPEL, try it and you will love it (that's my opinion of course )

Global Motion Compensation (GMC):
GMC detects if there is an amount of motion big parts of the frame have in common. If thats the case GMC kicks in, using a single motion vector for all similar parts of the frame instead of multiple ones.
practically this helps saving bits when panning, zoom or rotation occurs (depending on how good the GMC implementation is/offered warppoints), bits which than can be used somewhere else, for example where they bring more sharpness.

MPEG/Custom Quantization:
While with MPEG-4 Simple Profile you can only use the h.263 quantization type, the ASP also allows you to use custom ones
While the h.263 type will bring you a softer image (good for 1CD encodes), the default MPEG matrix is better for higher bitrates, preserving more details
a popular custom matrix is for example hvs_good, also nice for lower bitrates, but there are also many more

Adaptive Quantization:
When encoding with a Variable Bitrate (eg in 2pass) each frame can get compressed with a different quant (the higher the quant the smaller the size/bitrate of the frame). What frame gets what quant (eg compress high motion more) is decided by the "Rate Control".
With Adaptive Quantisation (also available in Simple Profile) the quant can additionally also differ inside each frame (eg high motion/dark parts of the frame get a higher quant/compressed more, faces get a lower quant than background, aso...)

WMV9 Advanced Profile (WVC1) video codec BETA has been released!

Official thread: Windows Media Video 9 Advanced Profile / VC-1 AP

Q: Where can I get the latest and greatest WMV9 Advanced Profile (WVC1) codec?
A: There are several existing ways to get the WVC1 codec, and a few more will be made possible soon.

• Windows Media Player 11 for XP - WMP11 BETA for XP includes the most recent build of WVC1 encoder and decoder DMOs. Make sure you read the release notes for troubleshooting, known issues and uninstall instructions before installing the beta Player. If you install Windows Media Encoder 9 Series and build a custom session, the codec will show up as "Windows Media Video 9 Advanced Profile" in the dropdown list.
• Windows Media Encoder Studio Edition - The upcoming beta release of WME SE supports Advanced Profile encoding. The software should be available for download soon (I don't know how soon though).
• Windows Media Player 11 for Vista - All beta versions of Windows Vista (except "N" European versions) include the WVC1 encoder (wmvencod.dll) and decoder (wmvdecod.dll) DMOs. Beta2 is now available for download!
• Windows Media Encoder 9 Series x64 Edition - The x64 edition of WME9 contains the WVC1 encoder, but it's an older version than the ones included with WMP. Also, note that WME x64 requires 64-bit source codecs, too.
• Microsoft is also actively working on making a standalone WMV9 AP codec package available for download to users who want to test the beta codec but don't want to install the Player beta. More info soon.

Q: What is VC-1? What is WMV9? What's the difference?
A: VC-1 is a codec specification as standardized by SMPTE in 421M. WMV9 is an implementation of that specification. Think of it this way: WMV9 is to VC-1 what x264 is to MPEG-4 AVC. In the context of Microsoft video codecs, WMV9 and VC-1 can be considered one and the same. Note, however, that in the future other companies may choose to implement VC-1 codecs, too.

Q: So what's the big deal with Advanced Profile? Is it a new codec?
A: In some ways it is a new codec... in others, it's just an extension of the standard WMV9 codec. The SMPTE standard for VC-1, SMPTE 421M, was originally based on Microsoft's Windows Media Video 9 codec. However, a number of changes and improvements were made to the specification as a part of the SMPTE standardization. Three profiles were defined for VC-1: Simple, Main and Advanced Profile. The existing implementation of WMV9 (FourCC: WMV3) covered Simple and Main profile, so Advanced was yet to be implemented. Advanced Profile included new features such as true interlaced encoding support, resolutions up to 2048x1536 and bitrates up to 135Mbps.

Q: But wait! Didn't WMP10 ship with a WMV Advanced Profile codec?
A: Yes, it did. Microsoft began working on its implementation of WMV AP before VC-1 was finalized. The codec (FourCC: WMVA) shipped with WMP10 (Format SDK 9.5), but as final changes to the VC-1 spec were made, WMVA got out of sync with the spec. Today WMVA is no longer VC-1 compliant and is generally considered deprecated.

Q: Does the new Advanced Profile codec have a different FourCC?
A: Yes, it does. In order to differentiate it from SP/MP codec (FourCC: WMV3) and the non-VC1-compliant AP codec (FourCC: WMVA), and avoid issues with legacy decoders, the VC-1 compliant WMV9 Advanced Profile codec uses a new FourCC code: WVC1.

Q: How do I configure the advanced settings of WMV9 AP? I don't see any UI in WME9 to do this!
A: The advanced settings of the WMV9 Advanced Profile codec are enabled through registry settings. This is because the codec must work with Windows Media Encoder, which has not been updated since Windows Media 9 Series and therefore does not have any user interface elements for the new codec. Yeah, it's not the greatest and user friendliest interface, but it's actually how most codecs store their long term settings. The difference is only that there is no UI for these settings yet. So if anybody's bored and wants to put their coding skills to use...

Q: Where can I find out more about VC-1 and WMV9 Advanced Profile?
