* H. 264 also known as MPEG-4 Part 10, or as AVC, used for Blu-ray Discs and some broadcast television formats

The next enhanced codec developed by ITU-T VCEG ( in partnership with MPEG ) after H. 263 is the H. 264 standard, also known as AVC and MPEG-4 part 10.

* Coding of video coding H. 262 / MPEG2-Video and H. 264 / MPEG-4 AVC

Some well known designs that have this capability include JPEG 2000 for still images and H. 264 / MPEG-4 AVC based Scalable Video Coding for video.

* MPEG-4 Part 2 and Part 10 ( AVC )

It was formed in 2001 and its main result has been H. 264 / MPEG-4 AVC ( MPEG-4 Part 10 ).

** MPEG-4 AVC ( or MPEG-4 Part 10 or H. 264 ).

The key parts to be aware of are MPEG-4 part 2 ( including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by QuickTime 6 ) and MPEG-4 part 10 ( MPEG-4 AVC / H. 264 or Advanced Video Coding, used by the x264 encoder, by Nero Digital AVC, by QuickTime 7, and by high-definition video media like Blu-ray Disc ).

Sony decided to choose Memory Stick Video format ( which actually is H. 264 / MPEG-4 AVC format ) as standard for Walkman MP3 Video Player.

* Nero Digital: Commercial MPEG-4 ASP and AVC codecs developed by Nero AG.

There are two DivX codecs ; the regular MPEG-4 Part 2 DivX codec and the H. 264 / MPEG-4 AVC DivX Plus HD codec.

* Scalable Video Coding, an extension of the video compression standard H. 264 / MPEG-4 AVC

Fifth and sixth generation iPod classics, as well as third generation iPod nanos, can additionally play MPEG-4 ( H. 264 / MPEG-4 AVC ) and QuickTime video formats, with restrictions on video dimensions, encoding techniques and data-rates .< ref > The restrictions vary from generation to generation ; for the earliest video iPods, video is required to be Baseline Profile ( BP ), up to Level 1. 3, meaning most significantly no B-frames ( BP ), a maximum bitrate of 768 kb / s ( BP Level 1. 3 ), and a maximum framerate of 30 frame / s at 320 × 240 resolution.

It was announced on 10 February 2009 that the signal would be encoded with MPEG-4 AVC High Profile Level 4, which supports up to 1080i30 / 1080p30, so 1080p50 cannot be used.

* Video formats: Cinepak, DV, H. 263, H. 264 / MPEG-4 AVC, HuffYUV, Indeo, MJPEG, MPEG-1, MPEG-2, MPEG-4 Part 2, RealVideo, Sorenson, Theora, WMV, Bink

An AVI file may carry audio / visual data inside the chunks in virtually any compression scheme, including Full Frame ( Uncompressed ), Intel Real Time ( Indeo ), Cinepak, Motion JPEG, Editable MPEG, VDOWave, ClearVideo / RealVideo, QPEG, and MPEG-4 Video.

Approaches exist to support modern video compression techniques ( such as MPEG-4 ) which rely on this function, although this is beyond the intent of the original specification and may cause problems with playback software which does not anticipate this use.

With the help of standard procedures, MPEG-4 data can be interpreted and transformed into other signal types compatible with any available network.

The MPEG-4 format can perform various functions, among which might be the following:

For example, video created with a standard MPEG-4 Part 2 codec such as Xvid can be decoded ( played back ) using any other standard MPEG-4 Part 2 codec such as FFmpeg MPEG-4 or DivX Pro Codec, because they all use the same video format.

3ivx provides plugins and filters that allow the MPEG-4 data stream to be wrapped by the Microsoft ASF and AVI transports, as well as Apple's QuickTime transport.

Technology improvements can be found in the designs of H. 263v2 Annex I and MPEG-4 Part 2, which use frequency-domain prediction of transform coefficient values, and in H. 264 / MPEG-4 AVC, which uses spatial prediction and adaptive transform block size techniques and more sophisticated entropy coding than what was practical when the first JPEG design was developed.

* The Irish system, as to be used by both RTÉNL and any subsequent commercial DTT provider is a MPEG-4 DVB-T service with an MHEG-5 interactive layer.

The representation that is defined within MPEG-4, i. e. the representation of audio-visual data in terms of objects, is however very well suited to what will be built on the MPEG-7 standard.

Since Xvid uses MPEG-4 Advanced Simple Profile ( ASP ) compression, any video that is encoded with it is termed " MPEG-4 ASP video " – not " Xvid video " – and can therefore be decoded with all MPEG-4 ASP compliant decoders.

The intent of the H. 264 / AVC project was to create a standard capable of providing good video quality at substantially lower bit rates than previous standards ( i. e., half or less the bit rate of MPEG-2, H. 263, or MPEG-4 Part 2 ), without increasing the complexity of design so much that it would be impractical or excessively expensive to implement.

Typically the distribution system for Standard Definition digital TV is based on the MPEG-2 specification, while High Definition distribution is likely to be based on the MPEG-4 meaning that the delivery of HD often requires a new device or set-top box, which typically are then also able to decode Internet Video via broadband return paths.

New developments in video compression have resulted in the H. 264 / MPEG-4 AVC standard which enable three high-definition television services to be coded into a 24 Mbit / s European terrestrial transmission channel.

Cinepak files tend to be about 70 % larger than similar quality MPEG-4 or Ogg files.

* m4a – An audio-only MPEG-4 file, used by Apple for unprotected music downloaded from their iTunes Music Store.

It is also used on Blu-ray Discs, but these normally use MPEG-4 Part 10 or SMPTE VC-1 for high-definition content.

* Parametric Stereo, Audio Object Type defined and used in MPEG-4 Part 3 ( MPEG-4 Audio ) to further enhance efficiency in low bandwidth stereo media

LPC predictors are used in Shorten, MPEG-4 ALS, FLAC, and other lossless audio codecs.

Even the original DVB standards can carry more HDTV channels in a multiplex if the most advanced MPEG-4 compressions hardware is used.

* FFmpeg MPEG-4: Included in the open-source libavcodec codec library, which is used by default for decoding or encoding in many open-source video players, frameworks, editors and encoding tools such as MPlayer, VLC, ffdshow or GStreamer.

Variable bit rate encoding is also commonly used on MPEG-2 video, MPEG-4 Part 2 video ( Xvid, DivX, etc.

* Error Resilience, an audio coding method used in MPEG-4 Part 3

* SinuSoidal Coding used for audio in MPEG-4 Part 3

When motion prediction is used, as in MPEG-1, MPEG-2 or MPEG-4, compression artifacts tend to remain on several generations of decompressed frames, and move with the optic flow of the image, leading to a peculiar effect, part way between a painting effect and " grime " that moves with objects in the scene.

The default MPEG-4 codec used by FFmpeg for encoding has the FourCC of FMP4.

AAC, on the other hand, normally uses a pure MDCT ; only the ( rarely used ) MPEG-4 AAC-SSR variant ( by Sony ) uses a four-band PQF bank followed by an MDCT.

H. 264 / MPEG-4 Part 10 or AVC ( Advanced Video Coding ) is a standard for video compression, and is currently one of the most commonly used formats for the recording, compression, and distribution of high definition video.

* Scalable Sample Rate, used in MPEG-4 Part 3 and MPEG-2 Part 7
