Formats supported Audio formats supported Video formats supported Caption (Subtitle) formats supported See also Notes and references- ^ The ability to hold additional files such as fonts for subtitles etc.
- ^ ACM cannot handle VBR audio streams in AVI files. Thus, software using ACM to read audio from AVI files will not be able to handle VBR audio streams correctly, even though such files are compliant to the AVI file specification. This is a limitation of the ACM, not of the AVI file format.
- ^ Although AVI is not designed for variable framerates, it is possible to use them without creating a non-standard file by using 0-byte chunks for skipped frames. However it requires framerate to be set to Least common multiple of all framerates used, and produces slight overhead compared to true VFR.
- ^ Although FFmpeg has introduced a solution to put Vorbis audio into AVI files, this "extension" is not compatible with existing Vorbis decoders for DirectShow and ACM. Putting Vorbis in an AVI container is very problematic. The way Nandub stored Vorbis audio streams in AVI files occasionally caused desychronisation when seeking.

- ^ Specification for embedding WebVTT in a WebM container is in the works.
- ^ WebM limits support to VP8 and vorbis.
- ^ WebM is focused on addressing the unique needs of serving video on the web.
- ^ Rockchip demonstrated full WebM hardware playback.
- ^ Older types of RealAudio (including ATRAC3)use constant bitrate compression, and therefore are fully compatible with the ancient ACM interface. Newest type of RealAudio is actually AAC, which never has been a problem to the DirectShow-based decoders.
- ^ There is a value in the stream headers, called dwSampleSize, which is 0 in order to trigger VBR stream seeking. This is officially documented in the MSDN and not a hack, bug or whatever. The way MP3-VBR and AAC are stored in AVI are specified and completely compliant with the AVI file specification.
- ^ The Matroska developers were awaiting the release of Musepack 8.x, as this version would completely change the bitstream, however Musepack 8 still is unsuitable for any sanely designed container.
- ^ According to "ETSI TS 102 366 v1.2.1 - Digital Audio Compression (AC-3, Enhanced AC-3) Standard, Annex F"
- ^ Through an updated x264/ffdshow filter it is possible to view H.264 in an AVI file.
