  4. 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.
  5. 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.
  6. 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.
