Index Section

The index section is written to maintain possible future compatibility with Microsoft Media Player and is not presently used by programs that read AMF files. Documentation for the AVI format is available in the Microsoft AVI RIFF File Reference.

The AMF footer is stored as a JUNK chunk at the very end of the file, as seen in this HEX dump:
