Free Online AAF to OGG Converter

AAF is a format created for storing results of nonlinear post-production video processing. AAF is a non-linear editing analog of EDL format. It is cross-platform interoperable and designed to replace OMFI, so a wide variety of manufacturers support AAF in their authoring software. AAF encapsulates metadata, program content and its history, source elements, remote online content, rich set of built-in standard media effects, HTML/XML content and localizations.

This format is free, which apparently is one of the reasons for its popularity. The used codecs supports variable bit rates (as a default), and .ogg files usually play back easily on all platforms. All things being equal, the sound quality exceeds that of mp3 somewhat.
