That would be the "credits".

The index file does contain the byte offset of each frame, so basicly it should
be possible to calculate the total size (in bytes) of the edited version before
actually running the cutting operation. You'll need to be careful with segments
that start in one file and end in the next file, because the offsets always start
at zero with every new file.
