Failure modes:
The causes of failure reported by Canon EOS users needing to repair files are:
- Camera froze during recording or upon stopping the shot and doesn't respond
- Last clip recording went fine but playback is not available
- "Cannot playback movie" error message
- Crash during file transfer from CF card
- Unplayable .DAT video file
- Clips deleted, card formatted by mistake
- Clip not recognized after transfer, cannot play
- Battery dead during recording
- Bitstream corruption (rare)
Repairability:
The damaged files cannot be opened because recording did terminate abruptly: While the media (video and audio) is present and not corrupt, the index and header of the movie indicating what the data means, is not present.
Repair consists in reindexing the movie.
