MOV with timecode and multichannel audio: recover after an interrupted recording
What can I do with MOV clips with timecode and multiple audio tracks after a recording interruption?
Short answer
Not just the picture needs rebuilding: power loss can leave the MOV without its index, and a repair may restore video while dropping audio tracks or timecode. Keep the original untouched, repair only a copy using a reference clip with the same channel layout and timecode base, then check sync.
The situation
MOV clips with timecode and multiple audio tracks is missing, too short or unreadable after power loss, a card error or an unsafe stop.
An interrupted MOV on this card is rarely empty. The recorder wrote picture, timecode track and each audio channel into the file, then lost power before the closing atom that tells a player where those streams begin and end. That is why the clip shows as zero length or refuses to open at all.
01 / Diagnose
Work out what actually disappeared
Power loss during recording leaves the exFAT directory entry with a stale size, and the MOV itself without final sample tables. Video, timecode and the separate audio timelines were interleaved as they arrived, so the data is present but unindexed. Cameras that write the index last are especially affected; the take before the interrupted one is usually complete.
The payload may have been written before duration fields, indexes, directory entries or closing structures were committed. For MOV with timecode and multichannel audio, this matters because video, timecode and several audio timelines must all survive together
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Switch the recorder off before anything else, eject the card and set a write-protect switch if the card carries one.
- 2
Note the timecode base, the number of audio channels and the camera model, then list which clip numbers the card still shows.
- 3
Read the card only, either by copying the whole card structure to a disk or by scanning the exFAT volume read-only with File Recovery Hero.
- 4
Export to a different drive, then hand the copy, never the original, to a repair tool together with an intact reference clip from the same camera mode.
Do not let the camera format or check the card, and do not run a disk repair utility on it. Both write to the volume that still holds the interrupted take. Avoid repairing the original file in place; a failed rebuild can overwrite the audio tracks you still need.
03 / Choose the method
Match the tool to the source
For stable, readable exFAT, NTFS and FAT16/FAT32 or uncompressed IMG, DD, RAW and BIN images.
Unconfirmed exports are marked .UNVERIFIED.
File Recovery Hero reads the exFAT card and exports what is there; it does not rebuild a broken MOV container. Timecode and extra audio tracks come back only if they were written before the interruption. Scanning is free, exporting needs the 50 € license.
04 / Verify
Check the recovered content, not just its name
A usable result opens from first frame to last, reports a duration close to what the shoot log says, and lists every audio track the recorder was set to capture. Play the end of the clip, not only the start, and confirm that timecode runs continuously rather than resetting to zero.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can exFAT video media be recovered in this situation?+
An interrupted MOV on this card is rarely empty. The recorder wrote picture, timecode track and each audio channel into the file, then lost power before the closing atom that tells a player where those streams begin and end. That is why the clip shows as zero length or refuses to open at all. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not let the camera format or check the card, and do not run a disk repair utility on it.
Does scanning write to my memory card?+
Your memory card is only read. Nothing is saved to it.
How do I know whether the result is complete?+
A usable result opens from first frame to last, reports a duration close to what the shoot log says, and lists every audio track the recorder was set to capture.
