multicamera MP4 set: recover after deletion
How can I recover synchronized MP4 clips from several cameras after deletion?
Short answer
Yes, card by card: deleted clips from each camera stay recoverable until that card is recorded over. Label every card with its camera, scan each one read-only on its own and export into separate folders, so file names repeated across cameras do not collide and the angles can be resynced by timecode.
The situation
synchronized MP4 clips from several cameras no longer appears in its recording folder even though the storage device is still detected.
Each camera holds its own card and its own deleted clips, so this is several separate recoveries rather than one. The angles were deleted at different moments and the cards saw different amounts of recording afterwards, which is why one camera can come back complete while another is already partly overwritten.
01 / Diagnose
Work out what actually disappeared
Deleting a clip releases its directory entry, and the footage survives until new recording claims the clusters. In a multicamera set the file names repeat, because cameras of the same model start numbering at the same clip number. Nothing tells the angles apart except the card they came from and the timecode written inside the files.
Deletion can release a directory reference before later writes reuse every block that belonged to the file. For multicamera MP4 set, this matters because matching time ranges, camera IDs and audio references are needed to rebuild the production set
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Collect every card, switch the cameras off and label each card with the camera it belongs to before anything goes into a reader.
- 2
Note the roll, the shooting day and the timecode source per camera, so that recovered clips can be matched to an angle later.
- 3
Scan the cards one at a time read-only and export each camera into its own folder, so identical clip numbers cannot overwrite each other.
- 4
Line the recovered angles up by timecode or by the audio waveform, then check that every take is covered by all cameras.
Do not connect several cards at once and export everything into a single folder: identical file names from different cameras then replace one another silently. Do not carry on shooting with any of these cards while the recovery is still open.
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 exFAT, NTFS and FAT16/FAT32 cards read-only on macOS and Windows and recovers them card by card; it does not merge angles, read timecode or rebuild a production set. Clips already recorded over come back incomplete or not at all.
04 / Verify
Check the recovered content, not just its name
The set is usable when every camera contributes an unbroken clip for each take and the angles line up on a common timecode or audio sync without drifting apart. Play each recovered clip to its end and confirm that the file count per camera matches the shooting notes.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can multicamera exFAT cards be recovered in this situation?+
Each camera holds its own card and its own deleted clips, so this is several separate recoveries rather than one. The angles were deleted at different moments and the cards saw different amounts of recording afterwards, which is why one camera can come back complete while another is already partly overwritten. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not connect several cards at once and export everything into a single folder: identical file names from different cameras then replace one another silently.
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?+
The set is usable when every camera contributes an unbroken clip for each take and the angles line up on a common timecode or audio sync without drifting apart.
