variable-frame-rate MP4: recover after deletion
How can I recover VFR MP4 camera clips after deletion?
Short answer
Yes, often: deleted VFR clips from action cameras, drones or phones with memory cards stay recoverable until new footage overwrites them. Stop filming, remove the card and scan it read-only. Note the device and app that recorded them, because the variable frame timing lives in the MP4 index and some editors need a constant-rate copy.
The situation
VFR MP4 camera clips no longer appears in its recording folder even though the storage device is still detected.
Deleted VFR clips from phones, drones and action cameras stay on the memory card until something writes over them. What makes this case different is not the recovery itself but the timing: a VFR clip stores a timestamp per frame instead of a fixed rate.
01 / Diagnose
Work out what actually disappeared
Deletion on exFAT releases the directory entry and leaves the payload untouched. The frames and the per-frame timestamps are both inside the file, so a clean recovery brings the original timing back with it. The complication appears afterwards, in editing software that expects a constant frame rate and drifts against the audio when it does not get one.
Deletion can release a directory reference before later writes reuse every block that belonged to the file. For variable-frame-rate MP4, this matters because timestamps rather than a fixed frame count define the presentation timeline
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Stop filming and take the card out of the device; on a phone, switch off camera and cloud sync before anything else.
- 2
Write down the recording device and the app that produced the clips, because the timing behavior differs between them.
- 3
Scan the card read-only with File Recovery Hero and export the clips to a computer disk, not back to the card.
- 4
Keep the exported VFR file as the master and convert a copy to a constant frame rate only for editing.
Do not shoot again on the same card to check whether the camera still works, and do not let a media app transcode the recovered clips automatically. A conversion discards the per-frame timestamps, and the original timing cannot be worked out from the result.
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 and exports the clips as they were recorded; it does not convert frame rates or rebuild timing a transcode removed. Clips whose blocks were overwritten come back partial. Scanning is free, export needs the 50 € license.
04 / Verify
Check the recovered content, not just its name
Open each recovered clip and check the reported frame rate; a VFR file often shows an average rather than a round number. Play it to the end and watch whether speech stays in sync. Drift that grows over the clip points at timing lost in a conversion, not at a bad recovery.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can VFR camera media be recovered in this situation?+
Deleted VFR clips from phones, drones and action cameras stay on the memory card until something writes over them. What makes this case different is not the recovery itself but the timing: a VFR clip stores a timestamp per frame instead of a fixed rate. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not shoot again on the same card to check whether the camera still works, and do not let a media app transcode the recovered clips automatically.
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?+
Open each recovered clip and check the reported frame rate; a VFR file often shows an average rather than a round number.
