variable-frame-rate MP4: find after an import failure
Where are VFR MP4 camera clips after a failed import?
Short answer
First look in the destination folder, the trash and the editor's catalog: some apps convert VFR footage to constant frame rate on import, and a converted copy can hide that the original never arrived intact. If the source was deleted after import, scan the unused card read-only and keep the original VFR file for the edit.
The situation
VFR MP4 camera clips is incomplete at the destination and no longer appears reliably on the source.
There may be two versions of the same take. Some editing apps convert VFR footage to a constant frame rate while importing, so a converted file in the project can sit next to an original that never arrived complete, or no longer exists.
01 / Diagnose
Work out what actually disappeared
An import can create a transcoded copy, catalog it and then clear the card, which hides whether the original transferred at all. If the conversion itself was interrupted, the project holds a short constant-rate file while the full VFR recording is only on the card. Either way, the file in the timeline is not the camera original.
Move, rename, catalog and delete-after-import steps can fail at different moments and leave source and destination in different states. 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
Quit the editing application before it re-imports anything, and disconnect the card so no delete step can run.
- 2
Look in the destination folder, the trash and the media cache for both a converted copy and a VFR original.
- 3
Compare what you find with the clip list on the card, checking durations rather than only filenames.
- 4
Copy any missing original from the card by hand, or scan the card read-only if it is empty, and export elsewhere.
Do not build the edit on the converted copy and erase the card, and do not repeat the import while the incomplete conversion is still in the project folder. A converted file cannot be turned back into the original variable timing.
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 volumes and uncompressed images read-only on macOS and Windows. It does not look inside an editing project, undo a transcode or read APFS, HFS+ or ext4 media. Scanning is free, exporting needs the 50 € license.
04 / Verify
Check the recovered content, not just its name
The original is identifiable by its length and its reported average frame rate, which rarely lands on a round value. Confirm that it plays from beginning to end with sound in step. A converted copy of the same take will be the same length but show a fixed rate.
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?+
There may be two versions of the same take. Some editing apps convert VFR footage to a constant frame rate while importing, so a converted file in the project can sit next to an original that never arrived complete, or no longer exists. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not build the edit on the converted copy and erase the card, and do not repeat the import while the incomplete conversion is still in the project folder.
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 original is identifiable by its length and its reported average frame rate, which rarely lands on a round value.
