proxy and camera-original MP4: recover after a quick format
Can missing camera originals with surviving proxies be recovered after a quick format?
Short answer
Often, if no new clip was recorded: a quick format removes the records of proxy and original folders together, but both kinds of data can remain. Eject the card. After a read-only scan, sort the hits by size, because small proxies and large originals of the same take will both turn up.
The situation
The medium now has a new empty directory, while the previous missing camera originals with surviving proxies is missing.
A quick format rewrote the card exFAT bookkeeping, not its contents. Both folders vanished at once, which is why the proxies disappeared together with the originals, yet the recorded blocks of either kind are still lying in the data area untouched.
01 / Diagnose
Work out what actually disappeared
Formatting quickly means writing a fresh directory and allocation table over the old ones; the camera reports an empty card within seconds because it never touches the payload. Proxy files and full-resolution MP4s were stored in separate folders, so after the format they surface as two size classes of the same takes rather than as a folder tree.
A quick format can replace file-system records without immediately overwriting every older content block. For proxy and camera-original MP4, this matters because small proxy files can survive in a separate folder while high-resolution originals are absent
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Eject the freshly formatted card at once and resist the reflex to shoot a test clip to see whether the camera is fine.
- 2
Write down what was on the card before the format: how many takes, roughly how long, and whether proxies came from the camera or from the editor.
- 3
Scan the card read-only from a reader; with the directory gone, expect results sorted by signature and size instead of by original folder names.
- 4
Export everything to another drive, then split the results into large originals and small proxies by file size before renaming them.
Do not format again in the hope of a cleaner result, and do not choose a full format when the card is prepared later; that pass writes across the whole surface. A single new recording can land exactly on the originals you are trying to get back.
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.
A quick format leaves data behind, a full format usually does not, and no scan can read blocks that were rewritten. File Recovery Hero exports files as it finds them and does not restore folder names, project links or camera databases. Scanning is free, export needs a 50 € license.
04 / Verify
Check the recovered content, not just its name
Judge by pairs. Each take should appear twice, once as a small proxy and once as a large original of the same length. Play the last thirty seconds of a recovered original; a file that ends abruptly or shows blocky frames was partly overwritten before the format.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can camera and proxy media be recovered in this situation?+
A quick format rewrote the card exFAT bookkeeping, not its contents. Both folders vanished at once, which is why the proxies disappeared together with the originals, yet the recorded blocks of either kind are still lying in the data area untouched. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not format again in the hope of a cleaner result, and do not choose a full format when the card is prepared later; that pass writes across the whole surface.
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?+
Judge by pairs.
