Recover video from an exFAT SDXC card
How can I recover MP4, MOV, or MXF from SDXC?
Short answer
Only by scanning for the exact container your camera recorded, MP4, MOV or MXF, before the card records again. Large video spans many clusters, so even with a surviving exFAT entry parts can be fragmented or reused. Scan read-only, export to another drive and validate every stream across the full duration.
The situation
Camera clips are deleted or absent after ingest.
Video behaves differently from stills on the same card. A single clip can occupy several gigabytes across thousands of clusters, so it is both the first thing a new recording overwrites and the hardest file to reassemble once the directory entry is gone.
01 / Diagnose
Work out what actually disappeared
Cameras write MP4, MOV or MXF, and each container has its own structure that a scan must recognise. Long takes are often split into chapter files around the 4 GB mark, so one recording can exist as several files. If clusters of a clip were partly reused, the result is a file that starts correctly and then breaks.
Large video extents are vulnerable to reuse and fragmentation, even when the exFAT entry still survives.
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 recording on the card at once; a single new take can cover many gigabytes of the deleted material.
- 2
Note which container the camera produces and the approximate length of each missing clip from the shooting log.
- 3
Scan the exFAT card read-only for that container alone, so the results are not buried under thousands of thumbnails.
- 4
Export to a drive with room for the whole card, then play each clip through instead of trusting the preview frame.
Do not let an editing application transcode or write proxies onto the source card while clips are missing, and do not format it because the export looked incomplete. A second scan with other settings is still possible as long as the card stays untouched.
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.
Fragmented clips whose pieces are partly overwritten cannot be put back together, and a container missing its index needs repair software. File Recovery Hero reads the exFAT card read-only, exports to another drive and labels results it could not confirm as UNVERIFIED.
04 / Verify
Check the recovered content, not just its name
Check each clip across its whole length rather than at the start: scrub to the middle and the end, listen for audio all the way through, and compare the duration with what was shot. A file that plays for ten seconds and then freezes is a fragment, not a take.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can exFAT SDXC video card be recovered in this situation?+
Video behaves differently from stills on the same card. A single clip can occupy several gigabytes across thousands of clusters, so it is both the first thing a new recording overwrites and the hardest file to reassemble once the directory entry is gone. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not let an editing application transcode or write proxies onto the source card while clips are missing, and do not format it because the export looked incomplete.
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?+
Check each clip across its whole length rather than at the start: scrub to the middle and the end, listen for audio all the way through, and compare the duration with what was shot.
