Why Video repair FAQ corruption is more common than drive failure
Flash storage and modern codecs are reliable; what fails is the write lifecycle. Devices buffer frames in RAM, then commit container indexes on stop. Any interruption between start and finalize leaves a file that looks complete in the filesystem listing but lacks the timeline metadata players require. That is why two files from the same shoot can behave differently—one stopped cleanly, one did not.
Cloud sync tools sometimes upload partial files while the camera is still writing, producing a “successful” backup that is truncated at the cloud side. Always recover from the original card when possible, then upload the untouched corrupt capture to FixCorruptVideo.
Security, retention, and guest checkout
We delete uploads, previews, and outputs automatically after 24 hours. Checkout is guest-first via Polar.sh. You receive a download link valid within the retention window; save the repaired file locally immediately for editing or archival.
We do not sell uploaded footage. Each repair runs in an isolated job workspace on our servers and is removed when retention expires.
What happens when you press Repair
We diagnose structure and decode behavior, then apply ordered repair strategies until a file passes verification. That includes remux, moov relocation, reference-based rebuild when you provide a matching clip, and controlled re-encode only when necessary.
We generate the 15-second watermarked preview only after null-decode and seek tests succeed — so you do not pay for a file that still freezes at zero seconds.
When to escalate with a reference clip
If our scanner reports missing moov metadata or asks for a reference, upload a short healthy clip from the same device with identical resolution and frame rate. Reference-based rebuild often makes the difference between total loss and a fully editable timeline.
Avoid references that were sent through chat apps or social networks; recompression changes headers and lowers match quality.
Frequently asked questions

- MP4, MOV, MKV, AVI, WebM, MTS, and more — see format hubs under /repair.
- Do I need a reference file?
- Often for missing moov metadata from interrupted recordings. A short healthy clip from the same camera improves recovery.
