Fix a corrupted OBS recording that won't play.
If OBS crashed or was force-closed before you hit Stop, your recording is usually still there — it just never got the index that makes it playable. Upload it and we'll try to rebuild it.

There's nothing to repair. If it still looks broken, the issue may be the player, codec, or viewer on your device rather than the file itself.
We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.
Have another clip from the same device?
A healthy video recorded on the same device — ideally the same settings — gives the repair engine a template to rebuild from. It can unlock repairs that fail on their own.
Unrepaired files are kept encrypted for up to 30 days, then deleted.
FileFix can't fix that kind of file yet.

Why OBS recordings won't play after a crash
OBS Studio writes your footage to an MP4 or MOV as it records, but the index that lets a player seek and play the file — the moov atom — is only written the moment you press Stop and OBS finalizes the file.
If OBS crashes, your PC locks up, the encoder hits an error, or the app is killed before you stop the recording, that finalizing step never happens. The footage is on disk, but every player opens the file, can't find the index, and refuses to play it. This is why an OBS file can be gigabytes in size and still "not work."
Because the footage is intact, this is very often recoverable. FileFix reads what OBS wrote, rebuilds a valid index around it, and produces a file that plays normally. You'll see how much was recovered in a free preview before paying. Tip for next time: OBS's MKV or hybrid-MP4 output survives crashes far better than plain MP4 — but that doesn't help the file you already have, and that's the one we fix.
The one case we can't fix: if OBS crashed before writing any footage, leaving a 0-byte or empty file, there's nothing to rebuild. We'll tell you plainly and there's no charge.
What we can and can't fix
We can usually fix
- OBS was killed or crashed before you pressed Stop, so the file has footage but no index — the most common OBS recording failure.
We can't fix
- The recording is 0 bytes or empty because OBS died before writing any footage. There's nothing to rebuild. More on that →
How it works
-
Upload Drop a supported video file in. It uploads over an encrypted connection. The repair runs automatically — no person watches your file.
-
Free Watermarked Preview You see a free watermarked preview and exactly how much we recovered.
-
Pay & Download If it's right, you pay $19 once and download a clean, full-quality MP4.
About half of real-world corrupted files repair fully, and you always preview before paying.

Questions
Yes — both use the same kind of index that goes missing on a crash. If you recorded to MKV and it won't play, upload it too; the preview will show what we can recover.
The file has data but no index, so file-size looks normal while every player fails to open it. Rebuilding the index is exactly what we do; the free preview confirms it before you pay.
Yes. Streamlabs is built on OBS and fails the same way — see our Streamlabs page, or just upload the file here.
