Fix a corrupted Xbox Game Bar capture that won't play.
When Xbox Game Bar is interrupted mid-capture, the MP4 in your Captures folder keeps its footage but loses the index that makes it playable. Upload it and we'll try to rebuild it.

We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.

Try a deep repair
The repair engine can try a longer pass on the file you already uploaded.
Machine-only processing; no human views files; nothing is sent to an outside AI.
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.
Right now we repair video, audio, document, and image files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, FLV, M4A, WAV, MP3, AAC, FLAC, OGG, OPUS, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, RAR, PDF, AI, HEIC, and HEIF). We're adding support for more formats over time.

Why Game Bar captures end up broken
Windows' Xbox Game Bar (Win+G) records gameplay to an MP4 in your Videos\Captures folder. Like every MP4 recorder, it writes the footage as it goes but only writes the index — the block a player needs to open the file — when the capture is stopped cleanly.
If the game crashes, Windows closes the app, the PC sleeps, or the capture is cut off mid-write, that index is never finished. The clip sits in your Captures folder at a normal size but won't open in any player.
The footage is generally intact, so this is often recoverable. FileFix reads what Game Bar wrote, rebuilds the index, and returns a playable file — with a free preview of exactly how much was recovered before you pay.
The one case we can't fix: a 0-byte or empty capture, where recording stopped before any footage was written. We'll say so plainly and you won't be charged.
What we can and can't fix
We can usually fix
- A Game Bar capture was cut off mid-record, leaving footage in the Captures folder with no working index.
We can't fix
- The capture is 0 bytes or empty because it stopped before writing footage. There's nothing to rebuild. More on that →

Questions
It has footage but no finished index, so it looks like a normal file while no player can open it. Rebuilding that index is what we do, and the free preview shows the result before you pay.
Yes. Game Bar can capture apps and the desktop too, and those MP4s fail and recover the same way. See our Windows screen recording page, or just upload the file.
