RECORDING STOPPED. KEEP THE ORIGINAL.

OBS crashed. What kind of recording did it leave?

A gaming session, livestream archive or tutorial may fail at a different stage: capture, finalization or playback. The file type changes the next step.

Check the format used for this session

In OBS Settings > Output, check Recording Path and Recording Format. Find the file from the failed session; changing the format now affects only future recordings.

OBS MP4 will not open after a crash

The recording has a file size, but the player cannot read its duration or start playback.

CHECK FIRST

Check the Recording Format used for that session and test the original, not a converted copy.

WHEN TO TRY REPAIR

An ordinary MP4 remains unreadable after interruption and still contains saved media.

Recording stops at the same timestamp

A long gaming session freezes partway through, or the displayed duration does not match the session.

CHECK FIRST

Seek to the same point in another compatible player and check whether the disk filled up.

WHEN TO TRY REPAIR

The saved file fails consistently; repair may make remaining media readable but cannot extend past the recorded endpoint.

OBS remux failed

MKV to MP4 remuxing stops, or its output is shorter than the source.

CHECK FIRST

Play the source through the failing point; select a different destination with enough free space.

WHEN TO TRY REPAIR

The source itself also fails. If only the output fails, resolve the remux or editor issue first.

It plays, but will not import

A Hybrid MP4 or MOV opens in a player, while an editor rejects the file or an audio track.

CHECK FIRST

Test the original in a compatible player and check the editor’s format, codec and audio-track support.

NEXT STEP

If the recording plays fully, address import compatibility first. Consider file repair when the saved original also has playback errors.

REMUX OR REPAIR?

MP4, MKV and Hybrid formats need different decisions

MP4 / MOV

Ordinary recording interrupted

A crash may leave playback information unfinished. Keep the saved original; converting an unreadable source cannot supply the missing index.

If the original cannot open, try repair.

MKV

Readable recording, incompatible editor

Use OBS File > Remux Recordings, choose the original and a separate output. If it completes, check the new file in your editor.

If remux fails, check source playback and destination space.

Hybrid MP4 / MOV

Fragmented recording with a finalization step

Hybrid MP4 arrived in OBS 30.2; Hybrid MOV in 32.0. Test the saved file before treating an interrupted session like ordinary MP4.

A readable file rejected only by an editor needs compatibility checks first.

Both audio tracks exist in this example. Select the recorded microphone track in a compatible player or editor.

In VLC, use Audio > Audio Track to try the recorded tracks. An editor may show desktop sound and microphone on separate tracks. If you find the voice there, select or mix that track; if it was never captured, repair cannot add it.

How to Use OBS Recording Repair in 3 Steps

Select the original, run repair and save the available output. Screenshots show the shared video repair workflow.

Find the saved OBS recording

Check Recording Path in OBS Settings > Output. Select the original MP4, MKV or MOV from that session, rather than a shorter converted copy.

Start recording repair

Add the damaged original and start repair. If advanced video repair requests a sample, use a healthy recording with matching encoder, resolution and frame-rate settings.

Preview, download and continue editing

Preview the available footage, then save the result separately. In your player or editor, select the recorded audio tracks and play across the point that previously failed.

MADE FOR YOUR FILES

Turn a damaged recording into footage you can work with

Fixo attempts to rebuild readable video and playback information, helping you return to the gameplay, tutorial or livestream footage that remains in the file.

Saved file · playback unavailable

ILLUSTRATIVE WORKFLOW

The gameplay is saved. The recording will not play.

A crash can interrupt the video index while picture and audio data may remain. Start with the recording OBS actually saved.

Original file

OBS MP4 / MKV / MOV, with recorded tracks

Repair available data

Inspect the saved media and rebuild readable playback information where possible.

Continue with a saved copy

Preview available picture and sound, then save separately for a compatible player or editor.

Illustrative content and workflow · not a measured repair result

Watch the available footage

Access readable moments from a recording that failed to open or stopped playing correctly.

Keep recorded sound in the story

Usable recorded audio can accompany the recovered footage; repair cannot add a source OBS never captured.

Continue the edit

Use the saved result in a compatible editor to assemble the parts you want to share.

OBS Recording Repair FAQs

Can an OBS recording be repaired after a crash?

Sometimes, when usable media remains in the saved file. The recording mode matters: traditional MP4, MKV and Hybrid MP4 do not behave identically after an interruption. Preserve the original and check it before choosing remux or repair.

What should I do when OBS remux fails?

Play the source in a compatible player and seek near its end. If it plays fully, use File > Remux Recordings in OBS with a separate destination and enough free space. If the remux completes but the editor still rejects it, check codec support. If the source itself stops at the same point or has no readable duration, use the original for repair. Remuxing cannot add footage that was never saved.

Why does my OBS recording have no duration?

The player may not be able to read the timing or index information, or the write may have ended unexpectedly. File size alone does not establish how much video can be recovered. Check the playable range and the saved original.

How do Hybrid MP4 and Hybrid MOV change the repair path?

OBS introduced Hybrid MP4 in 30.2 and Hybrid MOV in 32.0. These modes write recoverable fragments and finalize the container differently from ordinary MP4/MOV. Check the mode used for the failed session, test the saved original and follow OBS guidance. A readable file rejected only by an editor may need remuxing or codec support rather than repair.

OBS recording has no audio or only desktop sound. What should I check?

In VLC, open Audio > Audio Track and try each recorded track; in an editor, inspect all imported audio tracks. If another track contains the microphone, select or mix that track. If OBS never recorded it, changing settings now or repairing the file cannot add the missing speech.

Should I convert a damaged OBS recording before repairing it?

Keep the original recording as the repair input. Conversion requires readable media and may create a shorter output or leave out a track. If the original already plays correctly, remux may be the right compatibility step instead of repair.

What are the free repair and download conditions?

Review the allowance, preview and saving conditions shown by the online service before processing. Downloading the desktop installer is separate from its repair and saving license.

OBS Recording Repair Case Studies

A match highlight, a recorded lesson or a workshop replay: follow OBS recording problems through to the footage people need for their next edit.

Ranked match highlights

Recording stopped in a crash

"My PC crashed just after the final round, and the OBS MP4 would not open. After repairing the saved file with Fixo, I could use the winning play in my highlights edit. That moment was the reason I had recorded the match."

A local OBS recording was not finalized when the computer stopped. The match footage remained in the file; the creator used desktop repair for the long recording and checked the key sequence.

Recorded lesson

Playback froze halfway

"The lesson froze just as I started explaining the difficult part. Fixo made that section playable again, including my narration. I could finish the course edit with the original explanation instead of recording the whole lesson a second time."

The saved OBS lesson stopped at the same point in compatible players. The needed explanation remained after that point, so Maya checked the repaired segment together with its narration.

Workshop replay

Speech out of sync

"The workshop replay showed each demonstration before the presenter explained it. After repair, I could follow the movements and the narration together in the sections we needed. That made the recording useful for colleagues who had missed the session."

The local OBS file contained both the demonstration and recorded speech, but their timing was damaged. The producer reviewed representative steps before sharing a separate repaired copy.
