Question / Help Recover MP4 Files after Crash

[docmatrix]

Is it at all possible to recover the locally produced MP4 files if OBS crashes before building the MP4 at the end? I have several recordings I would really like to keep, however OBS crashed and only left me with large files that don't seem to be readable by any standard video players (VLC / GOMPlayer)

Many thanks!

Hey doc!

Have you tried repackaging them as FLV files using something like ffmpeg or SUPER?

I know that if you have OBS set to save the recording as an FLV, I don't think it has this problem, and changing the container from FLV to MP4 is really fast with ffmpeg, since there's no new encoding to do. So in the future you might want to consider saving as FLV, just in case.

Although this might be a fixable issue on our end.

Haven't had any luck :(

Tried ffmpeg:

D:\OBS Recording>ffmpeg -i "Stream (03).mp4" -vcodec copy -acodec copy fix.mp4
