Question / Help I can't open my MP4 file!!

[kychan912]

I recorded a video using OBS yesterday, and it can play after the recording.

Unlike the other videos, the this video donesn't have a thumbnail, it used the logo of VLC (Which is my default video player).

Also, the video got around an hour, is it the reason why it doesn't work?

Please help, I work very hard on this video.

Thank you soooooo much for anyone who help!!!

If the encoding process got forcibly terminated, the file is useless.

Maybe save as FLV then after done recording, convert it to MP4.

For me, many hours of recording as MP4 tends to freeze / lockup OBS for about a minute when clicking "Stop", then it responds again. This lockup don't happen when recording as FLV.

I don't think the process got forcibly terminated, I stop the recording manually, and the whole process ran normaly....

Got enough free disk space?

The effects of running out of disk space: .MP4 becomes completely corrupted, while .FLV is only truncated, probably without OBS showing an out of disk error.

What the filesize of a broken MP4?

I think MP4 in OBS may be limited to 2GB or 4GB, anything more might come corrupted, im getting errors, lockups, and corruption when I try to record MP4 over 4GB using very high bitrate.

FLV don't have this limit, I have success of FLV of over 10 GB and over 8 hours from OBS.

Edit: looks like the size limit was a problem on older version OBS. Maybe update OBS if using outdated OBS.

Im not sure if corrupt MP4 is recoverable... Use FLV from now on as I found far less corruption of FLV compared to MP4.

Might be possible to use MP4 recovery tools but I haven't tried any of them.

OBS being unresponsive for a minute after over 10 hours of recording as MP4 still bothers me, not a problem on FLV. Did you close OBS too soon after you click stop recording?

A corrupt MP4 is not recoverable, that is why we recommend using FLV. And then remux it to mp4 afterwards if you really need an mp4.
