Question / Help 9H Livestream MP4 Video Broken?... Can i Fix it?

[Salamango]

Hi... i have a biiiig Problem. My OBS broke down in the Stream (4 Time idk why), and i stopped the Recording, but all Videos with the OBS Crash are Damaged. I cant Open it in VLC, WMP, Vegas or anything else. I Try to fix it with a Test Vision of Video Fixer.

So i can Play it after the Fix but the File is Totaly Broken after this... Did OBS Broke down the Files so hard, just becouse it have a breakdown? Only the End (1-3 sek) should be Broken and even if its 5 mins at the End i can Handle it, but from 9H of Recording i got like 1,5 H of Working Files.... Thats... BAD Pretty bad for my Youtube Projekt.

I Uploadet 1 Broken small File so Maybe you have a Tip how to fix it? :( And a Logfile i Uploadet aswell. OBS say 0 Issues.... but you see it...-.-)

MP4 files are generally not recoverable if they're corrupt. This is why you should always record to a resilient container format like FLV; if OBS crashes or the recording is otherwise interrupted unexpectedly the FLV file will usually be fine, while the MP4 file will be lost. If you require a different container format for editing you can remux the FLV file into something else later.

Sorry, no. It's a pile of digital garbage now. There's no way to repair an OBS-created MP4 recording that was not finalized properly. Even (very expensive!) MP4 recovery utilities will at-best be able to grab short snippets of video, usually playing back at the wrong speeds and with the wrong audio.

It's because MP4 keeps its structural atom at the end of the file; the atom tells how to play back the file, at what rates, and other vital information. If you lose the end of an MP4, you lose it ALL. And there's no way to make a new one with the right values.

Do not record to MP4. Record to FLV and remux it later.
If you crash while recording to FLV, you will only lose a few seconds off the end. MP4, crash and it's all gone, permanently.
