I've not been able to find any posts about this in the forum though I suppose there might be... it's a problem I've seen people talk about and now I'm having where Windows 10 does sudden restarts to update the OS with not enough warning to stop an active video recording, and then the video file that could have gigabytes of data won't play.

I'm guessing that the 1-2 seconds of action that follows pressing the "stop recording" button is what is missing from the file, so is there a way to take the existing file and finish it still?

Thank you!

Don't save directly to mp4.

I like your signature at the bottom and how it suits the discussion. If you have a second I'd like to know more about the pros and cons, as I thought MP4 was supposed to be a great container, but I'm all ears and already appreciate your input
 
Can use different container.
If you require mp4 container, such as when using custom ffmpeg, HEVC_NVENC,
try custom muxer setting: movflags=frag_keyframe+empty_moov
This will make the video readable from unclean shutdown, but will often slow down opening of fragmented mp4.

After, can use remux (obs file menu or ffmpeg command line) to convert a slow fragmented mp4 (or anything) into a faster mp4.

There's a yellow warning when you choose mp4 as your container. It does NOT survive a non-graceful shutdown of the recording process.
