Hello,
I was waiting 1 day and 11 hours to finish my rendering, but unfortunately 13 minutes before the end, Windows blue screen occurred. Not ended video file is corrupted (not properly closed video file). Video size is 17 GB.
Do you know some tools (not online ones) which can fix such corrupted video files and let me play it. I will render the last 13 minutes. I don't want to wait one more 35 hours to render the file.
PLEASE HELP ME :(
Regards
Marcin
I'm afraid you are asking for a lot. You could try VideoRedo, a paid solution.
@marcinzm Try this https://github.com/anthwlock/untrunc/releases/tag/latest
It is a newer version then I used, but assuming no bugs in the build should work for you
The reference file it requires is an encode identical format of your corrupt encode, however it was successful
@Former user Thank you for your post. I tried this GUI tool, but...
- video was repaired, but contains errror. The video is slowed down, but the original video wasn't in slow motion. 25p frames was slowed down.
- but good thing is that the video is playbackable
I got the following logs using untrunc:

If audio and video are not in sync, give `-sv` a try. See `--help`

Is it possible to fix the video by changing settings using this tool?
Thank you.
I have only used it a couple of times last year, and in my case it just worked, so not sure how you go about attempting to fix a problem result. Are all the video frames actually there, it's just playing in slow motion, are the frames duplicated?
If you were going to add it back to Vegas timeline, could play it at 2x speed, with another track with your original audio not sped up, and add the last part to the video and encode together, Presumably the extreme slow encode is to do with processing your original clips, and should encode much faster in this situation.. except it looks like you encoded HEVC, which Vegas processes very slowly would have been in a better situation with AVC as far as speed.
There are other tools like shutter encoder that could help, but I could only guess what to do, as I don't know what exactly is wrong with your file. I'd try rewrap, and conform for fast options that may help
