Fix corrupt video files with ffmpeg


I have a video capture device, the kind that records the HDMI output to a flash drive, but maybe because it's not very good, sometimes the videos get corrupted and I can't use them in video editing applications...

I have tried many solutions and software to fix the files. I love the cli commands, so the only thing that worked for me in the end was using *ffmpeg*. You can fix your video files without any problem. Try the following command if you came here looking for a useful solution:

ffmpeg -vcodec mpeg4 -b:v 7561k -qscale:v 2 -acodec aac -ac 2 -async 1 -strict experimental ./video_fixed.mp4 -threads 0 -i damaged_file.mp4

**NOTE:** You can experiment by increasing the number of threads. Check the next article: [FFmpeg Threads Command: How it Affects Quality and Performance](https://streaminglearningcenter.com/blogs/ffmpeg-command-threads-how-it-affects-quality-and-performance.html).

Good luck!
