I apologize for this OT question but I have just finished recording an hour-long masterpiece for my class. However, the volume appears to be really low. I don't know why this happened, but long story short, I really do not want to do this again, so I was wondering is there any software on Fedora 31 that will allow me to edit the mp4 to increase the volume. I doubt that this is that easy, but I still thought that I would give it a try.
ffmpeg is a great tool for adjusting media files. https://trac.ffmpeg.org/wiki/AudioVolume describes only for a .wav file, so here's what should work for yours: ffmpeg -i input.mp4 -c:v copy -filter:a "volume=1.5" output.mp4 That should just the video directly and adjust the volume by 150%. Adjust as necessary.
