Subject: Tech: ffmpeg-selective mp4 volume increase
A command for increasing the volume of mp4 video is:
ffmpeg -i input.mp4 -vcodec copy -af "volume=3dB" output.mp4
This would increase the volume of the whole video by 3db
What would be the command to increase the video's volume by 3db between 24 minutes and 30 seconds and 30 minutes and 10 seconds only?
