Compress muted videos by ~90%!

Compress muted videos by ~90%!

It's very useful for demo videos used on softwares/SaaS websites. This simple command is what I've been using to make all of my videos on and

ffmpeg -i input-video.mp4 -vcodec libx264 -crf 28 output-video.mp4

(You need to install ffmpeg first)

Here is the before & after. Judge for yourself:

Before: 9.8MB

After: 0.97MB

You can adjust the -crf 28 parameter for even small file size, but I find the video quality start to decrease dramatically after 28.

Other useful ffmpeg commands to make demo videos:


ffmpeg -i input.mp4 -filter:v "setpts=0.75*PTS" faster.mp4

Get the poster image (first frame of the video):

ffmpeg -i input.mp4 -vframes 1 poster.jpg -y
