Yes, framerate. Please, could you make a little bit of effort so that this
can be a two-sided discussion?

The following command produces a 40-FPS Matroska file, and the next one
transforms it into a 25-FPS file:

ffmpeg -lavfi testsrc=r=40:d=10 /tmp/in40.mkv
ffmpeg -i /tmp/in40.mkv -vf setpts='N*40' /tmp/out25.mkv

Therefore, as far as I am concerned, this setfps filter is only useful
because you did not correctly understand what the setpts filter can do. If I
am wrong, please elaborate. NOT JUST ONE SHORT SENTENCE, thank you.
