by executing :

ffmpeg -i cat.mp4 -framerate 30 -i dem.png -filter_complex "[1][0]overlay=x=100:y=100" -c:a copy -movflags +faststart out2.mp4

How can i scale mp4 in case i know paddings/required height/width of scaled mp4 here?

Very beginner in ffmpeg. I know, i need to use scale param, but can't understand how to do it with my current ffmpeg command.

Maybe someone know how to do it?

This works like a charm :

ffmpeg -y -i cat.mp4 -framerate 20 -i dem.png -filter_complex "[0:v]scale=512x397,setsar=1[v0];[1][v0]overlay=x=45:y=45" -c:a copy -movflags +faststart out2.mp4

Result will be :

If anyone can step-by-step describe what each part of command do - will appreciate!
