Thanks for the responses. I have settled on pre scaling to the desired height and then use: ffmpeg -framerate 120 -loop 1 -i /tmp/5Pt7y.PNG -vf "crop=1920:ih:t*(iw-1920)/6:0" -t 6 -y outfilecrop.mp4 The relation between "framerate", "-t" and "t" helps a lot in understanding the behaviour of the command.
