There are several simple pan effects for image animation:
- pan up
ffmpeg -y -loop 1 -i bgimage.png -ss 0 -t 5 \ -r 1 -loop 1 -i front.png -ss 0 -t 5 \ -filter_complex " [1:v] scale=w=1920:h=1080 [fg]; \ [0:v] scale=w=-2:h=3*1080 , crop=w=3*1920/1.2:h=3*1080/1.2:y=t*(in_h-out_h)/5, \ scale=w=1920:h=1080, setsar=1 [bg] ; \ [bg][fg]overlay=shortest=1[v] " \ -map "[v]" -c:v h264 -crf 18 -preset veryfast pan_up.mp4
- pan down
ffmpeg -y \ -loop 1 -i bgimage.png -ss 0 -t 5 \ -r 1 -loop 1 -i front.png -ss 0 -t 5 \ -filter_complex " \ [1:v] scale=w=1920:h=1080 [fg]; \ [0:v] scale=w=-2:h=3*1080 , crop=w=3*1920/1.2:h=3*1080/1.2:y=(in_h-out_h)-t*(in_h-out_h)/5, \ scale=w=1920:h=1080, setsar=1 [bg] ;\ [bg][fg]overlay=shortest=1[v] \ " -map "[v]" -c:v h264 -crf 18 -preset veryfast pan_down.mp4
- pan left
