Zoom 20%

From center-top

ffmpeg -i input.mov -vf "zoompan=z=1.2 :d=1 :x='iw/2 - (iw/1.2/2)'" output.mov

From top-left

ffmpeg -i input.mov -vf "zoompan=z=1.2 :d=1" output.mov

Zoom panning to top left

First we scale it up 10 times, then we increase the zoom 0.003 per second, scale back to original.

 ffmpeg -i input.mp4 -vf scale=12800x7200,zoompan=z=pzoom+0.003:d=1:s=1280x720:fps=30 output02.mp4
