Since there are probably some people experienced with ffmpeg here, is it possible to to image zooms with ffmpg that go deeper then zoom factor 10? I can zoom up to factor 10 like this: ffmpeg -i someimage.jpg -vf "zoompan=z='10-on/100':d=1000:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=1920x1437" zoom.mp4 But everything above a zoom of 10 seems to fail. Is there a hard limit in the code for some reason? Some way to overcome this? Or is there another nice linux or online tool to do zooms into images?
