Does ffmpeg zoompan filter has a cap for
z value? I tried a simple test that stops zooming up at
10.5. Is it that
10.5 is the maximum value for the
z parameter or is there a limit for maximum frame dimensions?
zoompan=z='print(zoom + 0.5)'

If there is such a limit its worth mentioning in the docs as well as the minimum of 1. That matters when choosing the tool to implement a certain effect.
I wish ffmpeg had some versatile capability of arbitrary zoom and positioning video input without limitations, like in any compositing software.
