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)'

Output:

2.000000
2.500000
3.000000
3.500000
4.000000
4.500000
5.000000
5.500000

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.
