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

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.
