Hi,
Does zoompan not work outside the range 1 .. 8?
I want to generate an overlay to zoom in, have the input png start
small, and grow to half the video size, like from 20 to 320 in width.
Starting the zoompan at z=0.1 does not seem to work.
Also if the first filter was successful, I need to crop it so that it
grows over time. I am having trouble getting crop to adjust based on the
frame number. From my testing it seems n in this case starts at 0 when
the enable between starts, instead of the output video frame number like
the other filters I have been using.
Is there a manual or wiki with more information then at
https://ffmpeg.org/ffmpeg-filters.html ?
Thank you
