Hi all,
I have a problem with the zoompan filter. The video is jerking around.
This is especially visible when the zoom factor is quite high, as in the
below example, where it varies over 100 frames from 5.0 to 5*1.005^99=8.19
Other question: What's the meaning of the "deprecated pixel format used"
messages, and how can I avoid them?
Thanks,
Michael
