padding is free compared to zoompan and zoompan wouldn't
know what to show outside of the original video.

Isn't it sufficient to pad first, and use zoompan in a later

Hello,
I want to dynamically (per frame) zoom out/scale down a video below 100% size.
It seems that the zoompan filter would be ideal for this case, but
unfortunately it clamps the zoom ratio to [1,10], that is, it only zooms
in/scales up. Why? And what can I use instead?
Thanks.
