Feature Request

Hi, i know, the following can easily be achieved with existing functions. But this is a request about speed improvement. I'd like to use filters only on certain regions of the video. for example if i have a video with borders (16:9 -> 4:3, TV-crop, ...) i'd like do something like Code:

AFAIK crop and addborders are VERY fast as they try to not change the actual video data (offsetting only).

Crop does what you want: like WarpEnterprises said it works in-place. (That's why it's so "helpful" in finding pitch/width bugs.) There should be no need to add borders afterward, unless you're making a VCD or similar.
