I have an idea… I don’t know if it is possible, but maybe.
So… We can use filters on video layers (or tracks). But filters put effect on the whole picture/screen of the video.
What about a setting in filters’ properties to make it/them apply only on a part of the picture/screen?
Example… I put a brightness filter on an 1920x1080px video, but I want to adjust the brightness only 640x360px part of it in position from 1000;200 (upper left).
OR maybe I want the filter to apply in an oval/circle, which center is at 960;540 and R1=360px, R2=480px
AND maybe these can have a feather (not a sharp edge) also?
Am I understandable?
