I have a white 960x480px background where I move clips on via camera.
These clips have ugly edges. Partially even higher contrast values can't solve it. The f_vignette filter does something (in contrast to a statement given in an earlier forum post), but not useful for this need.
Do you have an idea how to deal with that?
In general a vignette function could solve that but this function is kind weird. It doesn't handle the edges as it should be the inner core are and what is really aweful the white background (to black) though the white background is at another armed !! video track.
You can see the clip here at my site -> https://radszene.de/equipment/bikes/rose-backroad-gravelbikes_2026/
Suggestion from Andrew-R: May be rendering at much higher resolution will solve it, at expense of speed drop?? (I think ugly edges are due to aliasing?)
I meant the outer edges of the clips which are moved on the white background.
You can see that near the end of the video when the clip is being moved with y-camera down. Then even the top line becomes visible.
How to get rid of tthese lines?
It could be added by the contrast/brightness plugin. The clips don't have a pure white background. That's why I added contrast 10 to equalize all backgrounds without losing too much of information.
I can't say wheter this line is already there before the contrast filter or not.
I know this effect from GIMP making cut edges visible when adding contrast.
