Kdenlive-25.2.0-1.1, suselinux, chromacolor WITHOUUT SAM-2

I got tricked into partly installing some SAM-2 plugin but it seems that it is a ‘meta’ product of which odor I don’t even wanna see a trace on anything within ten clicks of my ranch. Recovering the entire system from a backup image made fumigation unnecessary and I want to remove the background from a clip in the timeline but can’t seem to find the proper ‘effect’ with the color picker.

The idea would be to remove the black background from the simulated neural brain so that the video under it in the timeline can show through. Black has been selected but it isn’t showing through.

i found the answer; the menu path is: >Alpha Mask & Keying>ChromaKey
