Kdenlive, how to use the chromakey effect properly?
Matthew Martinez
I put the video with the greenscreen onto the top, below is the clip, which is intended to shine through the green.
So, I right click onto the top clip, select chomakey among effects, use the color picker to select the green and adjust the variance.
However, to my surprise, the green of the top clip does not become transparent, but everything else.

1) - Right-click your top clip(green screen clip), go to "Add Transition" and select "Composite". This will show up between your clips.
2) - Extend "composite" to the same length as your clips.
3) - Right-click your top clip again, go to "Add Effect" and select "Chroma Key".
4) - When changing the color, manually open the color picker and choose your color instead of using the water droplet tool at the side.
5) - Right-click the next clip to be shown, go to "Crop and transform and select "Crop, Scale & Tilt" to adjust the clip to be shown if necessary.
1Really, that behaviour is if you use the GPU chroma key. If you use the CPU version you will get the blue/green background transparent after selected the matching color with the pipe.
PS: You will get the background transparent, so no need of composite transition after the chroma, simply put the new background video/still in the track under the one you chroma keyed :D
