Kdenlive, how to use the chromakey effect properly?

Question

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.

Solution

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.

I understand your point, I thought maybe I can ask this because there is a kdenlive tag.

I'm pretty sure that is what was already suggested in the accepted answer!
