Description Dominik Kummer 2023-10-06 21:16:34 UTC
I do set the background color to tranparent by hand to encapsule video components
into single kdenlive files with transparent background.

Here is a full example that showcases what I basically want to achieve:
https://drive.google.com/file/d/1DOpgqOEGhOQCt00KbRlF-xeELKg2JWTr

Kdenlive components to add as clips into main:
* transparency/transparency_component1.kdenlive
* transparency/transparency_component2.kdenlive
these files I had to edit manually with Kate to replace `<property name="resource">black</property>` with `<property name="resource">transparent</property>` inside background producer `<producer id="producer0" in="00:00:00.000" out="00:05:10.761">`
There should be a Project Setting to change the background color to transparent.

Kdenlive main file:
* transparency/transparency_main.kdenlive
I added the component files into main as clips. But even though the components have no audio tracks, Kdenlive wants to generate an empty audio sequence for each. this makes layered editing cumbersome.

Kdenlive main rendering:
* transparency/transparency_main.mp4
Here we can see that the final transitions are not as expected.
