Shows title clip completely covering the video.

When I create a title clip with text only, move it to the library, then bring that clip from the library into a new project, the background of the title clip becomes completely black instead of transparent.


STEPS TO REPRODUCE
1. Create a title clip in the project bin with text only, and background transparent. (Such that putting the clip over another video clip will put the text on top of the video).
2. Move the title clip into the library.
3. Open a new project and add the title clip from the project to the library.
4. Take title clip from project bin and overlay it on video in new project.

OBSERVED RESULT
The title clip acquires a solid black background that completely covers the the video it's overlaid onto.

EXPECTED RESULT
Only the text in the title clip should overlay onto the video. That is, the title clip's background should be transparent.

Library title clips which have an alpha channel doesn’t work, as MLT (the Framework on which Kdenlive are based on) doesn't support alpha channels. The only work around is to avoid title clips as library item.

This works for me on Linux and was probably related to a frei0r bug. That should be fixed in the last Kdenlive 21.12.3. Can you please test again ?

I updated and it looks like that fixed the problem. I'm going to doing a full edit on a video in a day or two to really get a feel for it. Will post back when I do so!
