I would like to add a LOGO to the movie. I use the "Slide" (because I can give a PNG file with transparency). On the path 0 I have a clip from "logo.png". Track 1 and 2 are different clips. Between 1 and 2 have different effects
Unfortunately, the "Slide" can only be between (0 & 1) or (0 & 2).

How to add a logo on the entire length of the film?

Remove the logo from the current project. If the project is done, create a new project with the same project settings.

Now add the project file (yourProjectName.kdenlive) and the logo image to the new project. Drag the .kdenlive "clip" to one track (e.g. 2) and the logo to another track (e.g. track 1), resize the image clip. Add and configure the composite transition between track 1 and 2. Render. Done. Well, save the new project once in a while. ;-)

Aaaahh.. i've tried some month ago too and got lost... that's the way it worked!

WOW!
It really works. The project as a video track and an infinite number of possibilities ...
THANKS!
