I want to be able to count (1, 2, 3, 4, etc.) how many times an event occurs in a video, with the number being displayed in the video. My understanding is that I have to change the number each time, manually, in a new Title Clip, but I wonder if there is a faster way? Can I create the Title Clip once and tell kdenlive to increment the number where I want it to?
Short answer is no.
You could use a title template with %s in it, and then put the respective number in the description of the copied title template in the project bin.
See also this section in the Kdenlive manual.
Thanks berndmj, that will do me.
