Hi, over time I've seen strange performance breakdowns in my Kdenlive/MLT projects, where sometimes playback and rendering of a multi-track timeline breaks down to a crawl without a compelling reason (to me, that is). When six clips are composed of each other (using the Qt composite & transform transition), then rendering breaks down from around 15fps to a single frame every three seconds or so. CPU load is negligible, around 16% on a Core i7, so most cores are idle.
I've finally isolated a minimal regression project, both as .mlt and .kdenlive files with a few associated image files, ~400kb in total. melt --version gives "6.5.0", it's from the Kdenlive git master ppa which also has the recent git master MLT to offer. If someone is willing to look into this issue then I'm happy to send my regression project. There is no private data included.
