Kdenlive got a major update with a MAJOR new feature - sub-timelines!
It brought some bugs with it!
Made a couple bug reports:
469068 Transparent video does not render as transparent
469070 Project Loads with Incorrect Clips in Timeline
And a feature request:
469071 Import Project as Sub-timeline/Sequence
kdenlive is looking real good right now but of course, every new xx.xx.0 release is gonna break stuff ;; i really should just put it on the "do not update" list until the .1 release is out huh
