Created attachment 103175 [details] Simple Kdenlive project with compositing of a standard clip and MLT playlist When I set clip dimensions in Composite or Composite and transform transition, it resizes to the desired size. In case of using an MLT playlist instead of the clip, it is not resized at all. Other transition properties seem to work correctly. I've attached a simple Kdenlive project showing the bug, comparing a clip above a transition and a Kdenlive project containing the same clip, above the same transition.
Should be fixed with Kdenlive version 17.04
