--- Comment #4 from Vincent PINON <vpi...@kde.org> --- Bonjour Vincent :) Sorry for late answer The cropped edges seem to correspond to your bottom image format. There must be a bug in Composite & Transform (I believe it tries to speedup compositions by skipping transparent pixels on top image, seems to mess and skipping void pixels in bottom image) C&T, as all video processing, is done in MLT, Kdenlive is "just a GUI & set of tools" around. However recent Kdenlive needs recent MLT, if you build an older MLT you might break Kdenlive. The file to track is: mlt/src/modules/qt/transition_qtblend.cpp (maybe commit from 2017-01-03: "Fix transparency of pixbuf images", precedes mlt 6.6.0...) However, as a workaround: for just an opacity transition, you should rather use "dissolve", that is made for this purpose. I hope you wouldn't have your bug. (and you could use "Transform" instead of "Pan & Zoom", but it doesn't really matter) Hope this helps! -- You are receiving this mail because: You are watching all bug changes.
