I was trying to rebuild gmic on termux with x11 support, but it requires too much memory..... but may be using gmic on set of images (exported by Cin and then re-imported) can be used as workaround for lack of native transitions of such nature? https://gmic.eu/reference/transition3d.html#top (i think you can try w/o blur first) I also built mlt 7.0.1 (multimedia framework) but w/o python support (so no flowblade). If you know any cool mlt command line I can try to run it here (on my small set of vids). Mlt7 apparently dropped few modules.. so kdenlive/flowblade must catch up with this. https://www.mltframework.org/docs/v7migration/
