it's been 3 years since I completely gave up on kdenlive.
I put time and effort to get around the dated and unintuitive UI/UX, but it is too convoluted to do even some basic stuff. and the repeated crashes are too much of a pain to be ready for everyday use.
I tried alternatives such as openshot and shotcut, but they too have a lot of room for improvement. it seems there always a flaw of some kind and a lack of usability for this kind of software.
not taking anything for the time, efforts ad good will the devs put into these software, and many thanks to them for everything. but commercial software benefits from the years of having team of full time employees giving them a serious edge on opensource software for video editing.
