@twsh i havent actually used it but i was looking at kdenlive. it looks comparable to premier pro. the catch is its not on windows.
im assuming you got the presentation video and the slides and want to keep the audio straightforward and cut between the presentation and slides? if yeah then it should only be a little overboard for it.
@sireffe I haven't thought it through yet. I think I want the video to be of the slides, with my voice (and maybe a video, but me talking to a laptop will be boring).
I will look at kdenlive.
A resting space for the wayward soul.
