I just had a bad idea, tell me if it's accidently good: Is it time saving to like, speed up your music when it's done, then making the video around it, then slow down everything, so it is faster to create the video? then you could adjust things after the "slowdown" (adding frames or making things looks more natural) sorry if i don't use correct terms. I don't know much about editing but i was wondering if a trick like this would be useful if that's the case would be a nice life hack
you could accomplish the same thing by just doing the video at a much lower frame rate. but that would look a bit more like a slide show, and any method of 'fixing' that would pretty much take at least as long as the video would take anyway, and probably much weirder and complicated than just putting the actual motion there the first time
