Very smooth video editing. I had no problem with editing 4K 30p 100M. I applied random color effects, transitions, text. initial test video was 3min long. it took 15min to render with H.264, 5min with H.265. if you are doing youtube or your own video, there is no reason to go for h.264.
This video is a test editing video. please do not expect for beautiful video sorry.. I got no time for that. I work for Broadcasting, and this ipad mini 5 totally works. only if you know how to use lumafusion.
