I've edited 3 videos so far, two of them was 5k footage and one 4k, the 4k video is not the greatest quality, I'm thinking maybe because it was dark and I had and ND filter or maybe I didn't edit the video properly. An other 2 videos which are 5k, the quality are pretty good. I'll have to share themMy bad, it was "Match Source" at 3.01 of the vid. Take a look at what you can do with the video image later with things like LUTs and effects, with these you can alter a video in similar ways we can edit a photo in LR ( adjust exposure,white balance,contrast,etc) You can also remove noise, crop, pan, colour match and do a lot of other things to give your video a boost. There are actually a surprising number of ways and tools to edit video, takes a while getting used to them all.
