So I spent a lot of time downloading, evaluating a handful of video editing softwares. Most of them are behemoths and absolutely suck the life out of your machine if it is anything less than a high end setup. Mine is a 5th gen i7 with 16GB RAM and a 2GB GFX card, and the thing absolutely dies editing 4K video.
Anyhoo, I used Adobe Lightroom CC (for color grading/LUTs loading) in combination with Movavi Video editor for trimming, clipping, joining and transitioning of videos.
Took a better part of the day for editing and rendering, but I think results for a novice first timer are good.
What programs are you folks using, which is less cumbersome and does not burn a big hole in your pocket?
