I'm looking for an NLE capable of 4k/UHD editing on an 4 core i7-7700k.
I see MAGIX Movie Edit Pro Plus claims to be the first to use Intel GPU AVC/HEVC hardware decoding on the timeline which means it should work with h.264 4k on a Kaby Lake i7 CPU - but I cannot find a video to demonstrate how well it works.
Has anyone here tested it or know where I can see it demonstrated. How many layers of 4k can it playback smoothly with color correction and a few effects? What is the timeline preview quality - HD or UHD/4k??
If it works it will be a revelation for 4k editing software as most require an expensive 8 core GPU plus a powerful graphics card.
I don't understand why MAGIX don't have a video on the Movie Edit Pro home page - or why they haven't posted this video from Intel???? 
Thanks
