Anyone using TMPGEnc Video Mastering Works 6 to edit H.265 / HEVC 4k without Transcoding ?

[LimitBreak]

Hello everyone,

I received a promotional email from Divx for their newest Divx powered video editing software, and what got my attention was the claim to be able to edit H.265 natively, and encode to 10 bit 4:4:4 output. Also having support for the newer Nvidia video cards for faster encoding with NVENC than using CUDA.

Anyone used this NLE before ? how was the performance, and what are the shortcomings compared to more professional softwares like Vegas Pro, Premiere CC, Edius, etc.. ? Can it support Luts and color grading ? does it have plugins like the film look, etc.. ?
