I am trying to edit some 4K HEVC double NTSC footage. Loading into Vegas V20 build 326 and rendering is OK, but the preview is stuttering. H364 files do not have this problem. Can that be changed?
I am running Windows 10 on a system with AMD Ryzen 9 5900X 3.7 GHz (4.8 GHz), Gigabyte GeForce RTX 3070 GAMING OC 8 GB V2 LHR and 2x Corsair Vengeance LPX 3600 C16.
