I recently built a brand new edit system and on the new build, Kyno will not play .R3D files. It works fine with .braw and XAVC clips, but Red will not play. The thumbnails pop up in a drill down no problem, but the video player is completely black with no audio or video response when playing.
On a previous system, I had this exact same problem, but switching to a NVidia Studio driver seemed to do the trick. This time, no such luck. I tried rolling back my card driver to see if I could find a stable build, but no luck.
