Hello, in the last few years I have used Grassvalley HQX to render videos in full HD (1920x1080). I recently started filming in 4k and when trying to render using Grassvalley (as usual) the program crashes and I can not render correctly. I have rendered resolutions higher than Full HD (2k, 4k, etc.) using MagicYUV without any problem, but the files are too big compared to what Grassvalley offered me. What other codec can I use? my goal is to render with the least possible compression to upload the video to youtube. Does anyone know what the problem is with the Grassvalley codec?
