Hello Shawn and QtCommunity, I am having exactly the same problem. When I load a video it becomes recognized as a YUV420P which reduces the colorspace to 8bit and introduces color distortion. I need the original BT2020 colorspace that the file was encoded in to perform further incredibly fine adjustments. If someone could shed some light on this problem for Shawn and myself that would be great. Thank you -NetR00t
