Hello.
I bought Vegas Pro 20. The computer is on Windows 10. I record videos with a Sony 4K camera in XAVS codecs and after editing it saves ProRes 422 in 4K resolution. The image quality is the same as with the source XAVS codec. However, when it saves in a lower fullhd resolution in the ProRes 422 or HQ codec, these are large artifacts with compression. Does anyone know how to fix this problem?
