[Cin] Source=ProRes; render=low quality

[Andrea paz]

Hi,
To make a video, I recorded the screen as mkv/h264; then I encoded it
as prores as intermediate and finally I rendered the project as
mp4/x265. The parts of the project that are not derived from Prores
look good; those that concern Prores are darker and above all of poor
quality and illegible writing. Can you tell me why?
