I've just rendered a short clip twice. Once at 1080 and once at 2160. Frame rate 30. Shot on iphone 11. When i play back the clip in Rush, it looks pretty good, mostly sharp. When I play back the rendered mp4 on either my imac or my 27" samsung monitor, it looks terrible. Here are 2 screenshots to show the difference between Rush playback view and the actual mp4. Usually its the other way around with quality! I saved to local drive so kept at high quality save. Is this a bug?
