About the Display Quality of External Video
The display quality of your video depends on several factors:
Â Whether you have effects applied to your clips
Â Whether your clip or sequence settings match the video output device
Â The video and frame rate options selected in the RT pop-up menu in the Timeline
or in the Playback Control tab of the System Settings window.
Note: The Scrub High Quality option affects playback quality when your video is
paused or when you are scrubbing.
