Noticeable clarity quality between the three mentioned windows. Preview window for timeline is the worst even with Best (full, auto, etc.).

Oddly Preview window looks crystal clear when viewing material simultaneously in Trimmer window.

720x480 4:3 project with stills, but video (SD) similar. Stills typcially 1600x1200+. Can see blades of grass in Trimmer and simultaneous Preview window view. Once in timeline and rendered, no.

Thoughts? Appreciated.
