Did you capture video using Premiere from a DV camcorder via firewire?
Select the clip in the timeline and expand Motion in the Effects Controls Palette…is Position 360,240 and scale 100% and anchor point 360,240?
Suspect two keyframes stacked almost together…try zooming in on the timeline view of the Effects Controls palette.
Detail the position value and timecode of each keyframe so we can duplicate.
Rendering for preview should involve just hitting the Enter key with your master sequence open…but that takes forever and duplicates preview files rendered in individual sequences. I do typically do nothing to a master sequence but assemble the other sequences.
Why use Premiere to render stills? How do they appear when viewed on a TV from Premiere’s timeline?
Also suggest using the appropriate NTSC or PAL preset in Photoshop for correct resolution. Use 230.230.230 for text color and turn off anti-aliasing in PS.
It is nearly impossible to make bad looking text (on a TV) in Premiere’s titler.
DPI is only an issue with printing on paper. Computer monitors and TV’s just work with pixels, height and width. In Photoshop, use the NTSC or PAL preset that matches your project settings.
