With strong
diagonal lines, simply compressing the image for JPG will make the
lines jagged. Then it's re-compressed when rendered in Premiere and
I'm sure it gets worse. Pixels are squares so there's no
way to make a smooth diagonal line really. The saw-tooth effect is
"Smeared" in the anti-aliasing by adding median colours around the
saw-teeth... but that does make it less sharp looking and sharpening
the image will make it worse. Plus scan lines, other digital "Enhancements" .... Anti-aliasing might help a bit. when you make the jpegs use very high quality (Minimal compression). TIP: Avoid images with strong, fine, high contrast diagonal lines. Tim Corio wrote: I haven't used Adobe Premier, but I'll weigh in anyway since you haven't got any response yet. This sounds like a problem with the application resizing the image. Look for options for "anti-aliasing" or "resampling" or some variation on these terms. Hopefully this can get you going until someone who actually knows what they're talking about can advise. Good Luck, Tim On Sat, 2009-09-05 at 22:35 +0800, Elson T.

More so if the lines are diagonal. When the photos are blurred, the jittery effect decrease, but at the expense of reduction of sharpness of the entire photo. All the photos are jpgs. I read a discussion about a similar problem but the date is old: http://www.videoforums.co.uk/adobe-premiere-premiere-elements-after-effects/10791-adobe-premiere-6-5-jpeg-asf-help.html Anyone in the list has same experience? What is your solution? Would converting the photos to bmp help? I'm not the person using the Adobe Premier, but someone else we have asked to do the work. He has not found the solution, yet, and tomorrow is Sunday. I hope to get help by Monday because the client is jittery himself because of an approaching deadline. Elson |
