Flickering Lines
I posted this in the premiere forum as well, but since I was working in both programs not sure which one caused it so sorry if you saw it in both places.
I have just had a problem and found a workaround, but wanted to know if anyone else has experienced this, and what they did to fix it. I am running CS3 and created a project full of pictures and text, lots of movement but no video. I set up the pictures and put in the movement entirely in after effects rendered out each section and put them in a Premiere time line. So far so good, my next step was to add lines around the pictures and words, I wanted them to have movement so that is why I didn’t just put strokes around each pic. Once I get the effect I want I then render the whole thing to find that my words are looking like they are breathing or pulsing. I can’t fix the problem with simple defielding, antialiasing, and deflickering. So then I just render out the lines with an alpha channel with the plan to lay it over the video with the non breathing words. The lines then start to flicker. I made sure that the settings were continously rasterize and I rendered it uncompressed, when I did a 30 sec (out of 2 min project) everything worked perfectly. So I render out the whole timeline and the flicker reappeared. I ended up just rendering out 30 sec sections of just the lines because that was the only thing that seemed to work.
Sorry for the wall of text but it was very frustrating and I was wondering if anyone else has had experiences like this.
Thanks,

You shouldn’t need to deinterlace if you’re just working with computer generated graphics and text. When you deinterlace something that doesn’t need it, AE tries to interpolate lines that aren’t there. That usually causes flickering for me. Check your interpret footage settings.

I only tried to deinterlace only after I saw the flickering in the final rendered version. And I only saw the flickering after I had put everything together and rendered. After every step I always checked and there was no flickering until the very end.

How about your codec settings (even if uncompressed)? Sometimes they can override your comp settings.

where would I check those??

To avoid fine line flicker during movement I usually turnn on motion blur, and in the composition advanced settings, I have my shutter angle set to 400-450 degrees
