credit roll jitter
I have made a credit roll in After Effetcs in which the text rolls from bottom to top. I render it as a quick time movie, with the upper field selected. This is then imported by an avid editor on to the time line of the show. My problem is that some times this rolls smoothly on air and sometimes it jitters, which looks horrible. I keep the render settings the same everytime. And the editor says he does not change any import settings. I wonder what the problem is. By the way the credit roll has a split screen of visuals on the left with the roll on the right(if that has anything to do with it?)
What is the reason and how can i correct it??? Help please…
Rosy.

Are you saying that sometimes the whole animation works and then other times the whole thing jitters, or in the same animation some of it works and some doesn’t?
And what do the jitters look like? (ie, do they happen every second? does the image jump/tear? does it look like field problems?)
Good luck

the frame jumps up and down. and whenever it does the whole animation does, not part of it. and if it is ok, then the whole thing rolls ok.

So when you play the animation once, it plays correctly for a few seconds, then badly, then correctly … ? All within one play?
The jumping sounds like an incorrect field order, but if it changes field order within one playback …
1. Did you stretch in the output module? That’s bad when rendering frames. If that’s the problem, you should drag your comp into a D1 comp (if applicable) and resize to fit before rendering.
2. Are you at 29.97?
3. Did you try rendering lower field first? Maybe you have the wrong field order, but sometimes the text appears in just the right position to hide it … ?Hope that helps,

I use both Avid and AE and have completely given up on credit rolls. Generally the text is just too small and interlaces upon importation. Unless you get the speed exactly right, it just never looks good. Tell the editor to use the text and roll tool in the Avid, they will look a lot 100% smooth.
