AE Camera Move Looks Jittery
Hi,
I’m working on a project that requires me to do a lot of fairly simple camera moves on still photos. What I’m noticing is that some of the moves are looking subtly jittery when I render them (I’m using uncompressed renders so that I can see the clips at the best quality). Generally I’m finding that the slower moves are the most jittery, perhaps because the motion blur isn’t kicking in as hard?I’m working at 23.976 and the camera lens in my project is 35mm.
The particular segment I’m testing is just s simple slide across a photo, it’s fairly slow so that you can see the image – not a quick pan. I’ve tried varying amounts of motion blur, I’ve used shutter angles between 20 and 360, up to 40 samples per frame and even tried no motion blur, but the movement still seems a little bit jittery. .
Is there something else I should be considering?
Thanks for the help.

Are you sure your drives can handle the throughput? Render out to a more compressed codec to check where the problem is. Do your clips give the same juddery motion if you step through them frame by frame?

What you are describing sounds like Judder. A forum search turns up a ton of posts including this one.

Hey Guys,
Thanks a lot for the help. From what I’ve learned I am dealing with “judder,” so one thing that I might try is changing some of the moves from horizontal slides to zooms or something else less inherently juddery. I may experiment with Timewarp as well…Dave:
Unfortunately I have to work with 23.976, I thought that that might actually be partially to blame… I guess it’s my funeral. -
Misdirect! Misdirect! Add little detail movement somewhere else! Make them read something that’s not moving!

I’m the Penn Jillette of motion graphics.
Really — we’re stuck with frame rates. Is it too much to expect that there would be a limit on the smoothness of motion? Watch movies, and look at pans. Are they really that smooth? We’ve learned to accept it. Which Bourne movie had “paging Alberto De Piento?” Ultimatum? There’s an aerial shot with some nasty judder right after that scene. Also, the main title to Inside Man (Spike Lee) had some nasty judder. Find some more examples, and the client shouldn’t mind. And if they haven’t noticed it, keep those examples just in case.
