Jerky Horizontal Pan
I have a super simple horizontal pan of water bottles psd files. There is a jerky movement while they are panning. I tried using just a camera, parenting, motion blur and I still get this jittery animation. Is this a normal problem? Is there a solution to stop this jittering movement? thanks

Where are you seeing this jitter? In RAM preview or the render?
If it’s the render, check your field separation in the render settings. Not sure if you are using NTSC or PAL, but if you are rendering for video, you need to set the appropriate field separation for your standard. NTSC is lower field first, PAL upper field first.
RAM preview by default is unable to do this, and you’ll be unable to see any field separation unless you install some 3rd party plug-ins.
Although AE has, from what I understand, 65,000 levels of subpixel interpolation, sometimes it doesn’t quite look smooth even with all of this set correctly. There are expressions to fix this.. which I can’t seem to find right now. I’ll post them when I find them.

I’m seeing the Jitter in the render and in the Ram preview. Its as if the pan is moving smoothly then hits a bump or two on the way every sec or so. I would be using this for NTSC. I feel stupid but I’m not sure what you’re talking about when setting the appropriate field. I’ll try and search some things for expressions but I’m just wondering why this is such a problem when its a simple pan. Thanks man

If it’s a simple bump every few seconds in the render, it really might be as simple as your computer choking on the playback.
In your RAM preview, show the Info tab by going to Window>Info. It should show your playback speed in frames per second. If you are previewing less than real-time, it will warn you.
As for the fields.. Perhaps I spoke too soon. Field separation in NTSC is only if you are playing this out through some sort of video hardware… like a Black Magic card, or Aja IO. But to explain that..
Add your comp to the render queue (Composition>Add to render queue). In the render queue, click the field next to render settings (it probably says ‘best settings’ or ‘current settings’). In that window, there is a Time Sampling section with a Field Render setting.

It definately isnt my comp chokign up. its just a 15 mb render. I’ve played back 1 gig renders QT renders just fine. I’ve read some posts talking about this says I should add other stuff in to trick the eye to not see it. Something AE is doing to the movement that it just bumps. I’ll try to deinterlaced settings. Thanks

Jetle,
I had the same issue except with a horizontal camera fly-by. I found that if I adjusted the speed and added motion blur to the background and jittery layers, it smoothed it out a bit.
What did you end up doing?
Best,
Tobin
