Jerky playback after rendering to .avi
Hi Gang,
I’m working with AE 6.5 in 1920 x 1080 (HD) at 30 FPS, 8 Bit
I have a simple 4 layer animation over 150 frames, where I’m moving into the scene using the -Z- axis. I’ve applied Easy Ease to all keyframes. The background is a sky that moving only in the -X- axis and is not a 3D layer.The RAM preview looks great – but when it’s rendered out to an .avi file it plays back really jerky. It’s jerky in all the axis’s, not just the -Z-. Has anyone ever seen this before? Could this be because of the file size being HD?
I’m running on a Dell XPS 410, 3 Gig RAM, Dual Core processor
Thanks for any help you can offer!

did you tried to rendering it in small resolutions to check up if same problem appear?.
if ram preview is ok, it’s probably codec problem.

No – I’m going to try that experiment today. I’m rendering out with no compression, so I don’t think it’s a codec problem. I’ve always worked at 720 x 480 and never seen this problem before. That’s why I suspect it may be the file size. Thanks!

HURRAY!! I discovered what the problem was!
I was rendering out at no compression. So I systematically applied one codec after another and test rendered until I found the one that works! MPEG4! What I find interesting is that depending on what codec I chose for the output module, I’d get different results – like Cinepac would render smooth motion on foreground items but not background items – weird, huh?
Thanks to all who scratched their heads on this one!
