Imported PNG sequence does weird things

Hi,

I've looked around for topics with the same issues, but I couldn't find any, so I've made a new one.

So the scene is a bunch of animated png's and an imported sequence of PNG's (made with AFX). All goes well while working on it, but when I render it, all sorts of weird things happen. In some frames it just doesn't show the png's (sequence), in others it scales the sequence up.

Also, I haven't been able to render the whole scene because AS crashes. I render everything to PNG's as well, I've tried several things like disabling the other layers so it's not as heavy for my comp to render, because I thought that might be it, but it keeps doing it.

Anyone have any other ideas?

Cheers

Macintosh? I remember that there were some kind of bugs in Mac version that produced similar problem.
Which version of AS do you have? There were some free updates to fix that kind of bug not long time ago.
What's the length of the imported png sequence?
-G

No, Win 7 on 32bit, AS 6.1
I've looked up the updates on 6.2 but it doesn't say anything about my problem.
the sequence is 332 frames long (and obviously has alpha)

332 frames shoudn't be a problem at all... what's the image size?
According to the workflow you have described, why don't just export the boned images to a png sequence (with alpha) and then composite it with the other image sequence from After Effects in a external video editor? (or are you using AS to edit the png sequence form AFX?)
Does AS preview the scene properly? (the confilctive frames are rendered in AS properly when use the preview option?)
-G

From your description I can't see what you let the images do inside AS. Anything unusual? Weird 3D rotations? Composite modes?

they are 1920x1200, the eventual export will be in HD
I could do that, but I have a camera movement so I woud have to either track it or redo it in Premiere/Fusion and that could give glitches.
When I preview the frames, it looks normal. But it seems that when I start the rendering and I stop it after a while, the scaling appears in my window as well now, so I think it has something to do with AS screwing the coordinates up while it renders.

No, there's no 3D involved in this shot, just a few bone animations and camera movements.

edit: The sequence itself isn't even being moved, but there is animation rendered in the sequence.
