That’s a really interesting thought. I’ll look into that.
Again, what’s weirding me out is the part where it always decides to save when I paste a block of text…. that’s just down-right nutty.

Thanks Dave,
I did try that one, but I think I might have mixed the order up (ie – saving first and importing later). I’ll give it another go and see how it works out.

Thanks for your help.
I can say straight away that it’s not a footage issue – the project in question is a motion graphics animation that doesn’t use any footage. I don’t have multiprocessing or Open GL on. The only plugins I’m using are the cycore ones (though I suppose they’re no less susceptible to corruption).
I have tried to work with non-optimised footage before and experienced varying degrees of instability, but this problem is so oddly specific. It seems to happen only with this one project, but doing a save-as to a new project doesn’t seem to help, even on a different suite.
I’m not sure what the auto-update thing has to do with the problem either. Maybe nothing, not sure.
Given its limited effect, I’m not sure it’s worth a reinstall, but if it starts to become a repeat problem…

Sorry, forgot it’s no longer in my sig.
I’m running AE CS4 (9.0.2.42) and OS X 10.5.7 on a 2.4Ghz Duo iMac with 4Gb Ram.
To be honest, it was more of a funny story to tell – I had resigned myself to the fact that it was just too strange an issue to be solveable.

If you’re using 3D layers, you can make a second camera and set its position to be way back so it can see everything.
Just a quick fix that might work.

The way AE does motion blur is not totally realistic, in that it calculates each individual later separately then composites them together. EG – If you take a blue square, place it behind a red square of equal size and animate them flying across the screen, your red square will have a purple tint at the edges. This happens because AE calculates the blur on the blue square, then on the red square and then places them together, allowing you to see the blue motion blur through the red motion blur. Realistically you should never see the blue square because at every point in time it’s being covered completely by the red square.
This can cause havoc in lots of situations, most noticably in Z-axis motion and X or Y axis rotation. It also makes things messy when:
Layers are closer together than the distance they cover within a single frame.
Layers with motion blur enabled interact with layers without motion blur, or with effects that don’t support motion blur.
Layers use roving keyframes, or sub-frame animation.It also can mess with your head if you aren’t aware of the shutter phase of your composition. AE used to default to 0 degrees (putting the frame at the start of the motion blur), but now defaults to 90 degrees. This can be a problem if you shorten your shutter angle to less than 90 but don’t adjust the phase – turning on motion blur will cause your object to lag behind its own keyframes.
And it gets better when you think that nested comps can preserve their shutter phase, some effects can override your native shutter and Masks can be set to have their own motion blur separate to the composition.
So basically, just try to avoid conflicts and keep everything simple, because there is no “fix” for it.

I’m working at PAL 16:9 Square pixels, but I rebuilt it at HD 1080 to see if it made a difference. It didn’t.
The final output is progressive, so no field issues, but regardless, the issue appears in the project prior to rendering. I’m looking at an Apple iMac LCD monitor but I doubt it’s a screen issue – it seems to be specific to this AE project.
Technically speaking, I wouldn’t say it’s “jittery” – the motion is smooth, it’s just creating those weird curved bands you get when fine patterns aren’t aliasing properly.

Little late to the party here, but I’m having the same issue. I’ve even managed to work out at what angle it occurs (at least for me).
Here are some stills that show it. It’s a vector file as a 3D layer that is being rotated back along the x axis:
The shallower the angle, the worse it gets. I thought it might just be a technical restriction on the continuous rasterize feature, but given so many people cannot reproduce it, it might be a proper bug.
Did anyone make anymore headway into this issue?

This might not be the answer you were looking for, but I’ve never had any success doing the frame-by-frame method for the exact same reason. My Best advice is to go back to AE and try the following.
Motion track the offending logo.
Make a small solid that’s big enough to cover it, with a bit of room around.
Draw a mask roughly the shape of the logo and feather it. This’ll probably take some keyframing, but if you can track the scale and rotation of the logo as well, this will cut out some of the work.
Chuck a 4 colour gradient filter onto your solid. Look at your video, and pick four points around the logo (but not on it) that reflect the average colour of the Golf Bag. Track these points (or just follow them manually) and then using the expressions sampleImage() expression, set the four colours on the grad filter to equal the colour of those four points on the bag.
After that, find the right transfer mode for the job, match the grain with the match grain effect and you should have something worth looking at. You could probably use this method to get rid of the jumpy jaggedies too, but this method has never let me down. I recently had to remove a girl’s earing from a shot: https://www.dailymotion.com/video/xbqa1o_earring-removal-fx-detail_shortfilms
Hope this helps.
