Having an INPUT CONTRACT VIOLATION
by Ian Dillon on Mar 10, 2012 at 1:48:57 am

I have AE 5.5 and all of a sudden when I try to copy several pre-comped layers of a comp I get an INPUT CONTRACT VIOLATION error and am asked to save the project as another then it quits. This happens every time I re-open and try to copy the layers.
I've tried replacing the footage with another type file (png to PS) and no luck. I've trashed the preferences, zapped the PRAM, repaired disc permissions and checked disc with utility.
Can anyone help?

Thanks in advance.
Ian.

I haven't heard of that particular error message before. But there are three easy things to try. See if one works:

Turn off multiprocessing. 8 gigs may seem like a lot, but not for AE. Personally, I wouldn't even try to use multiprocessing with anything less than 16 gigs.

Turn off Open GL acceleration for rendering. Adobe employees don't use Open GL acceleration for rendering, and you shouldn't, either.

If you're using stills, make sure they're RGB and not CMYK.

Input Contract Violation? Well obviously your AE has gone on strike!!

But seriously:

You are not giving us enough information. What are the comps, what is in them, and what plug ins are you using?

As for RAM - 8 GB is not enough for useful multiprocessing on a quadcore - I'd suggest 16 at least.

Though Multiprocessing is used only when rendering (including RAM previews), it would not be an issue when making a copy of a layer.

Tell us more, and/or upload the project here.

That error message indicates a badly behaved plug-in---nearly always a third-party effect plug-in.

So, what third-party effects are you using?
