Pre comp changes timing on layers

[chrish20073666]

When I work with all layers, the timing/easing is fine. As soon as I pre comp the layers, they seem to shift in time or possibly the easing goes off slightly.

Any suggestions?

Thanks

Check the "collapse transformation" setting on the new comp-layer.

Having this selected definitely changes something, it doesn't fix it though, just kind of shuffles the layers round a little more. I've noticed when I move the comp around the 3d layers are reacting/moving independently as if the pivot point is moving within the comp – if that makes any sense. I presumed that when I pre comp layers, if I move the comp it won't effect the layers within it?

Sorry if I'm not explaining it all very well...

Are they going off within the precomp itself, or in relation to your larger composition?

Within the comp it's always fine, but when I drag that pre comp into a new comp with different comp dimensions and scale the comp down/up it throws the layers out of sync...

Did you used expression or the pig whip before precomping?

When you activate collapse transformation (let's call it "sun"), the AE "sees" the individual layers within the precomp. When the sun is of, the precomp as treated as an normal 2D image, like all the layers are merged into one.

Can you provide the project file, or an excerpt out of it? It will cut down the time for trouble shooting.

It sounds like your pre-comp isn't the same frame rate as the one it's nested in. Can you go to your composition settings (Cmd/Ctrl+k) in each comp and see if they're the same or not?

That was it! Not too sure why but my frame rate was 29.7 on the new comp I was dragging the pre comp into... Thank you!
