Thanks for your reply Dan. I’ve been agonising over this and wasting WAY TOO MUCH time trying to work it out. I was convinced there was an error in my system. Makes perfect sense now that you’ve explained the time offset factor–although I never would have got there myself.

I’ve applied your time compensation expression to the position property of the layer in my nested comp as follows:

C = comp(“Main Comp”);
L = C.layer(thisComp.name);
C.layer(“Null”).transform.position.valueAtTime(time+L.startTime)

I’m getting an error in Line 2: “Bad argument: couldn’t find layer named “Nested Layer”. I can see what’s going on here: it’s looking for a layer with the name of my nested comp // layer(thisComp.name) // inside my main comp (given the variable “C”), which obviously doesn’t exist. Is this correct? Have I mixed up which comp / layer names to insert in the “Comp Name” / “Layer Name” positions?

Dan, you’re amazing. I realise that was probably pretty basic–but it really helped me out and I often see your name pop up with regular help and advice. Nice one.

Cheers

I’m sure this is fairly elementary–but I’m almost completely in the dark when it comes to expressions. Is there a way to link the position value (specifically the y value) of one layer to a slider control so that 1 on the slider is the starting y value (in this case -30), then 2, 3, 4…etc. each increase the y value by 55?

Any help hugely appreciated.

Cheers

Thanks very much for your response.

I’ve been using the footage primarily in FCP, but doing some additional graphics work in AE. I had issues with the sound going out of sync and read on several forums that this was a relatively common issue with the H.264 footage coming out of a 7D. I ended up re-encoding everything to ProRes 422 and that seemed to sort out the sound issue in FCP; I was still using the native H.264 files in After Effects, though. I will plug the ProRes files in there and hopefully all will be well.

Cheers
