complex cam output from C4d to AE
I think I’ve pooched myself here.
Often when a client changes something I’ll just add a camera as a child of the current camera to keep most of the move and then just add tweaks to the new camera. And then render the whole thing through that new camera. Thats what i’ve done here, but I’ve also got the original camera with a target tag following a moving null. Add to all that, the original camera, with it’s new child camera (and the target object) are in a hierarchy under a null that also has keyframes.
Null – moving
Camera1 – target tag – moving
Camera 2 – render camera – moving
Target Object- movingAnd just because that wasn’t messed up enough the client wanted the scene to run slower so I’ve rendered at 60fps instead of 30.
Now I’m trying to export the camera to AE so I can do some 2.5 D stuff in Ae and have it match the camera move and renders I’ve brought in. I’ve tried a number of scenarios (we do this all the time with a regular set up and it’s as easy as falling off a log – even with the time base stretch). But with this hierarchy, time base, target object and nested cameras, I’m only getting a section of keyframes on the final render camera in AE and it bears little resemblance to the actual action.
I’ve even tried linking the objects in AE to reflect the hierarchy in C4d but that didn’t do it (and shockingly didn’t turn the camera into a whirligig which I thought it would given all the objects have different keyframes in AE and I thought they would add up to a mess)Whats the protocol for this kind of thing? Or is this all just too much for C4d’s exporter? Is there a way to bake this all down to a single object moving about?

Can you clean everything from the c4d file but the camera? So I can take a look?

Thanks Cassius,
Here’s the stripped down file. I want to have some items in AE be in relationship to the included plane.
The animation is between f 440 and f 625 but I want to render this at 60fps so I get twice as many frames (this way I’m not messing with the curves if I instead stretched the keyframes in the time line.)Its the inner nested cam that I need the absolute keyframes for. I’m also ok with building a heirachy in AE with the separate keyframes of all the players too, but I couldn’t make that work either.

I just realized there are no keyframes on the outer camera. Is it as simple as making a single keyframe for all the values I need in AE for this camera? This camera does bring in keyframes to AE even though it doesn’t have any so I assumed those keyframes would be that outer camera’s absolute matrix with its parents movements and the target movement all rolled in and in world space.
Yes/No? -
I’m sorry about the delay, beeing the weekend and all. I hope this still helps you somehow.
What I did perhaps can answer all your questions. I just baked the inner camera to world coordinates, avoiding any need to parent it in AE.
I’m adding the c4d file with the simple expresso code that I used along with cappuccino to bake it. and the AE file showing that it worked.
If you have any doubts I’ll be here.Cassius Marques

I didn’t went into the FPS matter of your problem. But I’m sure it should be simple. If you’re rendering at 60fps, you should change the project settings to 60fps and bake it as that too. (or maybe just stretching in AE will work just the same)
