I've had problems (and long render times) with large images in AS pro so I wrote this to make my life easier.
It gets the camera information between the in and out point of the project and gets the camera values from every frame, not just the key frames. This is done for maximum accuracy and it's like when you track a layer in After Effects.
I haven't tried anything too advanced yet, but it seems to work.
The left image is animated in AS, the right is a still frame in After Effects with imported camera motion.
Here's an example of using the script:
Let's say I want these two characters standing on piles of money with the camera moving.
I render out the animation with the characters as PNG files (I want a transparent background) and export the camera movement to a text file.
In After Effects I import the rendered frames and Import a high resolution image of the money (that I scale down appropriatley for the scene).
If I look at the animation right now it looks like this:
But now I set the image layer to 3D (the layer with the guys should NOT be set to 3D as this layer already has the camera movement rendered).
And then create a camera.
I go to the text document with the camera movement (the one exported from AS) and copy the text inside.
I select the camera layer in After Effects and paste (Edit-paste or CTRL+V)
And there we go.
Of course you could add several other 3D layers and arrange them in 3D space and build an environment that way.
You can also import Illustrator files in After Effects, just make sure to click 'Continually rasterize' so you can scale it without getting a mess of pixels.
Note: When pasting keyframes in After Effects they will start from the frame you are on at the moment, so it doesn't matter if the keyframe data in the file starts at some other frame.
