  • Copy and paste keyframes from multiple layers

    Posted by Terje Lundgren on November 5, 2007 at 6:46 pm

    Has anyone come up with a solution yet to copy and paste keyframes from multiple layers?

    I have a composition with approx. 16 layers with reference keyframes that are to be copied and pasted to another composition with the same layers and effects. Adding up to the problem: the keyframes are on an effect to which you cannot add expressions.

    Can it be solved by writing a script?

    You should be able to put together a script that will do what you want.

    The only way I know is to duplicate the comp, then swap in the new layers by Alt-Click dragging them from the Project window onto the selected layer, one by one for each of the 16 layers. This should be faster, but not one click.

    You’ll end up with effects, keyframes, expression, everything.

    Thanks for the fast replies.

    One solution I have figured out is to create all reference keyframes in ie the first 100 frames of the composition. (Render will then start at frame 101).

    If I create new keyframes on the neighbouring frame by clicking the “diamond” for all layers, I can then drag all these new keyframes to the desired position. However, if it is a lenghty composition, navigating back and forth is still time consuming. The neighbouring frame are also in most cases an inbetween.

    I will dig into the scripting solution.

    if going with the alt-click drag method, remember to have the layer you want to swap out selected.

    I’m confused by your response. Can you reveal layers of a comp within the project panel? Also, when I try to alt+drag a comp onto a layer, I get an error. I want to try your response but keep getting errors. Any help?
