You can copy (cut) keyframes for Shape Layer paths or Mask Paths using the same set a keyframe and cut technique, then paste them directly to the position property of a null or any other X,Y position property by simply setting the first keyframe and pasting. The technique he uses will not follow curves very accurately, but your design may not require that. Use the Search Help field at the top right corner of AE to find out how to setup and use trim paths. As long as the original shape layer was not repositioned, scaled, or rotated the paths will line up.Īn easier way to do this may be to use Trim Paths. You can select each path, one at a time, set a keyframe for the shape layer path, which makes sure that you have selected the path, cut it using Ctrl/Cmnd + x, which does not cut the path, just the keyframe, then create a new layer, select the pen tool, click anywhere, and then paste using Ctrl/Cmnd + v. Shape layer paths are not masks so you can't use the Stroke Effect with those paths.
