"tracing" stroke effect
on Jun 15, 2013 at 12:06:33 pm

Hi, I got a layer that consists of a bunch of masks which are just basic lines.
There is a stroke effect on the layer and I animated the end parameter to make it look like the line is drawn over time.

Now I am trying to "attach" a shape so that it moves along with the "completition" of the line that is drawn. Sorry I don't know how to say that in a better way.

Does someone have an idea how to accomplish this?

Open up one of the layers with a mask you would like to follow, and open up the mask and click and highlight "Mask Path", (Cntl+C) to copy that path. Now open the layer you want to follow the stroke and open it's position property, click/highlight and (Cntl+V) to paste the path into the positon. AE will create roving keyframes that will follow the path. If you need to adjust the timing, just grab one of the end keyframes, and move it and the middle ones will adjust to follow. If you want regular keyframes, select them all, right click and un-select roving keyframes.

Depending on the size of the layers, you many need to adjust the starting position of your layer. The quickest way to do this is by adjusting the anchor point of the layer. Once you do that your layers should match up.

Thank you John. It's working partially. I guess I still didn't correctly understand a part of your solution.

Here's the problem:
Like I said there are several masks (lines) on the layer. The stroke effect "reveals" all of them one by one.
Right now when I copy the first mask path and copy it into the position of the new layer it spans the "animation" over the time that it takes for ALL the masks to be revealed in the original.
I have 36 masks on my source layer which reveal over a time of about 4 seconds one by one. After copy/pasting the first mask path, the timing for the first movement is spread out over the complete 4 seconds. (Same if I deselect roving)
If I got it right, i now need to manually adjust the timing by moving the last point.. the result is not good.

Could you please tell me if I just did something wrong or if this is indeed the intended solution

If I got this, you don't want to deselect roving, just un_highlight all the roving keyframes, then grab the first one and move it to when the stroke starts. Do the same with the end keyframe and match it to when the first stroke effect ends and you should be good.
