I've created an animated stroke that moves along the path of a shapelayer. I've managed to do this by creating a shape layer and draw a shape with the pentool. Then i've went to the options of the shapelayer and added > trim path. This created a nice stroke that animates nicely along the path of my shape. It's possible to change the width of the stroke in general, but is it also possible to change the width of the start and end? See this image -->>>
