Animated line effect

Find Edges is the lazy way of doing this.  Although you'd probably have to spend a bit of time with colour correction before and after it.  

Thanks for reaching out.

One way to achieve this is by tracing the edges of the object using the Pen tool. Use Trim Paths to create the animation. Lastly, track the footage so that the path sticks to the edges of the object.

Let me know how it goes.
