That's nothing more than attaching a piece of artwork, the pencil, to a mask path with stroke applied. You would put the anchor point of the pencil layer at the tip. Then you would draw your mask path and apply stroke. You would animate the stroke so that it would appear to be drawn on. Then you select the mask path, create a keyframe for the mask path, then copy the keyframe. You then select the pencil layer, set a single keyframe for Position and then PASTE. You get a start and end keyframe with a bunch of other keyframes set to rove over time for position. The position of the pencil layer will follow the path exactly. Then you simply select the last keyframe for position and drag it out so that the position of the pencil matches the stroke.
This is really easy stuff. The only catch is that sometimes pasting the mask to the pencil layer will just create another mask. Setting a position keyframe, selecting the keyframe and then pasting will eliminate that problem.
Thank you so much for the specific reply, Rich.
No doubut why you are a MVP on this discussion forum.
I have seen a similiar effect from http://www.youtube.com/watch?v=KO_WmWV87t8
The same technique can be applied? Is there any tutorial for creating this kind of cartoon-like animation?
I would like to create one for my children.
There are dozens of After Effects Hand Drawn animation tutorials on the web. Just google that phrase.
You can use mask paths and Stroke to reveal artwork. You can hand draw the cells on paper and then scan them. You can draw your cartoons in Illustrator and then copy and paste the paths to masks in AE to use the stroke effect. I only have one warning. None of these techniques are quick and easy. When I bid hand drawn animation jobs I usually budget between one and two days for each 10 seconds. This type of animation takes a lot of time.
Thank you so much for your warning. I was curioius about how much it would take as well.
And other After Effects lovers!
Here are some resources that I have found on the Internet.
