Here’s today’s simple tutorial for how to use masking of video in After Effects. Also consider learning to use the Rotobrush. Have a look at Maria Sanchez’s final post about her project which combines the pen tool image masks and the rotobrush.


Also look at the post from last semester in which we covered masking and rotoscoping. There’s a bunch more about the Confused Travolta meme as well as another tutorial I made.


So I’m still working on the second half of this moment from The Shining. After adding a lovestruck emoji to Shelly Duval’s head, I thought it might be fun to extend metaphor of someone startled in the bathroom while primping.


There’s still work to be done. But I thought I’d share some of the process. Creating a traveling matte so that the trembling hand appears over the emoji is very similar to the techniques described in the video above. But here are a coupe of extra tips and screen shots.

In these two shots you can see how much the position and shape of the mask changed from frame to frame. It’s definitely slow work, but it only for a total of 15-20 frames so manageable.



You should also note that the opacity of the mask is zero inside the mask path. This can be helpful when trying to get rid of the pesky contrasting pixels at the edges of the object your trying to mask. You can accomplish this by creating a feather and pushing the mask expansion in the negative direction. Here’s the settings of the mask for this particular set of frames.


Experiment with your masks’ feather and expansion to improve the blending of the edges into your composition.
