Making a Round Movie<br />
A feathered, black<br />
mask named “Face-<br />
Mask.ps”, created in<br />
Photoshop.<br />
Using an application such as Adobe After Effects, you can apply arbitrarily<br />
shaped masks to movies. This can be used, for example, to make a round<br />
movie, or any other shape. Furthermore, the mask can have a feathered edge,<br />
making it blend smoothly into the background image when composited in<br />
<strong>WATCHOUT</strong>.<br />
Start by creating a mask of the desired shape. The example to the left shows a<br />
round mask with a feathered edge, created using Adobe Photoshop. Add this<br />
mask to a layer in After Effects, making it appear on top of the video you wish<br />
to mask. Turn off the video for this mask track by clicking the eye symbol of the<br />
track. In the video track, apply the mask as an alpha matte.<br />
Turn off the rendering of the<br />
mask once positioned.<br />
Apply the mask as an<br />
“Alpha Matte” to the video<br />
track.<br />
