System information
Creating a mask
1. If you have not already done so, place and position the image or video you want to use as a mask
on the top-level track in your project. For more information, see "Adding media files to your project"
on page 91.
2. Place video files on the tracks below the mask.
3. Ensure your mask is a compositing parent the tracks below are child tracks.
4.
Click the Compositing Mode button on the mask track and choose Multiply (Mask) from the
menu.
If your mask image is grayscale, you're done. If not, continue with Step 5.
5. Add the Mask Generator plug-in as a track effect on the mask track and adjust the controls as
needed to set transparency in the mask track.
You can also use the Event Pan/Crop dialog to create event-level Bézier masks. For more
information, see "Panning and Cropping Video Events" on page 275.
