Bézier masks
You can use the Pan/Crop plug-in to create masks using Bézier curves. For more information, see Creating a Bézier mask on page 267.
Fine-tuning masks
Depending on the source material, creating a clean mask can be a tricky exercise. There are a few tools and tricks you can use to fine
tune a mask.
• Solo the track Click the Solo button ( ) in the track list to isolate the masked track. This allows you to concentrate exclusively
on the mask.
• Toggle effects Turn individual plug-ins on and off to isolate effects in a plug-in chain. Keep in mind that the order of the plug-
ins in the chain is important in determining the final composited output.
• Isolate channels Isolate individual color channels in the Video Preview window by clicking the Overlays button ( ). Click
the arrow on the button to select the specific channel to be isolated and whether to display this channel in grayscale only.
Then click the main button to toggle the channel display on and off. The Alpha as Grayscale option isolates the alpha channel
mask and displays it in grayscale. For more information, see Understanding the Video Preview window on page 347.
