Re: Mattes in Red

Hi,

To achieve this effect, do the following:

• Add the PixelChooser filter to the mask track ot the clip to which you wnat to add alpha
• The PixelChooser output should be set to Alpha Channel
• Twirl down the PixelChooser track so that you can see the PC Layer sub-track
• Add the media that you wish to use as alpha to the PC Layer
• Click on the PixelChooser track to access the parameters i the controls panel
• Click on the Matte tab
• Enable the Use PC Layer Track button - you should now have a track matte

Cheers,

Peter.
