Corner Pin

The BCC Corner Pin filter allows you to map media to a specific area on a
moving object in a media file.

For example, your media includes a moving bus with an advertisement on its
side. You could use Corner Pin to track and replace the advertisement with a
logo.

Corner Pin offers a number of different ways to customize the filter:

• Pin Over Source: Displays the corner pin image composited over the filtered track
• Corner Pin Only: Will display the corner pin image composited over the full sized source image
• Punch Hole: Displays the filtered track with an alpha channel where the corner pin image will appear
• Show Corner Region: Displays the full size corner pin track inside the corner pin region with the alpha chanel outsize the area of the corner pin.
