Mocha Pro AVX plug-in is found in the effect palette. Drag to a clip and launch the custom interface.

Motion trackers often fail when screen reflections and glare compete with the tracking process. In a few quick steps, Ross shows how to use Mocha’s X-spline tools to avoid reflections.

The X+ button (Add X Spline to layer) is used to subtract and cut a hole from the first spline.

To capture the full motion we track with “perspective enabled” and align the surface and grid tools to the edges of the screen.

Inside of Mocha Pro, we can adjust and animate the opacity and enable motion blur for a realistic screen composite.

To create a “screen power off” effect, Ross used the Sapphire Transition Builder effect to combine multiple effects (transform, glow, lens flare) into one simple timeline effect. By stacking the original clip (with Mocha Pro effect) on V2 and the insert clip (with Sapphire transition) on V1, we can channel the V1 section of the timeline with edits and effects into Mocha as the screen insert.

Beyond planar tracking, the Mocha Pro 5 Avid plug-in can be used for screen inserts, masking, object removal, image stabilization and more. To learn more about Mocha Pro or Sapphire plug-ins for Avid Media Composer, visit:
