Motion Tracking using Perspective Corner Pin - what I am tracking too partially goes off screen

[roberth23027381]

Hi All:

I am trying to use Motion Tracking using Perspective Corner Pin, but what I am tracking to partially goes off screen and I am only left with 3 points.....is there a way to fix it so it can adapt?

If part of the element being tracked goes off screen, it's usually better to switch over to Mocha AE.

Thank you for your response...how exactly do you install Mocha AE?  I cannot see it in a list of available plug ins....

[Warren Heaton]

After Effects includes the Mocha AE plug-in from Boris FX, which is GPU-accelerated, and Multi-Frame Rendering supported. Use the plug-in to work with complex tracking shots such as shots with motion blur or objects that move off-screen. It displays in the Essentials workspace by default and contains the basic functionalities. To use the advanced features, such as AdjustTrack, select Workspace > Classic after you launch Mocha AE. To learn more about these features, watch this video.

To use Mocha AE:

1. Select a footage layer in your composition and select Effect > Boris FX Mocha > Mocha AE. 
2. Click the Mocha logo in the Effect Controls panel to launch the user interface.

OR

Apply Mocha AE after you select a layer in your composition by selecting Animation > Track in Boris FX Mocha.
