  How use Mocha to track and rotoscope the faces and then apply blurs or smears to the face element?

  Apply the tracking data to a null object and use that to drive the location of blurs/smears.

  If you can send me all the process what you do and how you do it step by step, which layers you are using and so….. with screen shots it would be a great. Thank you.

  No.
  I don’t have time to do that. However, there are plenty of tutorials out there on the BorisFX website [LINK] and elsewhere. There’s a fairly entertaining project where Mocha was used to replace the faces of the Golden Girls in a music video and there’s a tutorial based on that that might be useful here [LINK].

  Basically, once you understand how to use Mocha, you apply tracking data to a null and then use that to drive where a blur is. For example, you could tie a circle effect to the null’s position with expressions and use that circle as a matte to reveal a blurred copy of the footage. Or you could apply the Mocha tracking data as a shape to drive a mask that controls where the effect is placed using the compositing options for the effect.

  Note: Mocha AE in the latest release of After Effects (version 16 – often referred to as CC 2019) has had a major update. It is now a plugin instead of an independent app. It’s also GPU-accelerated if you have the hardware for it. This page [LINK] goes over some of the new features.
