I am having trouble doing a screen replacement in after effects. I haven't had any issues tracking shots from other scenes in the project using Mocha AE but I can't seem to figure this one out. I need to corner pin screens onto computer monitors. They are really out of focus and I can only see two corners of the screens in the shots. The camera is handheld and everything that is in focus is moving.
Whenever I try tracking in Mocha AE I get a subtle drift throughout the entire track. I am a novice when it comes to using Mocha AE
Is there a better way to accomplish this task?
The AdjustTrack module in mocha AE is designed to fix drift and will be the tool to help solve this.
First, I would make sure that you are getting the best track data. mocha AE can track out of focus areas, just make sure to draw a shape around the monitor and any other elements on screen that are moving on the "same relative plane". There are many techniques to getting a good mocha solve and the most important is understanding what planar tracking is and how to take advantage of its power.
