Tracking & replace
Hello Masters and Jedi of AE!
I have some question. Practiced tracking and ran into a problem, It is necessary to replace the image on the screen of the information device. Unfortunately, the low quality of the video was shot on a mobile phone.
I can not correctly bind a new image to the device screen(I will provide an example video)
Tell me what technique you need to use Mocha?! Track Camera or 3D Camera Tracker?!
....confused in tracking and techniques (

Mocha AE, Corner Pin tracking, or Stabilized Power Pin tracking (see tutorial). A good overview of Mocha AE is available here. It's everything you need to know to be successful. 

Camera tracking would be the last choice for that shot because of the moving train.
