Combine automatic and manual tracking techniques to integrate your effects with live action footage
Screen Replacement is one of the most common VFX tasks you'll come across. Sometimes it can be taken care of easily just by using a tracker like Mocha or even the corner pin tracker in After Effects.
In this tutorial, we'll look at a more complex example and see how we can complete the effect when there are focus issues, motion blur, and obstructions in front of the screen. When these issues come into play, many motion trackers won’t be able to get good results, so we'll do it all with the basic After Effects motion tracker combined with some manual motion tracking.
