Or use the standard pixel tracking to set up the corner pin.

<p>First post here! Apologies for any mistakes!</p>

<p>I have a footage of a rotating iPhone with its screen set to green (so I can play around in AE with what to show on the phone screen).</p>

<p>I have tried to manually place my own footage on the screen ( since it's only 30 frames) but of course, that doesn't look good as there are a lot of shaking and inconsistencies.</p>

<p>I tried Mocha in AE but that too doesn't work that well considering this phone rotates in 3d and it's not linear 2D movement.</p>

<p>Tried 3d Camera Tracker in AE but it fails the analysis never succeeds and fails (and IDK why :| )</p>

<p>Attaching required screenshots here. Any help would be appreciated!</p>

<p>Thanks!</p>
