3D Camera Tracking Issues
on Jul 23, 2015 at 11:09:16 am


Im having a strange issue with After Effects and I just cant get to the bottom of it. Im using the 3D camera tracker to track some footage in AE then adding a text layer to a group of targets. It all looks fine and matches the shot well.

I then export this with an alpha channel (obviously removing the footage layer) and put it into Premeire over the same piece of footage. Most of the time this works fine with no issues, but on some shots it no longer matches up and no longer tracks with the footage. I just cant work out why! Any help would be greatly appreciated.

It's probably confusion in the the shots you tracked, and the shots uyou didn't. Scrutinize that footage to make sure you got things right.

Also, check for frame rate mismatches.

Why are you rendering just the text out and compositing in in Premiere? AE is a compositing app...why not render the whole thing out there?
