Make sure your start time is the same. There is a pref in Mocha for offset to start at frame Zero or frame 1. AE starts at zero and Mocha numbers starting at frame 1 but this can be changed. You can also just slide your keyframes one frame in AE and it should correct.

Interlaced footage can be an issue for tracking, too. Progressive is always better to hold a good track.

we sent out some QTs to be color corrected and when we got them back I was tracking them for screen replacement - my mocha tracks looked spot on, and then when I used those track in AE - every track looked liked it was playing catch up, I tried multiple times to track and try cc power pin vs corner pin nothing would fix it, and then I looked at the frame rate in AE it showed that they were 29.9625 not 29.97 - once I reinterpreted to 29.97 every track was spot on. I going to have to check with the post house that did the CC - I wouldn't even begin to know how they screwed that up.
