Hi,
I also have problem with motion tracking. I import jpeg sequence in Mocha, aspect ratio is 1280*720 fram rate is 23.976 i track the footage and export it in format After effects transformation data (*.txt), in After effects when I create new null object and paste tracked data from mocha…its does not go well. Null Object moves here and there and Tracking does not work..my aspect ratio & frame rate is same as Mocha… also I have precomposed layer in after effects… but still it does not work …any suggestions! please….
