    Not the best for now. Don’t know that there is a plug-in replacement. I, (and others I’ve seen) use Commotion for tracking and move the keyframes over to AE. Other good trackers are in Combustion, and Shake.

    However, search the posts for the past month or so and someone created an expression that allows you to do two tracks in AE and average them giving a better result.

    If you want the expression for averaging here it is:

    /expression begins

    apArr = [_______,________,_______ ];
    //Do NOT modify below this line
    numOfStabilizers = 0;
    x = 0;
    y = 0;

    for(i = 0; i <= apArr.length - 1; i++) { numOfStabilizers++; x += apArr[i][0]; y += apArr[i][1]; } [x,y]/numOfStabilizers //end just hightlight the _____ things and pick whip to your trackers

    Thanx for that Chirs. Though I am a little unclear as to what you put into the
    apArr = [_______,________,_______ ];
    part of the script.

    cheers

    just highlight the ___’s and pick whip to the attatch point of each of the trackers. THe expression will do the rest for you. Sorry for the double post I think I somehow hit the submit button twice or something i dunno…
