Syntheyes and After Effects

I have used Syntheyes to stabilize an aerial video taken from helicopter. I exported the 3-D info from Syntheyes as a .ma (Maya) file. I then imported the .ma file into AE, re-imported the original footage, interpreted the original footage to make sure the frame rate and pixel aspect are correct, then dragged the original footage onto the top layer.
According to the Syntheyes instructions, this is all I have to do, but the shot is not stabilized in AE. What I have is the original footage layer, then 5 null 3-D layers with the tracking info, and a camera layer.
How do I get the original footage layer to pickup the null layers below with the tracker data to stabilize the shot?

Hi,
It sound like you need to use the image processing feature in Syntheyes to do your stabilization. Once you have tracked your shot, and have made sure you don't have any trackers that have gone haywire, hit the "p" key and that will open the image processing window.
Select the Stabilize tab and you will probably want to set Translation and Rotation to filter. Cut Freq. affects how much smoothing is done.
Then select the output tab and save it as a quicktime or a file sequence. I believe you then have to hit the Apply to Trackers button to make sure the trackers in your camera data reflect the newly stabilized footage rather than the original footage. You will then need to export a new .ma file for importing into AE.
The stabilized footage and the .ma file should match and you can then use those trackers to lock object to your ground plane.
