Hasta La Motion!

I ‘v seen a few tutorials about exporting tracking data from mocha to AE..

but you know, the problem is the whole things go well with those tutorials and the tracking data transfers exactly as the way they should

but for me..it is just disaster .

for example I do a simple track in mocha and save the transform data out of it..
then in AE I choose the Null layer and past it at right frame and right frame rate.. but
the Null object just goes off the position where It should be..

I know that something’s wrong with the anchor point transformation but I don’t know how .. the Null object should follow the tracking data out of mocha and it does but with offset…
I don’t know how to fix this ?

thank you in advanc
