I have an invigorator layer in a comp which is using some tracking data from Maya. When I lay the Invigorator layer over the Maya render it fits perfect....no problem.
I then precompose all of the invigorator layer along with its tracking data and any other layers involved, and then lay that new comp over the maya render...but this time I speed up the invigorator comp and the maya render by say 65%. Now the two layers are out of sync.
To fix I have to use posterize time on the invigorator layer.
