Hi guys. I am having an issue with track matte key effect after updating to 7.01 (OS10.8.4). I used track matte key to do some blurring the faces like everyone does here (V1 = video footage, v2 = copied v1 with gaussian blur + track matte key, v3 = circle with traced face motion). I had no problem doing so, and I exported several sequences as quicktime movies without any problem. Then, after I updated to 7.01 and opened my project, I noticed all the track motion were off for a few pixles. But, this only occur when I only turned on the track matte key effect. I spend pretty much all day to reserch this issue, and I just cannot figure out what is going on here. I would really really apprciate if anyone can shed a light on this problem. Thanks!!!!
