Hasta La Motion!

Hello everyone, i hope this is the right place to post this but i am having extreme problems as a newbie with an experimental trial-project that i am doing.

for people who know me, i am one who has started this thread:

http://www.vfxtalk.com/forum/possibl…ng-t17800.html

im not going to go into details jsut yet of that thread, but my problem is that, i have live-action footage of a person’s head which i have tracked well in PFTrack and followed exported that data into 3dsmax, from tere i took a crudely made head model and attached it with the trackers, i was told to go to the very first frame and match the head model to the one’s in the footage, and as i am very stuck on this, i can never get the head model to match properly its head movement and rotations and it always drifts off unaccordantly from the reference footage, see the outcome so far:

I have asked advice from a couple of people, which is to (as from the previous footage i have uploaded with converning results to them) is to take and bring/move the 3d head model closer or in shot, which i have done and the outcome was that the head model was more evident in movement and rotations, but i STILL canot get it to match, nor is it syncronising with the live-action footage’s counterpart, and it is incresingly frustrating me on wanting to do such a simple thing.

i would really appreciate it if sopmeone can help me on this, as i am really wanting to get this over and done with after months on this seemingly easy task (so i can progress on more advanced thins relating to this) that a newbie with 3d interest and small understanding should know how to do so.

looking forward hearing back from you wonderful people 🙂
