Tips for tracking 3d geometry inside of PFTRACK, please

#1

Hey guys and girls im currently trackign a 3d milk carton in pftrack. The 3d object tracks really well for the first 150 frames and then it tilts forwards and backwards out of control. I was just wondering if there was any tips or advice that could get this to work.

the footage isnt light up fantastically and the the actual highlighted points where the track is aimed at is blurred do these things effect the performance of the track itself?

Any tips on what i need to start with before placing the 3d object into the secne would also be brill. thanks

I forget where exactly, but you can make changes to the footage inside pftrack. I would add some sharpness if ur film is blurry and also play with the levels to bring the highlights down. Also add some user tracks, dont rely solely on the auto tracking features
