Potential newbie question but i'm having a tough time finding a way to map a screen onto a hole in some footage because the footage is very low contrast and i can only see 3 of the 4 corners. I'm fairly new to Nuke and would appreciate any guidance or pointers.
I've tried the PlanarTracker and it really can't hold the track, i've experimented with the settings but not been able to get a solid track from that approach. The 2D tracker seems to be able to track a little better with lots of keyframing help but i can only get 3 corner points and a Corner Pin needs 4. I tried offsetting a 4th point elsewhere on the track but the cornerpoint node seems to ignore the offset value. It strikes me that with 3 points and a rectangle that ought to be enough. Is there any way i can apply the 3 points to a 3D card perhaps? One of the tasks i need is to recess the image a little, so a 3D solution would be useful. the shot isn't moving enough to do a 3D Camera track either. So with 3 tracker points what sort of approach could i use to get that in 3D space or a corner pin? Really appreciate any ideas cheers Paul
