Hi There

Is there a way to tell the camera tracker in Nuke that 2 different takes are
using the smae camera and should match on a particular frame?
Here is the situation:

- I have 2 motion control passes that I need to comp together.
- I want to use the first pass as my master take (A). The second (B) one has
quite a bit of bounce in it (from the motion control rig) so I need to
stabilize it and then track it to the master plate.
- I want to use the camera tracker because a 2 points track is not going to
work (shot is too long and it pans around so I can't get a single continous
track)
- I want to get a camera for both takes but I need the cameras to match at
least on one frame (position/rotation/focal/scale etc...)

Let's say that the 2 takes match perfectly on frame 1
So if track my master plate first.
Then I track the second plate but is there a way to tell Nuke to use the A
camera scene as a starting point and track the B plate from there? To be
able to stabilise/track both takes with that setup, I need them to be in the
same world space.

I hope this makes sense. Any suggestion appreciated!

Thanks
jean-luc
