So recently I’ve been trying to solve the problem with the tracking. and I actually solved it for the first scene by trying to track it in matchmover again! and of course after some more research on the camera we filmed the shots with. And yes, I did try matchmover before milestone 2 but the result came out in such a wierd way so I decided to try to solve the problem with nuke just because the track looked really good there. (before being exported to maya of course).
So, I tried to solve the problem over and over again in Nuke, I tried to change the scale, the rotationaxis, the tracks I choose for the ground plane et cetera in nuke but it always came out the same way in Maya. I even tried to play a little with the camera settings, changing film back size and the focal length just to be able to see if that were the problem. And I did notice that I’ve used the wrong film back size for the camera. I found some good information about the camera on this page:
I must have written down the wrong film back size when we were filming.
I also did some more research on what exactly film back size means and found this page that explained it pretty good:
When I changed the film back size to the proper one and tried to track it again in nuke and then export it to maya. did you think it worked? of course not. I even tried a plugin I found on creativecrash.com for exporting the camera, image plane and trackingpoints from nuke but that didn’t work as well. BUT it worked perfectly in matchmover now when I had the right film back size!
I will try to track the second scene in matchmover as well , and I really hope that it will work.
over and out! – Michaela s
