Hello  
I'm a newbie in matchmoving and so this is the first software im trying to learn.I bought a book called Matchmoving the art of invisible camera tracking.And the book is very good.But i have problem.which is when i exported my camera back to maya.the camera is very small and the locators are also small.when i try to scale them.The whole thing gets very big.But when i check the actual book scale.the camera is pretty big according to the scale of the image plane.How do i make the camera big?is there a setting in matchmover that i didn do correctly?tnx  

Hello,
 
You can change the scale of both the camera and the nulls either directly in maya (you can group all what MatchMover exported under a null and simply scale this null as you want), or by setting a coordinate system in MatchMover. In this case, you simply set up the distance between 2 points, so you can scale your scene as needed.
 
Bye
