I made 3D tracking, and imported it in Blender through maya. Now I have a camera and a point cloud, which are very small. How to increase their size?

I tried parenting to empty (then scale this empty), but in this case, the camera immediately turns in the wrong direction.

How to change the scale of the camera and point cloud, without re-importing them again?

(I spent a long time with this scene and it is the only successful version of the 3D tracking, I am afraid that I will can not restore it, if I start from the beginning).

Here is blender file. http://www.pasteall.org/blend/35762

There have already set the scene (with this addon - http://blenderartists.org/forum/showthread.php?279329-Copy-Particles-to-Rigid-Bodies - thank TARDISMaker for link), in the middle of the scene there plain, and on it - a very small camera, point cloud, and a few cubes to test tracking.

  • $\begingroup$ The camera motion is baked to keyframes? If that's the case, your only option might be to change the scale property in the scene panel, or track the camera in Blender. $\endgroup$ Commented Apr 23, 2015 at 21:40
  • $\begingroup$ yes, keyframes, as I understand. The main reason for which I need to change the size of the camera is that the physics in a blender does not work well with very small objects. As I understand, there is no auto-tracking in a blender, and in my video is no markers, but the camera pans along the uneven ground with autumn leaves. $\endgroup$

  • $\begingroup$ Yeah, I fully understand what your talking about. It's just hard panning the view with smallish objects. And the funny thing is, is that cycles depth of field works needs real world dimensions to function properly! I don't know of a way to scale keyframes, otherwise, I would say that's it. Blender can track footage without placed markers. As long as there are enough non moving points with enough contrast, you should be able to track it in Blender easily. $\endgroup$ Commented Apr 23, 2015 at 21:58

    $\begingroup$ Is there any chance you could change the scale in Maya? If so, that might be your answer. $\endgroup$ Commented Apr 23, 2015 at 21:59
  • $\begingroup$ @TARDISMaker Thank you, good idea, but I've tried, I've combined the camera and cloud in the group (strl + g) and increases the size of group about 300 times, then like everything was ok, but I think because of that something moves wrong , tracking becomes bad. I will try with another video, and maybe try tracking in a blender. What should I do in Blender, if I do the tracking, and the point that I'm following it goes beyond the borders of the frame? $\endgroup$
