why does the message "some data failed to reconstruct" come up when i solve camera motion? Im working on a gaming montage, so what i did was use the dolly camera from Call of Duty Black ops 2 to create a cinematicand recorded it using a Hauppage. Now i followed the tutorial from blender guru https://www.youtube.com/watch?v=CVPcT0dJmoY and at the part of adjusting focal length and sensory width i did not know what to do because the dolly camera is not an actual real camera with camera specs.

  • $\begingroup$ I'm voting to close this question as off-topic because it is asking about the focal length of camera, and is not specifically about blender. $\endgroup$

  • $\begingroup$ Blender related motion tracking questions are more than welcome, but requests for information about the lens parameters of a specific camera is not about blender. Such a question would likely be a better fit on a forum about the video game (in this case), or maybe photography.se in the case of a real camera. $\endgroup$

  • $\begingroup$ You could try on arqade.se, but I'm not sure if you'll have any more luck there. For future reference, it's best to create an entirely new post when asking a different question $\endgroup$
