I'm trying to do some matchmoving and need to create a camera with the same attributes as my real world video camera. Anybody know where I can find the correct camera attribute values for a Canon ZR500 miniDV camera? It says 2.6-6.5mm and 1:1.8 on the outside of the camera, but I'm not sure how those numbers relate to the values in the camera attribute editor. THANKS!

I believe the focal length unit is millimeters(mm) and the film aspect ratio would be 1.8 for the 1:1.8 ratio

so focal length would be: anywhere from 2.6-65mm, depending on what your lens is.

with a quick google search I was able to find this page which should be useful for you.

another way to manually do it is to pick points on the footage and manually, here's a tutorial explaining it in further detail:
