There is a pretty good explanation by Sebastian König in his Track, Match, Blend! [this video] tutorial, Part 08 at 14:25.

If you use Automatic Refinement for the focal length during the solve process in Blender then it shouldn't really matter, since Blender will calculate the (more or less) correct focal length for the given sensor size. For the final image it doesn't really matter anyway, as long as aspect ratio and the camera solution itself are fine. But if you want to be sure you have the correct solution by comparing it with real world data, like your actual camera sensor size and focal length, you can fill in those values in the Camera and Lens panels of the clip editor and see if you still get a proper solution. If the automatic refinement calculated something that is way off from the real world data, th

I want to render the depth map of a mesh I created from a 3D scanner. I already managed to render my image and it is nearly fine. However, I also want to apply a lens distortion to my output (the image should appear as if it was created by a camera with certain parameters). All the camera parameters (K1, K2, P1, P2, K3) are known, but I can't find the option to enter them. I already spent quite some time studying the documentation, searching this site, and reading/watching tutorials. However, my settings/properties look quite different than in all explanations. It should look somewhat like this: [LINK] (see How to determine lens undistortion values for motion tracking? [LINK] or Tutorial on

@GordonBrinkmann I hope I don't seem ungrateful. I do have a simple understanding of the relation between sensor size and focal length thanks to this video [this video] , and I have a further sense that your post is touching upon some additional abstraction -- the 'viewport size' -- but it does not make sense to me that what I can see in my camera FOV would change if I have not changed its position, focal length, or sensor size. Clearly, camera matching is more difficult if the FOV changes when the camera doesn't
