I have some experience working with Blender's motion tracking capabilities, but have only used cell phone video that happened to be presets in the camera specs dropdown in Blender.

I am trying to do some motion tracking with a drone video, and really have no idea how to interpret the camera specs.

Was wondering if anyone could help me with this?


Trying to find the: sensor width, focal length, lens distortion coefficients (if required).

    $\begingroup$ You don't necessarily need the sensor width or lens size. Use the preset for a 35mm full frame camera and use a 24mm lens size (as stated by the specs). A bit of google will help you find the info as well: vfxcamdb.com/dji-phantom-4-advanced Sensor Dimensions: 12.8 mm x 7.2 mm (0.504 in x 0.283 in) FOV 84° Lens size 8.8 mm (/24 mm (35 mm format equivalent) $\endgroup$ – user1853 Mar 22 '19 at 16:13

If it helps, there are some presets in Blender for certain cameras. In Properties area. enter image description here

Make sure you are in Object Mode and the Camera is selected. I found this info recently, myself.
