  Alexa Mini LF w/Cooke Lenses | Camera Tracking without Metadata

  Posted by Mike Sevigny on December 30, 2020 at 6:17 pm

  I’m attempting to track Alexa Mini LF footage with Cooke Lenses without the metadata (*.dat) that is usually provided with this setup.

  It was shot as ‘LF Open Gate ProRes 4.5K’ (4480 x 3096) with a x2.0 anamorphic squeeze. Lens info was also lost but I know that they were all Prime Cooke Lenses (still some guess work on that front). The sensor should be 36.70mm x 25.54mm but I’m not certain about the crop factor given the above setup

  My intention was to use PFTrack to track the camera but it doesn’t have any sort of Preset for Cooke Lenses, those were dropped and replaced with idata (metadata) imports. The production is willing to pay for a different solution that would solve the problem.

  I’m wondering if anyone has had to solve for this or if there are solutions out there that I’m overlooking. Any help would be greatly appreciated.
