I’ve made a tutorial for taking footage straight from your phone and exporting out a tracked camera with little to no effort using CamTrackAr. I then explain how to import it into Blender, project the footage onto geo to use for interactive lighting. From there, things get wild as I move on to Blender then 3dsMax, but the first half of the video tutorial will get you everything you need to take the concept and apply it to your projects. Check it out and let me know what you think!
