For the Batmobile shot, it's all digital. I filmed my garage and stitched the images together in Windows ICE. With the resulting panorama, I reconstructed the garage in Blender and did a quick Instagram-story camera animation. Many thanks for the Tumbler model from Blendswap: https://www.blendswap.com/blends/view/79773 I did do extensive mesh editing and material setup since it wasn't ready for close-up viewing. This took about a month to create.
For the second garage, it's a simple test of Blender's VFX and 3D reconstruction from motion tracking. Furthermore, I figured out a way to project and composite CG light onto the background footage. This took about a month to reconstruct and setup. The garage background footage used from this tutorial: https://www.youtube.com/watch?v=kzym73lhmD4
