One of the things I noticed about his style is the fact that he mixes a walk-through style with a cinematic style. I realized I don't think I've seen this before.
Walk-through style is where you basically walk-through a home with the video camera on a stabilizer that removes the undesirable camera shake and movement caused by walking. Learning to use a stabilizer takes a good deal of practice.
A cinematic style is where the camera is fixed to a tripod, slider, dolly or crane and camera is smoothly moved on these devices. This is the style we are all used to seeing at the movie theater mainly because Hollywood style video cameras are all so big you can't just carry them around by hand like a DSLR.
Most real estate videographers tend to use one style or the other and don't mix them. Probably because of the investment in time and gear each technique takes. In fact, from what I've seen there's a bit of a techno-religious separation of videographers based on the technique they use. Michael is the only real estate videographer I've seen that mixes both in the same property video.
Which techno-religion are you? Walk-through or Cinematic?
