I’m watching this video: https://youtu.be/2VujUm6K-IU
At times he is working with his hands with the camera directly on front of him while using both hands to work. The camera never moves or gets bumped. In one shot he is hitting something with a hammer. Is he just hugging a tripod carefully? Using a boom? I’m scratching my head.
I’m guessing over-the-shoulder tripod with a telephoto lens. You could also place the tripod between your body and hands, but the wide angle lens needed for that shot would distort much more than in this photo. However, the distortion can be corrected with software.
