I'm sure they do. What you mentioned is usually called a gimbal rig. They've had them for those giant long crane things you see at concerts and stuff. You can get really good gimbals for your smart phones cheaper now. Amazing tech and it keeps getting better.
It wouldn’t shock me if those were designed specifically for the music industry so the camera people could enjoy the tunes, too.
Hilarious, I just caught that. I bet you could do that now with those things. Woulda saved my butt a couple of times. Hard for me to stay still if something I Iike is jamming.
