PAX B
I guess your're not familiar with cameras, so:
- You have lots of light, so stop down the camera, making focus less sensitive
- Turn on the "truck mode" stabilisation on the lens. You have a stabilised lens, right ?
- Shoot 4kP60 and stabilise more in post [production]
Except there is still a need to be as close as possible for better results. What you are suggesting would help the situation a little, but no director would want to be so far away that the hand held shots are un usable in the name of safety.
So close as possible and remain safe, plus what you said is the way to do it if you can not go with a gimbal that is.
