Question / Discussion sensor system for recording camera height throughout shoot day
I do a lot of greenscreen work for microbudget narrative feature work. The majority of the greenscreen shots are locked off (for economy) and don't show the floor. I'm trying to figure out a way to record the sensor/camera height that's faster than a laser/tape measure for each setup (every minute saved on set matters).
Is there some kind of two device system, where one is on the floor somewhere nearby, and one mounted on the camera rig, that will record the height distance at intervals like every two minutes? Matching up the height reading via time and TOD timecode later is no big deal for me.
I know there's the option of wide angle witness camera off to the side, but I'm hoping there's something simpler.
Hoping someone else has already implemented a system like this or knows of such a device.
TIA
