If you are transferring "on the fly" (in real time) to a NTSC video camera, you will need a 5 blade shutter, as you surmise. When there is no "flicker" in the output from the camera, as seen on the monitor, then your projector will be running at EXACTLY 24 fps.
You should use a projector that is NOT dependant on the mains frequency as this CAN vary slightly; even 0.2 hZ change will show up us a "flutter" in the transfer. If you can find a five blade machine of B&H origin, it should have a preset control for fine tuning the speed; usually this can be brought out on leads so you can monitor, and correct by hand if required , the transfer speed for no flicker.
That would be your "low price" option; crystal controlled projectors would be VERY pricey.
Thanks! That was extremely helpful! Do you have any B&H models in mind because I am not too familiar with which projectors have the capablilty of a 5-blade shutter?
