I put my green screen back up today and started shooting some tests for the “Combat” music video. I the motor I installed into the model airplane was spinning way to fat to show against the green screen. It was just a blur. <\/p>\n

I added 87 ohms of resistance in series (one 47 ohm + 4×10 ohm resistors) and slowed the motor down. <\/p>\n

\"...<\/p>\n

Now I can shoot against the screen at about f1.8 and 1\/60 and actually see<\/em> the prop spinning. When I bring the plane outside, I will have to kill that resistor bank because it will be way brighter out there. I’ll be at about f1.8 and 1\/800, so the prop will need to be spinning faster to have the same (or close to the same) amount of blur.<\/p>\n

Here is some test footage composited into some time lapse I shot of the sky.
