Could somebody please help me figure this out? An actor is holding a lit sparkler and takes a few steps and there is supposed to be a trail of light from the motion of the sparkler. I have a fixed angle rotary shutter so I was considering reducing the motor to 12.5fps for this shot (thus the exposure time is doubled than at 25fps), and then conforming it to 25 in post. I'm just worried about blurring my actor as a result.
any tips or ideas?

Think the numbers through - take some footage with a video camera and analyze the motion (in light) to get you an idea of the factors involved. Have you got any cine examples you're trying to emulate ? (not just stills)
