Motion Blur In P2

[kelvin keehoe]

Hi,

 

I was shooting a music video last week using P2 with original lens. Most of my shot are running at 50fps. And shuttle speed at 1/25. I noticed especially on close up high speed, there are motion blur. Can anyone explain what is actually happen? Did I set the shuttle speed wrong? By the way it was the camera technician set the camera as I was not too sure about the setting. For the normal speed footage was good.

A shutter (not shuttle) speed of 1/25 would be the video equivalent of an open shutter. Especially at 50fps. Which would explain your motion blur. You should put it at 1/50 (at 25fps, 1/100 at 50fps) to get that 180 degrees shutter angle look, which I guess is pretty much standard.
