Shutter speed and film transfers? at DVinfo.net

Neill Dela Llana · October 15th, 2003, 01:18 PM

How will a film transfer be affected if I shoot in 24PA with shutter speed high and edit in true 24 fps ? Will there still be motion blur as found on NTSC and PAL cameras shot with high shutter speed?

Or is what I see on the monitor what I get when I output to film? Thanks for any replies!

You should contact the trasfer lab you will be using to see what they recommend.

the higher the shutter speed the less motion blur .. most houses will tell you not to shoot higher then 1/60th unless you are using it for effects...

film camera's running 24fps have shutter speed 1/48th of sec ...

film projectors have 3 bladed shutters that break up the light 3 times for each frame = 72 flashes of light per second - we don't see it ( persistence of vision) ...

your monitor doesn't have the 72 pulses so not sure if viewing same 24fps clip would be same on monitor and big screen ??
i would say they are NOT the same as many complain about the jerkyness of 24fps on a computer screen but never complain about viewing 24fps on the BIG screen at movie theater ( but lets not forget about the 72 flashes) ??
