Shooting in Europe at 24p, need to eliminate flicker

[John Sharaf]

Use 1/50 or 1/100 shutter speed.

or 172.8 degrees shutter, same exposure time just different value that you can see in vf

[Brooks Moore]

How do you set the shutter to 172.8 degrees on the HDX900.
Thanks

[Robin Probyn]

Set to the half setting with the shutter switch on the front on the camera .At 24p this will give you 1/48 = 172.8.This is a great feature on the HDX900,you dont have to work it out in your head !
I dont think the HDX900 displays shutter as angles only fractions of seconds,anytime I,ve used it anyway but not 100% sure.?? even in film mode.

Hi Redflag,

Camera at 24fps with shutter angle of 180

[Robin Probyn]

Ok thanks.That half setting is really a good idea,esp for people like me who cant get it right!

[Robin Probyn]

So if shooting 23.98p in NTSC country 1/48th is correct for flicker?

thanks

[Steve Mahrer]

Red Flag;

No, not if you’re worried about 60Hz lighting flicker. If you’re shooting 23.98 in the US and want to elimitate 60Hz lighting flicker you shoudl use a 144 degree shutter. The math is easy 60 / 24 = 2.5 So 360 degrees with 2.5 = 144 degrees, the correct shutter angle to freeze lighting modulation.

ok thanks.But what is that in fractions of a second?

Thanks again

144 deg shutter in 23.976p equals 1/60th second (AC power freq)
