>Nope, I've had 60Hz fluorescents pulsate slightly on PAL video. Not terribly noticeable, really. Very slight.
>I know for film I can do the 25fps thing, or go 24fps @ 172.8 >degrees...but what about video?
>Not at all a stupid question...
>You're shooting at 30fps or 60i, so you have to use lights that have NO
>frequency relative to the electrical frequency, OR, if you use=20
electronic lights, use some that have a VERY HIGH electronic frequency, so you don't have to worry about the slight pulsating effect.
>If you're shooting with low frequency lights, that have frequencies close to 50Hz, try to use a shutter at a high frequency (inverse the Light/Shutter at LEAST the triple, i.e. 150hz), and you shouldn't have any problem.
>150hz at 60i =3D 2,5 illumination units per frame
150hz at 50i =3D 3 illumination units per frame
>That's a 1/6 difference. I know it can seem to be a lot in film=20
exposure, but, as it is distributed on the frames, it's really easy to catch back in video. And you can see the result in real time on the monitor anyway

>Wonder if you can go with a 1/25 shutter at 24P with the SDX 900?? (Or >an equivalent clearscan frequency?) Even 1/50 would be a help in low >light.
>Synchro Scan in the SDX900 goes from 1/24.1 to 1/249.7 when shooting 24fps.
