shooting from inside a car at night
on Feb 19, 2010 at 7:15:20 pm

I recently got a Sony PMW-EX1 and have a question about shooting at night.
For this shot, I will have the camera on a rig looking out the windshield. it will be out on a road with very little light, and the moon will not be in the sky that night.
When i've done this in the past, i have had the gain at 18 and the f-stop at 1.9. the shutter was set to 1/60.
the video looks fine except for one thing. the headlights are flickering. i think it's because the shutter speed is not fast enough, but if i increase the shutter, the scene becomes too dark.
does anyone know of a good setting to use other than what i described above?
Thanks.

If you car has HID discharge lamps then you may not be able to prevent the flicker unless you can sync the camera to the headlight frequency. Try shooting at 25P/30P. This will give you a slower shutter speed and may help.

thank you for your response.
I'm not sure what kind of headlamps it has, but it's an older car and they seem like just regular old lights.
i'm shooting at 1080/30P.
are you saying that a slower shutter will help, not faster?
i'll try to shoot at 25 as well.
thanks.

If it is an older car then I am not sure why the headlights are flickering if you are shooting at 30P then I would not use any shutter for a night shot. I don't know what your are trying to achieve, but have you thought of using interval record and a 16 frame EX slow shutter. Using these settings you would get the outside bluring past, it's an interesting effect.

Cars lights use Direct Current. They can not flick.
You may try this PP for night:

Many modern cars use HiD discharge lamps which do flicker. But in this case it appears to be something else.
