Like John said, you're stuck with it, and black & white is the only other option you have. Hopefully, you're a better salesman than you are videographer, 'cause you're gonna have to sell these folks on the idea of a black & white wedding video being better than a color one.

If you've never edited before, now is not the time to start learning.

Depending on who this newly married couple is, you'll be luck to walk away from this with your head still on your shoulders!

Hope they are relatives, forgiving relatives.

Green bad, B&W good

I too assume it is night shot, and B&W is the only option. However, if it really is just a slight greenish tint, then you can use the Color Corrector fX to remove some of the tint. There used to be tutorials on how to do this at this link:

Vegas Tutorials

Haven't been there for awhile, but I assume they are still there.

I had this once where a person shot EVERYTHING with thier Night Vision Plus turned on. It was horrible.

I had to do a LOT of major color correction.

There's no shortcut.

It simply takes a LOT of work. While it will not look perfect by any means, it can look a lot better with color correction. Color curves proved useful.

The easy way out might be to turn it into black and white and stylize it...

i.e. sepia tone, or a blue tone.

The color curves is one good way to do this. The bottom gradient shows you what the results are.

Don't use the sepia tone in the film filter, it doesn't look very good.

Why is everyone so sure that it is a "nightshot" error, and not a color balance issue, like shooting in flourescent lights with WB manually fixed on "sunlight"?

Read his subject line.

CCD imagers are sensitive to the infrared portion of the light spectrum and it must be filtered out under normal circumstances. This is accomplished by using a physical IR filter in front of the CCD. Turning on the NightShot mode involved mechanically removing the filter, slowing down the shutter speed and cranking up the gain. The color information was gone and you ended up with the greenish tint.

NightShot Plus adds color to night-vision video by using a mathematical algorithm to calculate color. I'm guessing that it's a weighted averaging of visible light and infrared. It won't record color in a zero-lux environment, but NightShot Plus video shot in near darkness will be "less greenish" and clearer than video shot with earlier NightShot technologies. There will be some color, but I don't think that there is enough of the original color information in the NightShot Plus footage to be able to color correct and make it look acceptably realistic. The black and white method is probably still the best bet.

My suggestion :) Make sure your night shot is turned off for your next shoot

And next time you notice that green tint in the monitor...

B&W or not, aren't the eyeballs all white like zombies?

"Read his subject line."

Oops.

"B&W or not, aren't the eyeballs all white like zombies?"

Wedding of the Living Dead. I love it. George Romero should do that one next.
