Footage is a little green
I did a test shoot today (mid day, clear bright sun) and the footage looks a little green. The auto knee is on and I went into the menu and brought up red and brought down blues in the gamma but it still looks a little green. I white balanced and also set the camera to the preset but it still looks green with both settings. Anyone else have this problem with the varicam? Thanks for all your help.

There are any number of reasons your pictures are green, not the least of which could be a lot of green reflected light from trees and grass.
The most likely cause, however, is that your settings are producing the green. You can’t just go into the VariCam menus on location and start manipulating things without suffering the consequences.
There is NO substitute for proper setup with charts and scopes and a qualified tech.
If you absolutely must shoot without a proper setup, it’s probably best to use the factory defaults and trust the colorist to bail you out in post.
Good shooting!

First of all I doubt your monitor was calibrated properly which is the root of the problems you are seeing.
Not only does blue check need to be done but the gain and bias adjustments need to be done to verify the monitor is actually producing white and black properly.
Do you have a waveform monitor available and a dsc chart to confirm if your camera actual does have a green color bias.
Without first confirm which piece of the chain has the problem it is impossible to determine what is causing the problem or if it is indeed a misaligned Varicam. The problems could range from preset gains being off, white shading lens alignment, monitor gain and bias adjustments etc etc.
Does the facility or owner you rented the Varicam from have the necessary test gear (ie waveform, DSC chart, camera black out room lab) to setup a proper baseline reference for the camera. Until this is done all bets are off.
Listen to Leo and myself and hire yourself a properly qualified video engineer to set up the camera and or monitor so you are not chasing your tail out in the field.
The money will be well spent instead of wasting additional money in post to color correct errors caused by misaligned field equipment or operator error.

I recently had this same problem with my camera in Africa. I saw the green especially in the darks. To fix the problem I reset my camera to factory settings. Then I earased my setup card and reinstalled my settings on the card.
This did the trick. I am not a big advocate of going into the menu and changing gamma settings. Any way write back if you need more advice.
