For years I've balanced off the blue sky. I use a DVC-Pro and balance for 6200K. Any higher than that and the video will start getting red. Try pointing the camera at different areas of the sky and balancing. Eventually you will get the color temperature you want. I've found that if I balance in the direction of the sun where the sky isn't as blue, I'll get my 6200K balance. If you really want to warm your video, say for a weather shot, balance opposite the sun where the sky is very blue. Doing this you'll discover that grass is more lush and the sky is more vivid. Of course, flesh tones will be more amber so you'll have to be careful. I keep the balance in the camera's memory on all three outdoor filters so I have the warm balance on cloudy days. For indoors I balance on a light blue 5x7 card I keep in my fanny bag. It balances to 3600K and I keep that in memory, too. Nothing is absolute, though. I do have to white balance if I'm in a room with a mixture of say, sunlight and fluorescent. I error on the side of sunlight, using a dichroic filter and I let the camera adjust accordingly. My reporters love the warm look. It gives them the "glow."
