Thanks Luis. Lets say you have four clips of a studio session fro music video. Since each clip has the performer in a different position against the background, the color balance will vary from clip to clip. Sometimes a little, sometimes a lot. You could always start each clip with a close up of a white card I suppose and use that frame to balance I suppose but it would be a hassle. The old version allowed you to copy the color balance performed on one clip to all the others.
Color balance is subjective, easily changed to whatever the designer/director/colorist wants. Just grab hold of the handles and start playing around.
White balance is a completely objective camera setting that should be performed with every major set and lighting changes since dimming and reflectance can change the color temperature or color cast of the scene. Sometimes that can be corrected with color balance controls in post.
You can apply the color correction effect, open the color board and, using the scopes, create any look or color compensation you want (within the limits of the filter) and you can easily copy'n'aste those setting onto any other clip.
In the olden days, we shot 5 seconds of a Kodak Shirley, over some other color standard card, at the beginning of every film scene. After our one-light dailies were reviewed and culled, the film printing lab required the gray card or Macbeth chips to perform their magic.
Regretably, I share our digital age's prevailing laziness and tendencies to believe I can fix any stupid exposure mistake in post. I succeed only about 70% of the time.
