When filming in light that isn't evenly white (ie it has a tinge of a certain colour) the camera needs to be told what it should consider truly white. If the white balance is set to auto, and the camera is, for example, used indoors where the light normally has a red tinge, the camera will assess the entire image, determine that red is the dominant colour, and reduce the amount of red in the recording. | When filming in light that isn't evenly white (ie it has a tinge of a certain colour) the camera needs to be told what it should consider truly white.

Consider a very blurred image of something, all the light and dark areas, and all the colours will smear into a uniform colour of a certain brightness, ie it will have very low contrast. By comparrison an image which is in focus will have many distinct areas of different colours and brightnesses. The camera prefers the latter of these two situations and deems this to be focussed. | ||
If you're filming in decent light, and will be zooming then auto is advised. If you're in dark situations, or the camera shot won't be changing at all then manual focus should be considered. | If you're filming in decent light, and will be zooming then auto is advised.
