Auto color correction
This effect compensates for incorrect color balance in your video. The idea is similar to the “white balance” setting on a camcorder.
Brightness: Color correction may affect the brightness of the image. You can apply a manual correction, if needed, with this slider. (Technically, the control modifies the “contrast gamma” of the image rather than its actual brightness.)
Note: The Auto color correction effect may introduce video noise into the clip as a side-effect of processing. If this happens to a troublesome degree, add on the Noise reduction effect described below.
