An easy way to compensate is to adjust the white point: you tell iMovie which color is supposed to be white, and it modifies the rest of the colors to compensate. Adjust the white pointĪ room’s lighting can often confuse a camcorder into using the wrong value for what it perceives as white, which can lead to video with an unwanted orange or green hue. (The same technique applies to darks, using the other slider.)įigure 1: Adjusting the Levels sliders brightens the image and makes this gray footage less muddy, as per below.Īdjusting the Levels sliders brightens the image and makes this gray footage less muddy.
That redefines which values are the brightest in the image. To correct this, drag the rightmost level slider so that the colors move to the right edge of the histogram. In Figure 1 below, the histogram reveals that the video’s drab appearance is due to a lack of whites: the colors drop down to zero well before the right edge of the histogram, which represents the whitest value in the color spectrum.
Change the option from Cutaway to Green/Blue Screen. Select the video and click on the Video Overlay Settings icon. I prefer to use the Levels adjustments in the histogram at the top of the Inspector. Simply drag the image to match the video’s duration.
