*This page will show features that are only available on iMovie through a Mac.
As mentioned on the Audio page, one option that is available on Mac that is not on an iOS device is Noise Reduction and Equalizer. By checking the Reduce background noise box and choosing the percentage, you can adjust the background level to your preference. The Equalizer is there to boost different ranges of audio depending on your needs.
Color Balance gives different ways to adjust a clips color. Auto adjusts the clips colors automatically removing any color casts and maximizing contrast. Match Color has you skim a clip in the browser or timeline to find a frame that has the look you want to match. As you skim, a preview of the match source clip appears on the left side of the viewer, and the pointer turns into an eyedropper. Click the match source clip to take a sample, and the clip on the right side of the viewer changes to match the color palette of the match source clip. Then click the apply check mark. White Balance removes any color cast after you click part of the frame that should appear white or gray. Skin Tone Balance will remove any color cast after you click a well-exposed part of someone’s face or skin.
Color Correction allows you to manually balance the color in a clip. The color correction controls include a multislider control, a Saturation slider, and a Color Temperature slider.
