QuickTime player in macOS has long natively supported different playback speeds. But in the latest version of macOS—as of this writing, Monterey—QuickTime made selecting different playback speeds much easier.
When you open a video in QuickTime, you’ll notice that in the playback chrome there is a button with two symbols on the right side: > >. If you click that button (not the fast-forward button mind you) you’ll be presented with Playback Speed options of 0.5x (half-speed), 1.0x (normal speed), 1.25x, 1.5x, and 2.0x.
If you want more granular control, you can hit the play button and then click the fast-forward button while holding down Option (⌥). Each time you Option-click the fast-forward button the play back screen will increase one-tenth (1.1x, 1.2x, 1.3x, etc.) all the way up to 2.0x. In older versions of macOS, this was the only way to adjust playback speed. It persists in Monterey, but mainly to give you more precise control.
