How long common video and audio lengths take at 1.25x, 1.5x, 1.75x, 2x, 2.5x and 3x speed. Linked times open a detailed page; for any other length use the playback speed calculator.

Length at Each Speed

Times are h:mm:ss (or m:ss). Rows are the original length at 1x.

The rule behind every number: new length = original length ÷ speed. Doubling the speed always halves the time, and each step above 2x saves less extra time than the one before.
