Change speed

Speed up a clip

1. Click a clip on the timeline to select it. To change part of a clip, split it first.
2. Press S, or click the speed button in the timeline's toolbar.
3. Pick a speed: 0.5×, 0.75×, 1×, 1.2× up to 2×, then 3×, 4×, 8×, 16× or 24×. Choose Custom to type any speed from 0.1× to 24×.

The clip on the timeline gets shorter or longer to match. Its speed also shows in the clip's settings on the right, under Speed.

Sound is sped up without the chipmunk effect: voices keep their pitch. On a clip faster than 2×, its recorded sound plays at 20%, so sped-up talk doesn't chatter over the video. The clip's settings say so under Speed.

Smooth changes of speed

Where one clip plays straight on into the next at another speed, Cinemac eases from one speed to the other over about half a second, so the video doesn't lurch from 1× to 4×. Each clip keeps its length. The speed badge on a clip shows a small ramp where its speed eases in or out.

There's no easing at a cut, a slide or a join with a move of its own. Those change at once.

Fast clips look smooth

On a clip at 2× or faster, the exported video blends the frames it skips, so scrolling and typing glide instead of stepping. Stills, frames you copy and GIFs stay sharp. Turning motion blur off turns this off too.

Several clips at once

Select several clips with ⇧-click, then press S. To give every clip the same speed, right-click a clip and choose Apply speed to all clips.

Typing

Stretches where you type are found for you and offered as a speed-up. See Speed up typing.
