Change the duration of a clip

Pēdējo reizi atjaunināts 2026. gada 22. sept.

Adjust the playback speed to make your clip shorter or longer in Premiere mobile.

You can change the duration of a clip by adjusting its speed. Slowing down a clip extends its duration for dramatic effect, while speeding it up shortens the clip to fit more action in less time.

Open your project and tap the clip you want to adjust in the timeline.

In the bottom toolbar, scroll through the options from right to left and tap Retime > Speed.

Speed and Freeze options shown after tapping Retime, with Speed highlighted. — Choose Speed to adjust how fast or slow the clip plays, which changes its overall duration.

Drag the speed slider to set a value between 0.1x (slowest) and 10x (fastest).

Speed panel with slider set to 1.66x, showing the clip duration reduced from 8.0 to 4.8 seconds. — Drag the Speed slider to set a new rate; the clip's duration updates automatically to match.

As you adjust, the new clip duration appears below the speed bar.

Open your project and tap the clip you want to adjust in the timeline.

In the bottom toolbar, scroll through the options from right to left and tap Retime > Speed.

A clip on the timeline with speed keyframes applied, with the Speed button highlighted in the toolbar.

Drag the speed slider to set a value between 0.1x (slowest) and 100x (fastest).

The Speed panel, showing a slider from 0.1x to 100x set at 1x, with Linear and Curves options below. — Drag the slider to set a custom speed, or choose Curves to vary it over time.
