Resize Video Duration — Set an Exact Target Length

Specify how long you want a video to be and the tool calculates the playback speed automatically. Make a 30-second clip fit into 15 seconds, or stretch a 5-second clip to 10.

Handy when a platform has strict time limits, when you need a clip to match a specific audio length, or when you want quick presets like 2x or 4x compression. Speed and duration inputs stay in sync.

Frequently Asked Questions

How is this different from speed changer?

You set the target duration and the tool calculates the right speed. [Speed Changer](/video/speed-changer) works the opposite way — you set the multiplier.

Can I make a 2-minute video fit into 60 seconds?

Yes. Set 60 seconds as target and the video plays at 2x speed. Audio pitch changes accordingly.

What's the shortest target duration?

There's no hard minimum, but extremely short durations make the video unwatchable. Keep it reasonable.
