Slow it down or speed it up
Changing playback speed is a simple edit with big impact. Slow motion draws attention to detail — a golf swing, a reaction, a product in action — while speeding up turns long processes into snappy, watchable clips.
Slide below 1x for slow motion or above it for fast-forward, and the audio is re-timed to stay aligned with the picture. Since rendering happens locally, you can dial in exactly the right pace across as many exports as you need.
