How to create a speed ramp

Upload a video, select a speed preset, adjust the curve by dragging keyframes, set the trim points, preview the result and export. Output format depends on which formats your browser supports.

Using Video Speed Ramp Editor

Set source-time speed keys for variable-speed playback, review timing and optional audio, then record an output supported by the browser.

Workflow

Open a browser-decodable clip and add speed keys or choose a preset.

Preview the ramp and trim range; check audio behavior through slow and fast sections.

Record the result and inspect the video, curve CSV or project JSON in the intended software.

Example

Slow a brief action with a gradual ramp, add a return-to-normal key, preview the trimmed range, then compare the recorded clip with its curve CSV.

Limits and data handling

Recording is real-time and browser-dependent; frame pacing and codec support vary. Review audio synchronization across speed changes. Curve CSV and project JSON describe edit data, not rendered video. Keep the source footage separately.
