How to edit a clip with AI

With a clip selected, scroll the editor’s right column to the “AI refine” section. It has a text box and a “Refine” button.

Plain English. Sliver translates intent into a structured JSON patch under the hood, so phrasing is forgiving.

“Extend by 5 seconds.” “Trim 2 seconds off the end.” “Center it instead of tracking the speaker.” “Add a title at the top.” “Add a caption at the bottom that says ‘episode 12’.” “Watermark with @jasontmiani.” “Punchier hook — rewrite the title.” “Clear the title.” “Hide captions.”

Sliver streams the request to Claude, which calls the apply_edit_patch tool with the minimal set of changes. The AI’s one-sentence reasoning is logged above so you know what it interpreted.

As soon as the patch applies, the editor kicks off a 600 ms-debounced re-render. The preview swaps to the new cut within ~5–8 seconds on Preview quality, or ~25–30 s on the higher-quality default.

The refine panel keeps the last 10 prompts in history. Tap “Revert” next to any entry to roll back to that state.
