Video Scenario Maker: Plan video scenes by the second and copy AI video prompts

Video Scenario Maker is a free, browser-based storyboard editor for AI video. Set each scene's duration, reference image, dialogue, shot size, camera move and lighting on a dark, editor-style timeline, then preview images, subtitles and music in sync. It turns your plan into copy-ready English prompts for Sora, Veo and other generators, per scene or as one timecoded prompt, plus per-speaker voice notes, a music prompt and an SRT file. No sign-up; your data stays in your browser.

Hi Product Hunt! AI video generators usually give you a few seconds per generation, so a short video ends up being a stack of separate shots. I kept losing track of timing, camera directions and dialogue across those prompts, so I built Video Scenario Maker. How it works: 1. Lay out scenes on a timeline and set each one's length in 0.5-second steps. 2. Add a reference image, dialogue, shot size, camera move and lighting to each scene, and pick a voice for each speaker. 3. Preview images, subtitles and music together, then copy the prompts (per scene or as one timecoded prompt), a music prompt and SRT subtitles. It's free, there's no sign-up, and everything stays in your browser. I'd love to hear which generator you'd use it with and what you'd want added next.
