Video Variations: One Idea, Infinite Angles to Test

A/B variations take one idea and produce several versions of the same video, each with a different hook, pacing, editing style or call to action, so you can post them and see which angle your audience responds to. The idea stays fixed, which is what makes the comparison meaningful rather than just producing several different videos.

They are coming soon. Start your ShortFast trial from this page to get early access when they ship.

Give an automation one theme and ShortFast keeps the series going. For every slot it reads the series theme and the first video's tone, format and length, checks the titles of your most recent episodes, and writes the next episode: a fresh topic on the same theme, a new script and hook, a new title and description, and new footage to match.

The next two episodes stay queued, where you can open them to edit the subtitles, footage and caption, re-time them, pin them or delete them, and then each one is posted or emailed to you. A format that works keeps working, and the audience gets something new every time.

Developers can ask for the next episode of a specific video. The REST API creates a variation of any generated faceless video with POST /api/v1/videos/:id/clips, and the MCP server lets Claude, Cursor and other agents do the same in plain language. Each variation uses credits like any other video.

When you want to test a specific opening today, write or paste your own script before generating. ShortFast keeps your words, so the hook you wrote is the hook that goes out.
