A product launch needs a video. But shooting, editing, and producing one takes time, budget, and a team most people do not have sitting around. This skips all of that. You brief your assistant on the product and the launch angle, and it writes a script, generates the visuals using Gemini, and assembles a complete video you can share — without touching a timeline editor or waiting on a production cycle.
The prompt
Send this in Slack. The more context you give, the sharper the video.
Make a short launch video for [product name].
What it is: [one sentence describing the product]
Who it is for: [audience]
Launch moment: [what is happening — new release, announcement, waitlist opening, etc.]
Tone: [e.g. punchy and exciting / calm and confident / playful]
Length: 60 seconds
Write a 6-scene script. For each scene: a visual description Gemini can generate, and the text overlay or voiceover line.
Then generate the visuals with Gemini, assemble the scenes in sequence, and add the text overlays.
Output a single video file ready to post.Adjusting the output
Once you see the first cut, you direct in plain language.
Scene 3 feels too abstract. Redo the visual — something more grounded, a person actually using the product in a real workspace.The pacing is too slow in the first half. Trim scenes 1 and 2 by a third and punch up the text overlays — shorter, more direct.How it works
Your assistant takes the brief and writes a scene-by-scene script with two outputs per scene: a visual prompt for Gemini and a line of copy for the overlay or voiceover. It then sends each visual prompt to Gemini to generate the frame, collects the outputs, and uses ffmpeg to assemble the scenes into a single timed video with text overlays baked in.
When you give feedback on a specific scene, it regenerates only that scene and re-assembles. You are not re-running the whole pipeline each time — just the part that needs changing. The script lives in memory so every iteration has the full context of what was already decided.
The outcome
A ready-to-post launch video in under 20 minutes, produced entirely from a Slack message. No editing software, no video team, no waiting on a creative agency. The whole thing — script, visuals, assembly, text overlays — happens autonomously while you are doing something else. You come back to a file you can drop directly into Twitter, LinkedIn, or a product announcement post.
