Pick a build, cast your star, and BatchGen storyboards every frame — consistent characters, before-and-after arcs, and one-click animation when a scene is ready.
Demo mode — frames render as placeholders and AI prompt rewriting is off. Sign in to BatchGen to build for real with your own Gemini key.
Storyboard setup
Pick a topic and length. Your Gemini key writes a scene-by-scene storyboard — one keyframe and one 8-second clip per scene.
Make it yours
Type a new shape (anything — dolphin, SpongeBob, Pokéball), optionally restyle the house and tiles, then press Update prompts. Your Gemini key rewrites every frame's prompt to match.
The build’s beats never change — these swap what they’re made of. Every field has a default from the original build; leave one empty to keep it. Suggest themes them all to your setting (leave the setting empty and it invents one), then edit anything by hand and press Update prompts.
One-shot build & cost planner
One button builds everything: all frames generate in order (each auto-approves and chains as a reference), then every clip renders. You can cancel anytime, and the cost below is estimated before you start.
Veo renders on your Gemini key; Kling, Omni Flash, and Seedance render on your Atlas Cloud key. Your images always use Nano Banana on your Gemini key.
Midpoint check
Review your images below — click any to zoom, or use its dice to redo it. When you’re happy, render the clips.
