GTM filmmaker

Longform turns a single prompt into a real-looking, emotional short video. Ask for "a company video for Coca-Cola" and an AI agent researches the brand, asks a few follow-up questions, writes the story, and renders it with FLUX 3. Editing works like a conversation. Grab any moment on the timeline and say what to change ("make it snow", "make it 3 seconds longer"), and only that part is regenerated. Every video, prompt and finding is saved to RawTree. The agent, powered by Liquid, gets better with each video you make. Built with: Liquid LFM (OpenRouter) · RawTree · BFL FLUX 3 · Next.js
