<strong>Follow The Build</strong>

Turn your AI coding assistant into a full video production studio. Describe what you want in plain language — your agent handles research, scripting, asset generation, editing, and final composition.

Important distinction: OpenMontage can make image-based videos, but it can also make a real video video for free/open-source workflows: the agent builds a corpus from free stock footage and open archives, retrieves actual motion clips, edits them into a timeline, and renders a finished piece. That is not the usual "animate a handful of stills and call it video" trick.

"OBJECTS IN OVERDRIVE" — a 54-second, music-driven 3D showcase featuring ten objects with distinct choreography: gravity-shifting furniture, frozen car drifts, cloth impacts, refractive lenses, moving gears, an acrobatic robot, and more. Custom Blender animation and physics, kinetic typography, and a phonk soundtrack. Rendered with Blender Eevee/Cycles and assembled with FFmpeg. No narration.
