Create 2K cinematic clips with precise lip-sync and camera control
Black Forest Labs' FLUX 3 Draft turns a written scene into a fast 720p text-to-video preview with optional native audio, built for cheap prompt trials before a full-quality pass. Trading expensive final-quality reruns for quick draft checks while keeping a reusable draft cache for later enhancement, FLUX 3 Draft helps marketers, previz artists, and social teams iterate without burning budget. For developers, FLUX 3 Draft on RunComfy can be used both in the browser and via an HTTP API, so you don't need to host or scale the model yourself.
Ideal for: Prompt Draft Previews | Low-Cost Storyboards | High-Volume Social Tests
This page covers the text-to-video draft endpoint in the FLUX 3 family. You describe a scene in plain language; the model returns a quick 720p clip so you can validate ideas without paying full FLUX 3 Video rates.
The endpoint is built for the early loop of creative work: prompt tuning, shot planning, and batch draft runs. When a take looks right, reuse the returned draft cache with draft-enhance for a fuller finish.

FLUX 3 Draft is a Black Forest Labs text-to-video endpoint that renders fast 720p preview clips from a written prompt. It fits prompt trials, storyboards, and high-volume draft runs where speed and cost matter more than final sharpness.
Both share the text-to-video path; FLUX 3 Draft outputs a cheaper 720p preview and returns a draft cache you can enhance later, while full FLUX 3 Video is better for polished 720p or 1080p deliverables.
FLUX 3 Draft accepts duration as auto or 5–20 seconds, with aspect ratios auto, 21:9, 2:1, 16:9, 4:3, 1:1, 3:4, and 9:16. Check the RunComfy parameter panel for the live controls on this page.
No. FLUX 3 Draft is text-only: scene, motion, lighting, and camera direction all come from the prompt. For still-driven drafts, use FLUX 3 Draft Image to Video or other FLUX 3 draft modes.
Along with the preview clip, FLUX 3 Draft returns a reusable draft cache that can be passed to draft-enhance for a fuller-quality render without regenerating the whole idea from scratch.
Yes. Prototype in the RunComfy model UI, then call the same FLUX 3 Draft template through the RunComfy API with matching parameters. Generations consume usd / credits on both paths.
FLUX 3 Draft is billed at $0.07 per second of generated draft video at 720p. A 5-second clip costs about $0.35; longer durations scale with the output length.
Stay on FLUX 3 Draft for drafts, batch variants, and early creative reviews. Move to full FLUX 3 Video or draft-enhance when you need sharper finals for ads, client delivery, or higher-resolution platforms.
