What This App Does
FLUX 3 can make a video in two steps. First a draft: a fast, low-cost 720p preview of your prompt, with its sound. If you like it, the draft is rendered in full 1080p quality: the final keeps its scene, composition and timing, while the details are generated anew, so it is a refined take rather than an upscale of the same pixels. You only pay the full price for the takes you keep.
This template wires those two steps around a switch. With the Final render switch off, a run makes the draft only. Turn it on and the draft is sent on to the final render. In the editor, keep the switch off while you iterate on the prompt, then turn it on and run only the final node to render the draft you are looking at. In the app form and the API, a run with an empty draft_cache makes a draft and returns its draft_cache. To render that draft, run again with the draft_cache pasted in: the run makes only the final video.
Key capabilities
Draft first — a quick 720p preview at a fraction of the full price
Final render — the full-quality 1080p version of that same draft
Native audio — ambience, effects and speech generated in sync with the picture
Clips from 5 to 20 seconds
Framing — auto picks a ratio from the prompt, or choose 21:9, 2:1, 16:9, 4:3, 1:1, 3:4 or 9:16
The draft node also works from an image, a first and last frame, or a clip to extend: change its mode
Core inputs
prompt (text, needed for a draft) — the scene, the action, the camera movement and the sound you want
draft_cache (optional) — leave empty to make a draft, or paste the draft_cache of a previous run to render it in 1080p
duration — 5 to 20 seconds (default 5); the final video has the length of its draft
aspect_ratio — auto (default), 21:9, 2:1, 16:9, 4:3, 1:1, 3:4 or 9:16
generate_audio — on by default
A draft run returns draft_video and draft_cache; a final run returns final_video.

Prompt
A barista pours steamed milk into a cappuccino and draws a leaf of latte art, in a sunlit café. Close-up with shallow depth of field and a slow push-in. We hear the milk steamer hiss, cups clink and soft café chatter.

Frequently Asked Questions
Do I need a subscription to use FLUX 3 Draft to Final?
No. Buy a credit pack once, generate, and come back whenever you want. Purchased credits stay valid 12 months, and every new purchase extends them.
What does this template do?
It makes a cheap 720p draft of your video with FLUX 3, then renders the draft you keep in full 1080p quality.
Is the final video the same as the draft?
It follows the draft closely: same scene, overall composition and timing. The details are generated anew at full quality, so framing and small elements can change; it is not a pixel-for-pixel upscale.
Why make a draft first?
A draft costs a fraction of a full render and comes back faster, so you can try several prompts and only pay the full price for the one you keep.
How do I use the switch in the editor?
Leave Final render off while you iterate. When a draft looks right, turn the switch on and run only the FLUX 3 Final node: it renders the draft already on screen.
And in the app form or the API?
Run once with draft_cache empty: you get a draft and its draft_cache. When a draft looks right, run again with that draft_cache pasted in: you get its 1080p final, and no new draft is made or charged.
Does it generate sound?
Yes, both the draft and the final video have a synchronized audio track by default. Turn generate_audio off for a silent clip.
How long can the videos be?
5 to 20 seconds, 5 by default. The final video has the same length as its draft.
What resolution do I get?
Drafts are 720p. The final render is 1080p.
What drives the price?
The duration. A draft costs much less per second than the final render, which is only charged when you render a draft.
Can I start from an image instead of text?
Yes. Change the mode of the FLUX 3 Draft node to Image to Video, First and Last Frame or Extend Video; the draft and final steps work the same way.
How do I know what a generation will cost?
The app shows the exact price on the Generate button and updates it as you change the settings, before anything is billed.
Is there a free trial available?
Yes, AI-FLOW offers a free trial to get you started. After that, you can purchase credits as needed—no subscription or long-term commitment required.
