FLUX 3: flexible 5–20s video with draft and audio
Black Forest Labs FLUX 3 on SupaImagine — text or multi-image storyboard, draft-first rates, optional sound.
FLUX 3 runs text-to-video and image-to-video only (no source-video continuation on this SKU). Duration is an integer from 5 to 20 seconds (default 5). Resolution is draft-720p, 720p, or 1080p (default draft-720p). Text-to-video exposes common aspect ratios including auto; image-to-video follows the supplied stills and accepts up to ten images as an ordered storyboard. Pricing is about 5 credits per second on draft-720p, 15 on 720p, and 25 on 1080p, with a 25-credit minimum per run — so a five-second draft defaults to 25 credits. Signup credits (10) cannot fund that floor; buy credits or a plan before you generate. Commercial use sits on paid plans under the Terms.

Four controls · one FLUX 3 lane
Four controls that define a FLUX 3 take
Prompt or storyboard, draft then full quality, length, and optional sound — pay for the seconds and tier you queue.
Write a continuous scene when nothing exists yet
Subject, action, camera, and light go in one FLUX 3 prompt for a single continuous beat — hooks, product glides, or establishing inserts. Text-to-video is not a multi-scene cut list; keep the instruction focused so motion stays coherent across the seconds you pick. Negative notes (for example no on-screen text) live in the same prompt. This is the FLUX 3 text to video path when you start from blank paper.
Drive the clip with one still or a multi-image storyboard
Upload a product shot, key art, or character still when composition is already approved, then describe the motion you want. FLUX 3 image to video accepts up to ten images in order: one image opens the clip, two act as start and end, and three to ten become an evenly spaced storyboard. There is no source-video restyle path on this SKU — boards in, motion out.
Preview on draft-720p, then promote winners
Default resolution is draft-720p so you can judge motion and framing before full rates. Draft bills at about five credits per second (25-credit floor). When a FLUX 3 draft looks right, raise the same idea to 720p or 1080p and re-run — that draft-then-full habit is the cost control, not a separate model. Full 720p is about fifteen credits per second; 1080p about twenty-five.
Pick 5–20 seconds and optional synced audio
Duration is an integer from five to twenty seconds, billed per second at the resolution you choose. Audio defaults on for FLUX 3 so ambient sound, speech cues, or effects can ride with the picture; turn it off for a silent export when you will score the track later. Set seconds and audio before the queue so the estimate matches the file you want — signup balance (10 credits) cannot cover the 25-credit floor on a default draft run.
From brief to seconds
Write or upload, pick length and quality, then generate FLUX 3
Four decisions before the queue: material, instruction, tier, and length.
1
Choose text or ordered stills
Blank prompt for a new scene, or one to ten images when boards already own the look. Order matters for storyboard starts and ends.
2
Write one clear motion brief
Name subject, action, camera, and light. Keep one continuous beat so FLUX 3 can hold coherence across the seconds you pick.
3
Lock draft or full quality, 5–20s, and audio
Default is five seconds on draft-720p with audio on. Stretch length only when the beat earns it; promote keepers to 720p or 1080p after a draft win.
4
Generate, review, then promote or refine
Queue the FLUX 3 run, check the file in your library, then re-run with tighter wording, longer duration, or a higher resolution tier.
Jobs that fit this flexible short lane
Jobs that fit a flexible FLUX 3 short
Situations where 5–20s with draft previews and multi-image control beats a fixed eight-second-only model.
Ad hook variants on draft rates
Spin several five-second FLUX 3 draft hooks, pick the winner, then re-render that single idea at 720p or 1080p for paid social.
Packshot motion from an approved still
Animate a product board with image-to-video when composition is locked and you only need a clean motion pass with optional sound.
Multi-image storyboard beats
Upload three to ten boards so FLUX 3 bridges an ordered storyboard instead of cutting between unrelated clips.
Previz before full-quality spend
Block scenes as draft-720p previews so stakeholders agree on motion before anyone burns 1080p rates.
Vertical social with flexible length
Set 9:16 on text-to-video, start at five seconds, then stretch only keepers toward ten or twenty seconds.
Same brief, other model families later
Use FLUX 3 for draft-first multimodal shorts, then compare winners against Veo or Seedance when you need a fixed eight-second family or native 4K.
Explore other video models
One plan, every video model — pick a better fit for length, resolution, or input style.
Veo 3.1
Text or first/last frames — not reference stacks, not flexible duration. Sound rides with the picture by default; lock 720p, 1080p, or 4K before credits move.
Gemini Omni Flash
Text, a still, or a source video — 3–10 seconds, 16:9 or 9:16, 30 credits per second.
Seedance 2
The only Seedance tier with 1080p and 4K — always-on synced audio, 4–15s from text, frames, or refs.
HappyHorse 1.1
Joint audio and mouth motion in 7 languages — text, a first frame, or up to 9 reference images.
FLUX 3 questions before you spend
How long can a FLUX 3 clip be, and what does each second cost?
FLUX 3 exposes 5–20 second lengths. Draft-720p is about 5 credits per second, 720p about 15, and 1080p about 25, each with a 25-credit minimum per run. A five-second draft default costs 25 credits; a five-second 720p run is 75; a five-second 1080p run is 125. Set duration and resolution before you run so the estimate matches the file you want.
What inputs does FLUX 3 accept on SupaImagine?
A written prompt for text-to-video, or one to ten images for image-to-video (ordered storyboard). There is no source-video continuation (v2v) on this FLUX 3 SKU.
Does FLUX 3 support draft-720p and full quality on the same model?
Yes. Resolution is draft-720p, 720p, or 1080p on one FLUX 3 generator. Start on draft for cheap previews, then re-run the same idea at 720p or 1080p when the motion is locked. There is no 4K option on this video SKU.
How does the multi-image storyboard work for FLUX 3 image to video?
Upload up to ten stills in order. One image opens the clip; two act as start and end; three or more become evenly spaced storyboard boards (the first starts, the last ends). Duration must fit the beat you want between those boards.
Can I try FLUX 3 free with signup credits?
No. Signup credits are 10, and the default FLUX 3 draft run floors at 25 credits. Buy credits or a plan before the first run.
Does every FLUX 3 export include synchronized audio?
Audio defaults on for FLUX 3 and generates synchronized sound with the picture. You can turn audio off in the generator when you need a silent file to score later.
Which aspect ratios work for FLUX 3 text to video?
Text-to-video offers auto plus common ratios from 21:9 through 9:16 (including 2:1, 16:9, 4:3, 1:1, and 3:4). Image-to-video follows the supplied stills, so crop boards first when the feed needs a different frame.
Are paid-plan FLUX 3 clips cleared for commercial work?
Paid-plan runs follow SupaImagine Terms for commercial use. You still need rights to any third-party faces, brands, or stills you upload as storyboard images.
