Flux.3 Video is Black Forest Labs' video model: 5–20 second clips with native sound and dialogue, from text or a still. It is the video release of FLUX 3, the lab's first video model, announced July 23, 2026 and generally available from August 4, 2026. On Elyum it does text-to-video and image-to-video.

Use it when you need a talking clip with the line already in the file, a still that should move, or a short that switches camera inside one take. Web studio, MCP, or REST — one credit balance.

Why Flux.3 Video is good

Native audio in the same take

Dialogue, effects, and ambience generate with the frames. Quote the spoken line in the prompt if you want speech. You do not stitch a silent clip and a separate soundtrack.

5–20 seconds at 720p or 1080p

Clips run 5 to 20 seconds in one generation at 720p or 1080p. Seven aspect ratios. Rate is per kept second: 23 credits/s at 720p, 34 at 1080p.

Text to video and image to video

Describe the scene in plain language or a detailed prompt, or pin a still as the opening frame. On Elyum those are the two routes. Native audio is on both.

Multilingual speech, lip-synced

BFL lists lip-synced speech in English (several dialects), Chinese, Spanish, French, German, Japanese, Portuguese, Russian, Italian, Indonesian, Turkish, Hindi, Punjabi, and more. Put the line in the prompt.

Multiple shots in one take

The model can change scene and camera angle inside a single clip and keep the sequence coherent. BFL also notes on-screen type as part of the picture, not a later overlay.

Pay only for keeps

Preview is free. A 5-second 720p keep is 115 credits ($1.15); 15 seconds is 345 credits ($3.45). Kill refunds the rest.

What people make with it

Frequently asked questions

Is Flux.3 Video free to try?
Yes. Every render comes back as a free preview. The Free plan includes up to 100 credits (our algorithm may grant them). You only pay when you keep a take; kill refunds the rest in full.
How much does Flux.3 Video cost on Elyum?
You pay per kept second, not per prompt. 720p is 23 credits per second — 115 credits ($1.15) for 5 seconds, 345 credits ($3.45) for 15. 1080p is 34 credits per second — 170 credits ($1.70) / 510 credits ($5.10). Killed takes refund in full.
Does Flux.3 Video generate audio with the video?
Yes. Sound and dialogue are native to the clip: speech, effects, and ambience in the same pass as the picture. Prompt the spoken line if you want speech. You preview the audio with the take, then keep or kill as usual.
What can Flux.3 Video do besides text to video?
On Elyum it does text to video and image to video. Clips run 5–20 seconds at 720p or 1080p, with seven aspect ratios. Native audio is on both.
Can I use Flux.3 Video videos commercially?

Flux.3 Video vs other AI video models on Elyum?
Flux.3 Video is the Black Forest Labs pick: native audio, 5–20 second clips from text or a still, including multilingual speech. Other studio models trade that for longer clips, more references, or a different motion grammar. Same credit balance either way.
