FLUX 3 Video

FLUX 3 Video is Black Forest Labs' first public video generation model, part of the FLUX 3 family announced on 23 July 2026. It makes clips of up to 20 seconds with synchronized sound — dialogue, sound effects and ambience — from text, images, keyframes or an existing clip. On Kenerate you can run text to video and image to video.

Black Forest Labs announced FLUX 3 on 23 July 2026, with FLUX 3 Video and FLUX 3 Action in early access. General API access opened on 4 August 2026. It is available on Kenerate now, with no waitlist.

It's billed per second: 42.5 credits a second at 720p and 72.5 at 1080p, rounded up per clip. A 5-second clip costs 213 credits at 720p or 363 at 1080p; a 20-second clip costs 850 or 1,450. Sound on or off costs the same. Credits come in one-time packs from $15 for 1,300.

Not on Kenerate's free plan — video needs any one-time credit pack, with no subscription. The cheapest FLUX 3 Video clip is 5 seconds at 720p for 213 credits.

Not yet. Black Forest Labs has said faster and open-weight versions of FLUX 3 are planned for later in 2026, and the family includes a FLUX 3 Dev variant, but as of 20 October 2026 the video model runs only through APIs and hosted apps.

Not locally — there are no downloadable weights to load yet. API-based ComfyUI nodes may call it, but the simplest way to try it today is in the browser on Kenerate or another hosted platform.

5 to 20 seconds per clip, in whole seconds. That's longer than most models' 10–15 second limit; for up to 30 seconds per clip, Seedance 2.5 and Wan 3 go further.

On Kenerate you can pick 720p or 1080p, in 9:16, 21:9, 2:1, 16:9, 4:3, 1:1 or 3:4. Reports at launch described HD output with Full HD by upscaling, so test at 720p and move to 1080p for the keeper.

Yes. It generates audio together with the picture — dialogue in several languages, effects and ambient sound synced to on-screen events. On Kenerate sound is a toggle and the price is the same with it on or off.

FLUX 3 Video makes longer clips (up to 20 s) from text or one start image and is cheaper per second at 720p (42.5 vs 72 credits). Seedance 2.0 takes up to 9 images, 3 clips and 3 audio files as references and goes up to 4K, so it's the better pick when you need tight control over a character or a camera move.
