FLUX 3 — AI Video Generation

Text, image or keyframes. 5 to 20 seconds. 720p or 1080p. Audio.

FLUX.3 is the video model from the team behind the FLUX image models. Start from a prompt, a still or a first and last frame, and get a 5 to 20 second clip with native audio, then extend it.

Decide where it starts and ends

First frame, last frame, motion in between

Give FLUX.3 two images and it builds the shot that connects them. You decide exactly how a scene opens and closes, so a product reveal lands on your packshot and a transition ends on the frame the next clip starts with.

Twenty seconds in one take

Clips run anywhere from 5 to 20 seconds, so a full product moment, a slow reveal or a short scene with dialogue fits in one generation. Fewer cuts means fewer places for faces, light and props to change between shots.

Extend past the last frame

FLUX.3 Extend picks up where a clip ends and adds another 5 to 20 seconds. Use it to let a scene breathe, add an ending, or join two generations into one continuous shot.

FLUX.3 questions

What is FLUX 3?

FLUX 3 is Black Forest Labs' video model on PicX Studio. It supports text-to-video, image-to-video, and first-and-last-frame video creation with native audio.

What can I use as input?

Start with text alone, add an image to animate it, or use a first and last frame to guide the beginning and end of a shot.

How long can a FLUX 3 video be?

FLUX 3 supports video durations from 5 to 20 seconds.

Which resolutions are available?

Choose 720p for faster iterations or 1080p when you need a higher-resolution final output. 720p costs 65 credits a second and 1080p costs 98.

Does FLUX 3 generate audio?

Yes. FLUX 3 supports native audio generation as part of the video workflow. You can turn it off, and the price stays the same either way.

Can I continue a completed video?

Yes. PicX Studio also offers FLUX 3 Extend for continuing an existing clip beyond its final frame, by 5 to 20 seconds at 157 credits a second (720p) or 179 (1080p).

Is FLUX.3 an image model or a video model?

On PicX Studio, FLUX.3 is a video model. Black Forest Labs is best known for its FLUX image models; for stills here, use an image model such as Nano Banana Pro or Seedream, then animate the result with FLUX.3.

How much does a FLUX.3 video cost?

65 credits per second at 720p and 98 at 1080p. A 5 second 720p clip is 325 credits; a 20 second 1080p clip is 1,960 credits.

Can I try FLUX.3 for free?

Your first image is free after you sign up, no card needed. Video models, including FLUX.3, need a plan or a one-time credit pack. Credits never expire.

How do I create a FLUX.3 video?

Select FLUX.3 and write a concise prompt that names the subject, action, setting and camera motion. Attach one image to animate it, or a first and last frame pair to control the start and end. Choose a duration from 5 to 20 seconds and 720p or 1080p, decide whether you want sound, then generate. Review the clip, download it, or send it to FLUX.3 Extend to keep going.

How does first and last frame to video work in FLUX.3?

Keyframe mode takes two images: the frame the clip opens on and the frame it ends on. FLUX.3 works out the motion between them, guided by your prompt. It suits product reveals that must end on a packshot, before-and-after shots, and transitions between scenes. Use two images with the same aspect ratio and similar lighting, and describe the movement that links them, such as "the camera orbits left as the box opens".

How do I make a 20 second clip with FLUX.3?

Longer clips need a prompt with a shape. Describe a beginning, a middle and an end, for example an establishing view, a move toward the subject and a final reveal, instead of one static action. Name one camera path for the whole clip. If the second half drifts, shorten the clip and use FLUX.3 Extend for the rest, so you can steer each part separately.

When should I use FLUX.3 Extend instead of a new generation?

FLUX.3 Extend takes a finished video and continues it beyond its final frame by 5 to 20 seconds, at 720p or 1080p. Describe what happens next in the prompt. Extend costs more per second than a fresh generation, 157 credits a second at 720p and 179 at 1080p, so use it when continuity matters: the same shot, the same light, no cut.

Should I turn audio on or off in FLUX.3?

FLUX.3 can generate dialogue, effects and ambience with the picture. On PicX Studio the price is the same with or without sound, so leave it on to judge pacing and mood, and turn it off only when you will lay your own music or voice-over on top. Describe the sound you want in the prompt: footsteps, wind, a crowd, a short line of dialogue.

Direct the shot. Generate the motion.

Create 5–20 second FLUX 3 videos from text, images, or keyframes, with 720p, 1080p, and native audio on the same PicX Studio workflow.
