FLUX 3 Video overview
A video model designed to understand the whole audiovisual scene
Black Forest Labs positions FLUX 3 as a multimodal model rather than a silent image animator. It can combine motion, camera direction, scene changes, dialogue, ambient sound, and effects in one generation while moving between natural, raw, playful, nostalgic, strange, and cinematic visual languages.
Longer narrative room
Up to 20 seconds gives a product beat, dialogue exchange, reveal, or short educational sequence time to develop instead of ending at the setup.
Multiple shots in one take
Direct scene changes and camera angles inside one generation while asking the model to preserve the subject, style, and audiovisual logic.
Sound belongs to the action
Generate speech, accents, room tone, Foley, weather, mechanical sounds, and music cues alongside visible events rather than adding generic audio later.
Generation modes in Neurohelper AI
Choose between free invention and a controlled starting frame
The current Neurohelper AI integration includes two FLUX 3 Video routes. Start from text when the model can invent the entire scene, or attach one source image when the person, product, composition, environment, or visual style is already approved.
Invent the complete scene
Describe subject, environment, action, camera, sequence, visual language, spoken lines, and sound. Best when no exact product or character identity must be preserved.
Animate an approved direction
Use one source image to establish the opening composition, person, product, setting, lighting, or style. Let the video prompt focus on motion, performance, camera behavior, and audio.
Creative and marketing video cases
Six FLUX 3 Video demonstrations made in Neurohelper AI
Watch practical Text to Video and Image to Video outputs with native audio, then open each prompt to see the direction behind the finished clip. The examples cover hospitality, multilingual UGC, event visualization, continuous action, stylized storytelling, and educational content.
From empty room to the first guest
Use a compact multi-shot timeline to create a complete branded mood film rather than one disconnected beauty shot.
View video prompt
Video: Create a 10-second 16:9 naturalistic film for the fictional neighborhood coffee shop NORTH HOLLOW. Early rainy morning, warm practical light, restrained documentary photography. Use three concise connected shots: 0–3 seconds, exterior through rain-speckled glass as the owner switches on the lights; 3–6 seconds, close view of coffee grinding and steam as one plain dark-green cup is placed on the counter; 6–10 seconds, a soaked cyclist enters, receives the cup, and relaxes beside the window. Preserve the same owner, cyclist, interior, cup color, weather, and visual tone. Native audio: soft rain, door bell, grinder, steam wand, ceramic contact, and quiet room tone. No narrator, real logo, readable packaging, or exaggerated slow motion.
A vertical ad that keeps the person and product stable
Test multilingual speech and lip sync without asking the model to perform complicated product handling at the same time.
View source-image and video prompts
Source image: A fictional creator stands at a bright kitchen counter holding one closed matte-blue LUMEN DAY planner beside her shoulder. The cover design is simple, invented, and clearly visible. Her hands and the planner are already in their final positions.
English version: Create a 14-second vertical clip from the supplied image. Preserve the exact person, face, clothing, hand position, planner, kitchen, lighting, and framing. She looks into camera, makes one natural blink, and says warmly: “This is the five-minute reset that finally made my mornings feel manageable.” Leave a brief natural pause before and after the line. Subtle smartphone micro-movement, quiet kitchen ambience, no object movement, cuts, captions, or music.
Spanish version: Use the same 14-second locked setup and restrained performance. She says naturally: “Este reinicio de cinco minutos por fin hizo que mis mañanas fueran más llevaderas.” Preserve identity, voice character, product, composition, and pacing.
Animate a finished launch-night key visual
Start from a source image that already contains the architecture and fictional installation, then direct only restrained movement and atmosphere.
View source-image and video prompt
Source image: A finished 16:9 visualization of a fictional launch night in a concrete gallery: one suspended translucent ring, four low black plinths, restrained cyan and violet light, and a small invited audience. Centered camera, polished floor, no readable text or real logo.
Video: Create a 10-second 16:9 clip from the supplied image. Preserve the room, installation, camera position, lighting design, plinths, guests, and composition. Over the full shot the suspended ring turns very slowly, light reflections travel naturally across the floor, two guests shift their attention toward the installation, and one person crosses the distant background with subtle motion blur. Use one slow controlled push-in. Native audio: room reverb, quiet conversation, soft footsteps, and a low electrical hum. No new objects, architecture changes, dramatic light switch, text, logo, or close hand interaction.
Coordinate environment, camera, and changing acoustics
Use one focused Text to Video generation for a complete movement arc with clear timing and stable visual anchors.
View video prompt
Video: Create an 8-second 16:9 naturalistic continuous shot with no cuts. At dusk, a fictional cyclist rides at a steady pace along a wet coastal road while the camera tracks smoothly from the left. During seconds 2–5 the cyclist enters a short concrete tunnel; reflections tighten around the wheels and the audio gains natural tunnel reverb. During seconds 5–8 the camera shifts toward a rear three-quarter angle as the cyclist exits toward a pale strip of sunset. Preserve the same rider, bicycle, clothing, road, weather, speed, camera height, and color grade. Native audio: wind, tire spray, drivetrain, tunnel reverb, and distant surf. No crash, vehicle, dialogue, logo, jump cut, or sudden acceleration.
A capybara prepares midnight noodles
Show that FLUX 3 is not limited to glossy live action by building an intentionally handmade visual and audio language.
View video prompt
Video: Create a 10-second 16:9 handcrafted stop-motion scene in a miniature farmhouse kitchen. A cheerful felt capybara wearing a tiny striped apron rolls noodle dough for the first three seconds, notices the dough sticking to its paw and pauses, then sprinkles flour too enthusiastically; a small white cloud settles over the table as it gives one amused chuckle. Warm moonlight and one amber lamp, tactile felt, wood, paper, and clay materials, visible frame-by-frame charm, consistent character proportions. Use two clear camera setups: a wide introduction followed by a close action-and-reaction shot. Native audio: wooden rolling pin, soft dough, flour puff, clock tick, tiny chuckle, and gentle plucked strings. No dialogue, text, logo, real character, or photoreal skin.
Turn a clear fact pattern into a visual mini-documentary
Use world knowledge and multiple shots for a useful explainer, then fact-check the result before publishing it as educational content.
View video prompt
Video: Create an 18-second 16:9 documentary-style explainer showing a fictional apartment building's rooftop rain garden during light rain. Shot 1: wide view of the planted roof receiving rainfall. Shot 2: clear cutaway-style visualization showing water passing through plants, soil, drainage layer, and storage channel; use simple shapes but no labels. Shot 3: the stored water slowly feeds a courtyard tree while excess water leaves through a safe overflow. Calm neutral camera, realistic building materials, diverse drought-tolerant plants, physically plausible water flow. Native audio: gentle rain, city ambience, soft drainage water, understated informative music. No presenter, narration, on-screen text, brand, dramatic flood, or unsupported quantitative claim. The final factual sequence must be reviewed by a human before publication.
How to prompt FLUX 3 Video
Write the clip as a timeline with an audible world
Longer duration is useful only when the prompt tells the model what changes and what must remain stable. Direct the opening state, chronological events, shot boundaries, camera behavior, dialogue, sound, and final state instead of stacking unrelated visual adjectives.
Define the anchors
Name the recurring person, product, wardrobe, location, style, format, and details that must survive every shot.
Sequence picture and action
Write shot 1, shot 2, and shot 3 in order, including camera movement, transitions, timing, and the final composition.
Attach sound to events
Quote dialogue exactly and connect ambience, Foley, effects, silence, and music cues to visible moments.
If the exact person, product, composition, or environment matters, prepare that visual first and animate it with Image to Video. Use Text to Video when FLUX 3 can invent the full scene more freely.
Practical model selection
Where FLUX 3 Video is especially useful

Frequently asked questions
FLUX 3 Video FAQ
What is FLUX 3 Video?
FLUX 3 Video is Black Forest Labs' multimodal AI video generation model. In Neurohelper AI it creates video from text prompts or source images and can generate synchronized dialogue, ambience, effects, and other audio with the frames.
How long can a FLUX 3 Video generation be?
Black Forest Labs documents clips up to 20 seconds in one generation. That is enough for a compact multi-shot story, ad, dialogue beat, or educational sequence without assembling only short fragments.
Can FLUX 3 Video animate an existing image?
Yes. The Image to Video route uses one source image to establish the opening person, product, composition, environment, lighting, or visual style. The prompt then directs movement, camera behavior, performance, and sound.
Should I use Text to Video or Image to Video?
Use Text to Video when FLUX 3 can invent the whole scene. Choose Image to Video when the exact product, character, composition, location, or visual direction needs to be established before motion begins.
Does FLUX 3 Video generate sound and dialogue?
Yes. Native audio can include dialogue, multilingual speech, ambience, Foley, and effects. For better results, quote spoken lines exactly and connect each sound to a visible event.
Is FLUX 3 Video available in Neurohelper AI?
Yes. FLUX 3 Video is available through Video Master in Text to Video and Image to Video modes, alongside other video, image, chat, voice, sound, and music models. Availability and usage limits depend on the selected plan.
