H3 video generator
with native audio
Create H3 video with a video generator that writes picture and sound in one pass — 4–15 second clips at 768P or 2K, with the exact credit cost shown before you submit.
Native audio — measured, not claimed
In H3 video, the audio is not laid on afterwards
MiniMax H3 writes picture and sound in one forward pass, so the two are aligned by construction rather than by editing. The H3 video below comes straight from this video generator: the waveform is measured from the delivered file, and the three prompt fields beside it are the exact text that produced it.

The prompt behind it
Forge settles- Pictureintegrated_multimodal_description
- [Shot 1] Live-action, cinematic, a medium shot frames a blacksmith in a dim forge, orange coal light across one side of her face and leather apron. The camera holds a static shot as she lifts a glowing bar from the fire with tongs, carries it to the anvil, and strikes it three times in an even rhythm, sparks scattering with each impact. [Shot 2] At 00:04.500, the shot cuts to a low close shot of the quench trough as she plunges the bar into the water; a violent burst of steam floods the frame and the glow dies from orange to grey, and the camera pulls out with small amplitude at slow speed as the steam thins and the forge settles back to low ember light.
- Soundoverall_soundscape
- Coals breathe with a low roar under the constant hiss of a bellows. Hammer strikes ring in a clear three-beat rhythm with a metallic decay after each blow, then the quench erupts into a sharp violent hiss that falls away into dripping water and settling steam.
- Scorenon_diegetic_music
- A low sustained drone at a slow tempo with a single struck metallic tone repeating at wide intervals, dropping out entirely at the quench.
The prompt asked for three hammer strikes in an even rhythm. Measured off the delivered file, they land 0.95 seconds apart at about 22 dB above the forge ambience, and the score drops out at the quench — which is what the third field asked for. The audio of this H3 video is the model’s own, copied without re-encoding.
Every field above is documented in the MiniMax H3 prompt guide, along with 28 copy-paste examples ready to drop into the H3 video generator, and the reason an empty audio field gives you a soundtrack the model picked rather than silence.
Made by us with MiniMax H3 — not stock footage
Three kinds of H3 video. One native-audio model.
Paper craft, a figurine turntable, macro ASMR — every H3 video on this wall is our own MiniMax H3 output, with sound and picture created in one pass. These previews are stripped of their audio so the wall can play silently; the clip you generate keeps the sound it was made with.

Each card opens the generator with the exact prompt behind that H3 video. The paper and ice clips use the three-field format documented in the prompt guide; the figurine turntable is a one-paragraph image-to-video prompt, so bring a still of your own.
Who it’s for
Who this H3 video generator is for
Every chip below is a real preset — open one and it arrives in the H3 video generator already written, sound fields included. Nothing is submitted until you press Generate.
Short-form creators
The format lives or dies on sound, and a clip you score afterwards never quite lines up. In an H3 video the audio arrives with the picture.
Product and ecommerce teams
A product shot needs controlled light, a controlled camera move and foley you chose. An H3 video writes that foley with the picture — no stock whoosh on top.
Directors and previz
You are testing whether a shot reads before anyone books a crew: the cut, the camera move and a line of dialogue must survive one short H3 video.
Explainer and course makers
A narrated piece falls apart when the style drifts or the voiceover fights the score, so both belong in the H3 video prompt, not the edit.
These are 11 of the 21 text-to-video H3 video presets. The prompt guide has the rest, grouped by technique: dialogue that survives a cut, a style that holds for a whole clip, and on-screen text that renders as letters.
Three H3 video generator workflows
The H3 video generator has three official workflows, and all three run here: text to video, image to video and reference to video. Every H3 video comes out with picture and stereo sound from a single pass. Prefer another model? The same video generator also runs Veo 3.1 and Veo 3.1 Fast, next to H3 video.
Text to video
Describe a shot and the model renders an H3 video with synchronized stereo audio in one pass.
You supply
A prompt.Image to video
Give the video generator a still and it becomes an H3 video that keeps the subject and framing you started from.
You supply
A first frame, an optional last frame, and a prompt describing the motion between them.Reference to video
Lock a character, a style or a motion from material you supply, then generate a new H3 video that keeps it.
You supply
Up to 5 reference images here (the model itself takes up to 9 images plus reference video and audio).Reference material is what the model matches against — it is not pasted into the output frame by frame.
Make an H3 video in three steps
- Step 1
Draft the prompt
Write one shot with a subject, an observable action, camera movement and intended audio. Nothing is submitted until you press Generate.
- Step 2
Price the exact request
Choose 4–15 seconds, an aspect ratio and 768P or 2K. The form calculates the exact credit reservation before submission.
- Step 3
Generate and download
Sign in, purchase credits, submit an allowed prompt, follow the task status and download the completed clip. Failed tasks return their reserved credits automatically.
Prompt structure is where many first H3 video attempts go wrong, and where a good H3 video prompt earns back its credits. The prompt guide has the subject → action → camera → audio structure the video generator responds to, with copy-paste examples you can load into the H3 video generator.
Tools
The video generator runs H3 video alongside Veo 3.1 and Veo 3.1 Fast; text to video and image to video have their own pages. Video to prompt works the other way round: hand it a reference clip and it writes the H3 video prompt that would recreate it, sound included.
Inside the H3 video model
The MiniMax H3 video model is omni-modal: an H3 video’s picture and stereo sound come out of one forward pass, so the audio lines up with the action. That single pass is what separates an H3 video generator from tools that add sound afterwards, and it is also why running the model locally takes far more than the quoted file sizes suggest.
The MiniMax H3 model page has the published specifications, an honest hosted-vs-local comparison, and all five technical guides — VRAM, ComfyUI, local setup, turbo LoRA and prompting.
Seeing clips finish before they can play through? Our plain-language H3 Max explainer separates fal’s faster hosted variant, the Turbo name and the “infinite video” demos.
If the channel is what brought you here, the Infinite Slop viewer’s guide explains where to watch and how suggestions enter the public queue.
H3 video frequently asked questions
Both terms describe this H3 video generator: a paid hosted workflow where one prompt renders picture and stereo audio together in a single pass, with the H3 video cost shown in credits before you submit.
No. The H3 video generator runs on remote hardware, so you do not need a local GPU. Running MiniMax H3 locally is a different matter: the official guidance calls for four GPUs, and even quantized community builds start around 8.5GB of weights before overhead.
Yes, and reference to video too — all three official H3 video workflows run here. Text to video takes a prompt alone; image to video takes a first frame and an optional last frame; reference to video takes up to 5 reference images on this site.
The current international MiniMax H3 V2 create API does not list a watermark parameter. Lightloom does not claim to disable a provider watermark and does not add its own; inspect each H3 video and the current MiniMax terms before publishing.
Yes, and it is not optional. The H3 video generator produces picture and stereo sound in a single pass, so leaving audio out of your prompt does not give you a silent clip — it gives you a soundtrack the model chose. Silence has to be requested explicitly.
The underlying model's weights are downloadable under the MiniMax H3 Community License, but hosted H3 video generation consumes paid compute. New accounts start with 150 welcome credits and a daily check-in adds 30 more; beyond these grants, packs start at $9.99 for 6,000 credits, and an H3 video costs 200 credits per second at 768P or 300 at 2K.
An H3 video can be about 15 seconds long at up to 2K and 24fps. For longer pieces, generate consecutive clips and edit them together rather than trying to stretch a single generation.
No. Lightloom is an independent guide and hosted workflow that uses the MiniMax H3 API; it is not affiliated with or endorsed by MiniMax. The official model announcement, API documentation and licensing terms live on MiniMax's own sites.
Commercial use can depend on the MiniMax terms, your input rights, the output itself and the platform where you publish it. Lightloom does not guarantee ownership or non-infringement; read the current source terms and review each H3 video before commercial use.
