MiniMax H3 Ref2V
The full-reference composer every recipe here renders on: you brief the scene, camera, dialogue, and sound in the prompt, then anchor it with up to 9 reference images, 3 short video clips, and 3 standalone audio files (12 files total). H3 re-performs your subject and ships a synchronized stereo soundtrack in the same pass, at 768P or 2K, landscape or portrait.
What a prompted clip costs
Hosted prompting is the service; the model run is the cost. H3 bills per clip in Moosky credits (100 to the dollar): about 10 credits per output second at 768P and 18 at 2K, plus any reference-video seconds and images past the first five. The composer quotes your exact total before anything renders, and failed runs refund.
Why use it on Moosky AI
Powerful tools. Seamless experience.
The six-section brief
Write subject definitions, a summary, retention notes, a detailed description, an overall soundscape, and a music cue — the structure H3 follows when it reads a prompt.
Slots that get named jobs
Give every reference a role in the text: Image 1 the face, Video 1 the move, Audio 1 the voice, Subject 1 the reusable character. Order defines the label.
Dialogue written like a script
Quote the line in a tagged span with its language; H3 lip-syncs it to the picture with stereo ambience and score, no dubbing step.
Camera verbs in plain words
Name the move — Push In, Pan, Truck, Arc, Static — with its speed and amplitude; H3 reads plain-language direction, not keyword lists.
Delta-edit the winning take
Attach the approved clip as Video 1 and prompt only what changes; the transferred performance carries and you pay for output seconds once.
Cost before you run
Wondering what a 2K H3 clip costs? The composer shows the credit price for your exact bundle first; drafts at 768P stay cheap.
How It Works
Three simple steps to finished output
Load and label the kit
Attach your references and fix their jobs in order — face still, style frame, the motion clip as Video 1, an optional voice take as Audio 1. Stay under 12 files and 15 reference-video seconds.
Write the brief, cite the files
Fill the six sections, name the camera verb, quote the dialogue, and reference each file by its label so the model knows what to transfer and what to invent.
Check the quote, render, refine
The composer shows the credit cost first; draft at 768P, confirm the transfer reads, then rerun the keep at 2K or delta-edit it from the approved clip.
A prompt manual for the reference-to-video lane
This page is the working prompt manual for MiniMax H3's reference-to-video lane, not another spec sheet. The model page carries the capability list and the family heads; the matchup compares H3 against other engines on one balance. Here the job is the brief itself: how to structure the six-section prompt, how to label each Image, Video, and Audio slot so the model transfers exactly what you intend, and how to phrase dialogue and camera so a clip comes back usable on the first or second render.
The reason labels beat adjectives is how H3 reads a reference kit. Assign every file an explicit job in the text — Image 1 the face, Video 1 the movement, Audio 1 the voice, Subject 1 the reusable character — and a bad take becomes one swapped file instead of a rewritten paragraph of style words. Order in the upload is the label in the prompt, so the roles stay stable across every section you write.
Then direct like a brief, not a keyword list. Name the camera as a plain verb with its speed — a slow push in, a locked static, an arc — quote the spoken line inside a tagged span with its language so the stereo dialogue lip-syncs to it, and spend your detail across the clip's whole duration instead of stacking adjectives on the first frame. That is the difference between a clip that feels directed and one the model simply guessed.
Every recipe on this page runs on the live H3 Ref2V composer on Moosky, so you paste one in, watch the credit price appear, then escalate a good 768P draft to a 2K final or delta-edit the approved take without re-rendering. For the full step-by-step build — reference sheets, tuning the transfer, the editing loop — the workflow guide below is the deeper how-to; this page is where you load the kit and hit generate.
Credit-based
Simple, honest pricing
H3 Ref2V clips bill in credits (100 per $1): about 10 per output second at 768P and about 18 at 2K, plus your reference-video seconds at the chosen output resolution and any images past the free first five. The composer quotes the exact total before you run, and failed generations refund automatically.

Frequently Asked Questions
How do you write a MiniMax H3 Ref2V prompt?
Fill the six sections in order — subject definitions, a one-line summary, a retention note per reference, a detailed description of shots and actions, an overall soundscape, and an optional music cue. Give every attached file an explicit job and label (Image 1 the face, Video 1 the movement, Audio 1 the voice), name the camera as a plain verb with its speed, and quote any spoken line inside a tagged span with its language. Plain direction outperforms keyword lists.
What does each reference slot do in H3?
References are ordered, and their position in the upload is their label in the prompt. Images carry identity, wardrobe, and style; the first video carries the movement and camera feel you want transferred; standalone audio carries voice timbre. Up to 9 images, 3 video clips, and 3 audio files are allowed with a 12-file ceiling, and at least one visual must anchor the render — audio alone cannot be the only input.
How many reference files can a single H3 prompt use?
Up to 9 reference images, 3 reference videos, and 3 standalone audio clips, with 12 files total as the hard cap. Each video and audio clip runs 2-15 seconds and the combined reference-video seconds stay under 15. A standalone audio file must accompany at least one image or video so the model always has a visual first frame.
Can MiniMax H3 write its own dialogue in a clip?
Yes — write the spoken line the way a script reads, tag it with the language, and H3 lip-syncs it into the picture with synchronized stereo ambience in the same render pass, across the model's supported dialogue languages. Keep the clip short enough that the line lands, and prefer the voice-transfer route when you already have a take you want kept.
How do I transfer a camera move from a clip instead of describing it?
Upload the exact movement as Video 1 — a walk, a steadicam push, a product turn — trimmed to the seconds where the move is isolated, then confirm it in the brief with a sentence like a named push in matching Video 1. The clip demonstrates amplitude and speed text cannot, so showing it beats describing it. When the scene content changed a lot, pair the clip reference with a plain-language camera verb so the transfer is not read loosely.
How much does an H3 Ref2V clip cost to run?
In Moosky credits, at 100 to the dollar, scaling with clip length and resolution: about 10 credits per output second at 768P and about 18 at 2K, plus every second of your reference video billed at the output resolution you pick and any images beyond the free first five. The composer shows the exact total for your bundle before anything renders, and failed generations refund automatically — there is no subscription.
Which resolution should I prompt at first?
Start at 768P for drafts — it is H3's native short-edge around 768 and cheap to iterate, so you can rough a whole sequence and check that the motion and identity transfers read. Escalate only the take that works to 2K, whose short edge is 1440, for the delivery file. That ladder is the cheapest way to converge on a final without paying full rate on every experiment.
Can I fix one thing in a rendered clip without re-rendering?
Yes — attach the approved clip as Video 1 and prompt only the change while naming what to preserve, so the performance and transferred movement carry and you pay for output seconds once instead of rebuilding from the reference sheet. This is generative editing, not a video editor: it cannot cut, trim, or speed-ramp, so restart from the sheet when the scene concept itself was wrong.
Do the prompts here run on the current H3 model?
Yes. Every recipe renders on the live MiniMax H3 Ref2V composer on Moosky, which is the same full-reference engine with native stereo audio and the ordered Image, Video, Audio, and Subject labels the six-section brief cites. Paste a recipe into the composer, adapt its wording to your files, and see the credit price before you run it.
What is the difference between this prompt guide and the workflow guide?
This page is the tool lane: a commercial prompt recipe library that sells the reference-to-video composer and deep-links you into it so you can run the six-section brief and watch the cost first. The sibling workflow guide keeps the informational how-to — building the reference sheet, tuning the transfer, running delta edits step by step. Read the guide to learn the method, then load your kit and generate from here.
