What is MiniMax H3?
MiniMax H3 is MiniMax's video model, also sold under the Hailuo name. You give it a prompt or a photograph and it returns a moving shot at 2K. It is the successor to the Hailuo line rather than a variant of it.
On Kavel MiniMax H3 runs, and it never asks you to pick a resolution: the API accepts one value and returns 2K every time. That leaves one decision, how long the clip should be. A failed MiniMax H3 generation is refunded automatically, unless it broke the content policy.

How a run is billed
Per second of output at a single flat rate. No tier multiplier, no audio surcharge — the estimate moves only when the length does.
Resolution is not a choice
Most models here sell 720p, 1080p and 4K at different per-second rates. MiniMax H3 has a single output, so a draft and a final cut cost the same per second and differ only in length.
Length is the only lever
Because billing is per second and the resolution is fixed, duration is the entire cost equation. A ten-second clip costs twice a five-second one, and there is nothing else to trade against it.
The model's ceiling, and what runs here
MiniMax H3 accepts up to fifteen seconds in a single run, where several models on this site stop at eight or ten. The generator here offers 5, 6, 8 and 10 seconds.
Two ways in
Text-to-video and image-to-video both run on the same model here. Starting from a still is the more predictable of the two, because the opening frame is already settled before MiniMax H3 begins.
For a tier ladder including 4K, Kling 3.0 lets you pick the output; for a much cheaper draft pass, Seedance 1.5 Pro runs an order of magnitude lower per second.
When MiniMax H3 is the right pick
The reason to choose MiniMax H3 is usually that you do not want to think about output tiers at all.
You want one price to reason about
A single per-second rate means estimating a session costs you one multiplication rather than a table lookup.
You want more detail than 1080p
Every run returns a fixed 2K. Nothing else here goes past 1080p without moving up to a 4K rate, and there is no resolution to pick or get wrong.
You are animating a still
Image-to-video keeps the first frame you already approved, which removes most of the variance from the result.
What MiniMax H3 does
What it accepts and what it returns, taken from the provider's API documentation and this site's runtime configuration.
Text-to-video
Describe subject, motion and camera in one prompt and get a moving shot back at 2K.
Image-to-video
Supply a still and MiniMax H3 animates it instead of inventing a new scene around it.
First and last frame
Give MiniMax H3 a starting frame and an optional ending frame, so your shot begins with an approved image and has a destination from the start.
Aspect ratios
Text runs pick from 21:9, 16:9, 4:3, 1:1, 3:4 and 9:16. Image runs follow the aspect ratio of the picture you supply.
Prompts up to 2,000 characters
Enough room to name the subject, the camera move and what changes across the clip without compressing it into one line.
Cost shown per run
The credit estimate reflects the exact length you picked, and length is the only input that changes it.

Generating with MiniMax H3
Four steps, and because resolution is fixed, only one of them moves the price.
Pick text or image to video
Starting from a still removes most of the variance, because the opening frame is already settled.
Choose the length
This is the whole cost decision here. Five seconds to judge an idea, longer once the shot is settled.
Set the aspect ratio
Text runs need one chosen up front. Image runs inherit it from the picture, so there is nothing to set.
Write the motion, then generate
Name the camera move and what changes across the clip. The estimate updates before you commit.
What people make with MiniMax H3
Four jobs where a fixed 2K output and a longer maximum are the reasons MiniMax H3 gets picked.
Social clips at one quality
No tier decision per post — every run comes back at the same resolution, so a batch looks consistent.
Product shots in motion
Animate an approved still so the framing and the product stay exactly as they were signed off.
Footage you will crop or blow up
A 2K master survives a reframe, a vertical crop or a full-screen cut without going soft the way a 1080p source does.
Concept passes before a shoot
A five-second run is cheap enough to explore several directions in one sitting.

Questions about MiniMax H3
What it costs, what it accepts and where it stops.
MiniMax H3 is billed per second at a single flat rate, so length is the only thing that moves the number. A five-second clip is about 395 credits on this site and a ten-second clip about 790. The generator shows the estimate before you start, and a failed run is refunded automatically unless it broke the content policy.
No, and that is a property of MiniMax H3 rather than a limit we imposed. The API accepts one resolution value and returns 2K, so there is no tier selector on this page. If you need to pick an output tier — including 4K — Kling 3.0 sells three of them.
Yes — all three name one model. MiniMax ships it as both MiniMax H3 and Hailuo H3, the version is also written Hailuo 3.0, and the provider we run it through lists it as Hailuo 03. Anything written under any of those names describes MiniMax H3 you are generating with here.
MiniMax H3 accepts whole-second durations from five to fifteen seconds. The generator on this site offers 5, 6, 8 and 10 seconds; four seconds is not available, because five is MiniMax H3's floor rather than a rounding choice.
Yes. Image-to-video takes a still and animates it, and it also accepts an optional ending frame if you want to say where the shot should arrive. Aspect ratio is inherited from the image in this mode, so there is nothing to choose. Switch to the Image to video tab in the generator.
We cannot source an answer to that, so this page does not claim one either way. The provider documentation describes audio you can supply as a reference input, which is a different thing from audio MiniMax H3 produces, and we will not read one as the other.
Commercial rights follow your Kavel plan rather than MiniMax H3 in particular, so check the pricing page for what your tier includes. Nothing on this page grants rights the plan does not.
Not through Kavel. This page is the hosted version: you send a prompt or a photo and get a finished clip back, with the credit cost shown before you commit. There is no local install, no GPU requirement and nothing to download on this side.
MiniMax H3 renders everything at 2K — there is no lower tier to fall back to — so detail-heavy, identity-consistent shots are its lane. Seedance 2.5 wins on take length — up to 30 seconds. Pick by which constraint your shot actually has.
