Overview

What MiniMax H3 Generator does

MiniMax H3 Generator is a web front end for H3, the video generation model made by MiniMax. It is not MiniMax's own product and says so: the site states it "is an independent third-party service. This website is not affiliated with, endorsed by, sponsored by, or operated by MiniMax." What it sells is browser access on prepaid credits, with no subscription. The interesting capability is the reference handling. Alongside text-to-video and image-to-video with first and last frame control, it accepts multimodal references: up to nine reference images, three videos totalling fifteen seconds, and three audio files totalling fifteen seconds, with the whole request capped at 64 MB. That is a lot more direction than a prompt box, and it is the reason to look at H3 rather than a model that takes text alone. Output is 768P or 2K, at four to fifteen seconds, which is a longer single clip than most competitors manage. Credits are charged per second of output: 9 a second at 768P and 14 at 2K. Packs run from $9.90 for 370 credits, which the site puts at about five five-second 2K videos, to $99.90 for 5,550, or roughly 79. New accounts get 50 starter credits, enough for about one short 768P clip, and purchased credits never expire.

What people use it for

Testing model output on free starter credits before paying

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about MiniMax H3 Generator.

It is not MiniMax's product. The model belongs to them and this site states no affiliation, so a change upstream arrives here without warning.
No operator is disclosed anywhere, only a support email, which is thin ground for a service taking prepaid money.
The 50 free credits buy roughly one short 768P clip, so the free tier demonstrates that it works rather than letting you evaluate it properly.
Reference input is capped at nine images, three videos and three audio files with a 64 MB total, which is generous for a prompt and restrictive for a real edit.
Prepaid credits are held by an unidentified vendor and nothing on the site says what becomes of an unused balance if the service stops.

Capabilities

Features

Text-to-video
Generates a four to fifteen second clip from a written prompt.
First and last frame control
Supply the opening and closing frames and let the model fill the motion between them, which is far more direction than a prompt alone.
Multimodal references
Accepts up to nine images, three videos and three audio files as references alongside the text, to guide motion, camera and style.
2K output
Renders at 768P or 2K, at 9 and 14 credits a second respectively.
Clips up to fifteen seconds
A longer single generation than most competitors, which reduces how much has to be assembled afterwards.
Free starter credits
New accounts get 50 credits, enough for roughly one short 768P clip, so the output can be judged before paying.

Answered, with sources

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

Is this the official MiniMax site?

No. H3 is made by MiniMax, and this site's own footer states it "is an independent third-party service. This website is not affiliated with, endorsed by, sponsored by, or operated by MiniMax."

Source

What does it cost?

One-off credit packs: $9.90 for 370 credits, $29.90 for 1,300, $49.90 for 2,500 and $99.90 for 5,550. New accounts receive 50 starter credits free and purchased credits never expire.

Source

How many credits does a video use?

Nine credits per second at 768P and fourteen at 2K. A five-second 2K clip is about 70 credits, which is why the site describes the $9.90 pack as roughly five of them.

Source

How long can a clip be?

Four to fifteen seconds, which is a longer single generation than most comparable services offer.

Source

What references can I supply?

Up to nine reference images, three videos totalling fifteen seconds and three audio files totalling fifteen seconds, with the whole request capped at 64 MB. First and last frame control is also supported.

Source

Is there a free tier?

Fifty credits on signup, which is about one short 768P clip. Enough to see the output quality, not enough to produce anything with.
