Video model by MiniMax
MiniMax H3 turns a prompt or a single image into a 2K clip of 4 to 15 seconds, and every clip comes with sound.
Examples
Clips MiniMax H3 made from a written prompt or one picture, played as they came out.
01Sound on every clip
MiniMax H3 always renders audio with the video; there is no silent version. That makes it a natural pick for clips meant to be posted as they are: a dog barking at the door, a crowd reacting, waves breaking on rocks. Describe what should be heard in your prompt, and the sound is made to match the action on screen.
02People and animals in motion
Write what a person or an animal does, step by step, and H3 plays it out: a cat jumping onto a shelf, a dancer turning, a child running toward the camera. Keep each action clear and physical, say which part of the body moves, and avoid stacking too many actions into one short clip.
032K output
H3 renders every clip in 2K, in both modes and at every length. There is a single quality setting, so the settings menu only asks for the shape and the length. The extra detail holds up when a clip is cropped, zoomed or shown on a large screen, not only in a phone feed.
04Short social clips
Lengths run from 4 to 15 seconds, which covers a reaction, a gag with a punchline, a product reveal or a looping background. Write one idea per clip, open on the subject so the first frame already tells the story, and put the payoff before the last second so it is not cut off.
05Photos into moving shots
Add one image as the first frame and H3 animates from it, keeping the shape of your photo: vertical stays vertical, wide stays wide. Use it for a pet photo that starts to move, a still life where steam rises from a cup, or a portrait that turns toward the camera. The prompt only describes the motion and the sound.
06Six ratios from text
Without an image, choose the frame yourself: 9:16 for TikTok, Reels and Shorts, 16:9 for YouTube, 1:1 and 3:4 for feeds, 4:3 for a classic look, or 21:9 for a wide cinematic strip. The same lengths from 4 to 15 seconds and the same 2K output apply to every shape you pick.

Short clips in 2K with sound on every one
Write who is in the clip, what they do, where the camera is and what we hear. For image to video, drop a photo on the first-frame slot; H3 keeps its shape and animates forward from it.
In text mode, pick one of six aspect ratios. Then choose a length from 4 to 15 seconds. Quality is fixed in 2K and sound is always on, so there is nothing else to set before you create.
Press Create; the button shows the credits for these settings before anything is charged. Sign in and top up only when you need to, then download the MP4 or find it again later in My videos.
MiniMax H3 is a video generation model from MiniMax. It makes short clips from a written prompt or from one starting image, and it always renders sound with the picture. On Copy That Video you can run it right on this page, or select it from the model menu on the text-to-video and image-to-video tools, alongside Seedance 2.0 and Seedance 2.5.
From 4 to 15 seconds. The length menu offers 4, 5, 6, 8, 10, 12 and 15 seconds. Credits are charged per second, so shorter clips use fewer of them. If you need one continuous take longer than 15 seconds, switch to Seedance 2.5, which goes up to 30 seconds at 480p or 720p.
Every H3 clip renders in 2K, at every length and in both modes. Because there is a single quality setting, the settings menu only asks for the length, plus the aspect ratio in text mode. That is a clear step above the 720p of the two Seedance models, which helps when a clip is cropped or shown on a big screen.
No. MiniMax H3 always generates audio with the video, so there is no audio switch while it is selected. You can still shape the sound in the prompt, for example “only rain and distant thunder, no music”. If you need a silent clip, mute it in your editor, or use Seedance 2.0 or 2.5, where audio can be switched off.
In text mode, H3 builds the whole scene from your words, and you choose one of six aspect ratios. In image mode, your photo becomes the first frame and the clip keeps the photo’s shape, so there is no ratio to pick; crop the image first if you want a different frame. Lengths, quality and sound are the same in both modes.
Each run is priced per second of video, so the length you pick sets the total, and the Create button shows the exact credits before you pay. Credits come in one-time packs and never expire. If a render fails, the credits are returned to your balance automatically, so you only pay for clips that finish.
The photo is kept only while the model works on it and is deleted as soon as the render ends, whether it succeeds or fails. The finished clip is saved to My videos for you to watch and download again. Only upload images you have the right to use, and never photos of other people without their consent.
All three work from text or from a first frame. MiniMax H3 renders in 2K, runs 4 to 15 seconds and always includes sound. Seedance 2.0 offers 480p or 720p, 4 to 15 seconds, sound you can switch off, and a ratio choice in image mode. Seedance 2.5 offers 480p or 720p with clips of up to 30 seconds.
Same prompt box, different limits. Switch any time from the model button.
