AI video model by MiniMax
Try MiniMax H3 online: turn a text prompt or a single photo into a sharp 2K AI video of 4 to 15 seconds, with sound on every clip.
MiniMax H3 examples
Unedited MiniMax H3 outputs, each generated from a short prompt or a single image.
01Sound on every clip
MiniMax H3 always renders audio with the video; there is no silent mode. That makes it ideal for clips you post straight away: a dog barking at the door, a cheering crowd, waves crashing on rocks. Describe what should be heard in your prompt and the sound is generated to match the action.
02Realistic people and animal motion
Describe what a person or animal does, step by step, and H3 acts it out: a cat jumping onto a shelf, a dancer spinning, a child running toward the camera. Keep each action clear and physical, say which body part moves, and avoid cramming too many actions into one short clip.
032K resolution
H3 renders every clip in 2K, in both modes and at every length. With a single quality setting, you only choose the aspect ratio and duration. The extra detail holds up when a clip is cropped, zoomed or shown on a big screen, not just in a phone feed.
04Made for short social videos
Clips run from 4 to 15 seconds, enough for 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 land the payoff before the last second so it is not cut off.
05Animate photos in 2K
Add one image as the first frame and H3 animates from it, keeping your photo’s aspect ratio: vertical stays vertical, wide stays wide. Use it for a pet photo that comes alive, a still life with steam rising from a cup, or a portrait that turns toward the camera. The prompt only needs to describe motion and sound.
06Six aspect ratios in text mode
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 cinematic widescreen. Every ratio supports 4 to 15 seconds in 2K.

Short 2K clips, always with sound
Write who is in the clip, what they do, where the camera is and what we hear. For image to video, drop a photo into the first-frame slot; H3 keeps its aspect ratio and animates from it.
In text mode, pick one of six aspect ratios, then a duration from 4 to 15 seconds. Resolution is fixed at 2K and sound is always on, so there is nothing else to set.
Press Create; the button shows the credit cost before anything is charged. Sign in and top up only when needed, then download the MP4 or find it later in My videos.
MiniMax H3 is an AI video generation model from MiniMax. It creates short 2K clips from a text prompt or one starting image, and always renders sound with the picture. On Copy AI Video you can use it on this page or select it in the text to video and image to video tools, alongside Seedance 2.5, Seedance 2.0 and Kling 4.
From 4 to 15 seconds, with options of 4, 5, 6, 8, 10, 12 and 15 seconds. Credits are charged per second, so shorter clips cost less. For one continuous take longer than 15 seconds, switch to Seedance 2.5, which reaches 30 seconds at 480p or 720p.
Every H3 clip renders in 2K, at every length and in both modes. With a single quality setting, you only choose the duration, plus the aspect ratio in text mode. That is a clear step up from the 720p maximum of Seedance and Kling 4, 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”. For a silent clip, mute it in your editor, or use Seedance 2.0 or 2.5, where audio can be turned 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 its ratio, so there is no ratio setting; crop the image first if you want a different frame. Duration, resolution and sound are the same in both modes.
MiniMax H3 is priced per second, so the duration you pick sets the total, and the Create button shows the exact cost before you pay. Credits are sold in one-time packs and never expire. Failed renders are refunded automatically, so you only pay for finished clips.
Your photo is only used to render this video, and it is removed as soon as you delete the video. Finished clips stay in My videos, ready to replay or download. Upload only pictures you are allowed to use, and never someone else’s photo without their permission.
It depends on what you need. All three work from text or a first frame. MiniMax H3 renders 4 to 15 seconds in 2K and always includes sound. Seedance 2.0 offers 480p or 720p, 4 to 15 seconds, optional sound and a ratio choice in image mode. Seedance 2.5 offers 480p or 720p with clips up to 30 seconds.
Same prompt box, different strengths. Switch any time with the model button.
