Minimax H3
MiniMax H3 is MiniMax's latest omni-modal video model, and it's now fully available in Dreamerland. Unlike earlier video models that only read a text prompt or a single image, H3 understands text, images, video and audio together — you can hand it a prompt, a few reference photos, a video clip and a music track all at once, and it fuses them into a single coherent shot.
Every H3 clip comes with native audio generated together with the picture — dialogue, sound effects and ambience are created in the same pass, so there's no separate audio step and no audio toggle to worry about. Clips run from 4 to 15 seconds, and you can chain them together with the Extend task to build longer scenes.
Choosing a Task
There are 6 Minimax tasks in Dreamerland:
Text to Video
Image to Video
Extend Video
Text to Video
The classic starting point — describe the scene and H3 generates it from scratch, sound included. Because H3 generates audio natively, it pays off to describe what you want to hear as well as see.
Image to Video
Bring a still image to life. Upload a start frame, an end frame, or both:
Start frame only — the video begins from your image and animates forward.
End frame only — H3 generates a shot that lands exactly on your image.
Both — H3 creates a smooth transition between the two frames. Great for morphs, reveals and before/after shots.
The most powerful H3 task. Instead of using an image as the literal first frame, you feed H3 references and it builds a new shot around them:
Up to 5 reference images — lock a character's face, an outfit, a product or an art style.
A reference video — borrow motion, choreography or camera work from an existing clip.
A reference audio — drive the clip with a voice recording or sound. On H3, an audio reference alone is a valid job: upload a voice line and let the model perform it.
Extend Video
Continue a video you've already made. Upload the previous clip, choose how the extension should be driven (text, first/last frame, or reference), and H3 picks up where the clip left off — the extension automatically inherits the source clip's aspect ratio.
Turn on Merge source video if you want the result delivered as one combined clip (original + extension); leave it off to receive just the new part.
This is how you build stories longer than 15 seconds: generate a shot, extend it, extend again.
Edit an existing video with a text instruction — no manual masking needed. Upload the source clip and type a mask prompt describing what to change, e.g. "replace the red car with a white horse" or "change her jacket to a leather one".
Control type — None: the region is freely regenerated from your prompt.
Control type — Pose: the original motion is preserved while the appearance changes — perfect for swapping characters or outfits without losing the performance.
You can also attach up to 5 reference images to tell H3 exactly what the replacement should look like. The output keeps the source clip's length and aspect ratio.
Purpose-built for making videos cut to a song. Upload a full track (up to 5 minutes) and H3 generates a clip synchronized to it — visuals that move with the music.
Because each generation is still one 4–15 second clip, you build the full video piece by piece:
Upload your song and generate the first clip (elapsed length = 0).
For the next clip, set Elapsed video length to how many seconds you've already covered (e.g. 10).
Optionally attach the previous clip so the new one continues seamlessly from it — same characters, same scene, next part of the song.
Repeat until the song is covered, then stitch the clips in the built-in video editor.
Reference images and a reference video are optional here too, so your performer can stay consistent across every cut.
