MiniMax H3 Max - AI Video in Seconds with Native Audio & Lip Sync
MiniMax H3 Max generates a 5-second 768p video with synchronized audio in about 3 seconds — the #1 image-to-video model on the Artificial Analysis leaderboard. Try it online from 100 credits per clip.
MiniMax H3 Max Features - Speed, Lip Sync, Style Transform
What MiniMax H3 Max actually does differently: near-instant generation we measured at under 3 seconds of inference, dialogue with lip-synced voices, anime style transforms, and seed control the base H3 doesn't have. Every demo below was generated on this site and ships with its full prompt.
A 5-Second Video in About 3 Seconds
When we generated these demos, the API reported 2.77 seconds of inference for a full 5-second 768p clip — the video renders faster than it plays. The open-weights H3 that other hosts run averages ~82 seconds per request; most premium video models take 2-5 minutes. That speed makes iteration real: change a word, regenerate, see the result instantly. Prompt: 'A skateboarder in a sunlit concrete skatepark pops a crisp ollie over a rail, board snapping against the pavement on landing with a sharp crack, wheels rolling on rough concrete, dynamic low-angle tracking shot, golden hour light.'
Native Audio with Real Lip Sync
Write dialogue into your prompt and MiniMax H3 Max performs it — synced mouth movement, a matching voice, and ambient sound, all in the same pass as the frames. No TTS step, no post-sync. The barista really says the line: 'A friendly barista behind a wooden coffee bar looks straight at the camera, smiles warmly and says: "Your order is ready — one caramel latte, extra hot!" Steam rises from the cup, cozy cafe ambience with soft chatter in the background, close-up shot with shallow depth of field.'
#1 Image to Video on the Leaderboard
MiniMax H3 Max debuted at #1 in Image to Video and #3 in Text to Video on the Artificial Analysis leaderboards (with audio), ahead of the base MiniMax H3 it was trained from. In practice that means faithfulness: animated from a single photo, it kept her face, hair color, and the golden backlight. Prompt: 'The woman turns her head slowly toward the camera and smiles softly as a gentle breeze lifts her hair; golden grass sways around her in the warm sunset light.'
Style Transform Effects from One Photo
H3 Max was tuned for stylized transforms and can restyle a photo mid-shot. This clip starts from the exact same portrait as the demo above — same input, two completely different videos. Prompt: 'The scene magically transforms into hand-drawn 2D anime style: the woman and the golden field repaint themselves stroke by stroke into flat cel-shaded anime art with clean line work, her hair flowing in the breeze as sparkles drift across the frame, gentle magical chime sounds.'
Seed Control and First & Last Frame
Two controls the base MiniMax H3 doesn't offer: a seed parameter for reproducible generations, and an optional end image for first-to-last keyframe shots. Durations run 5-15 seconds at 480p or 768p — and you can open the Studio with MiniMax H3 Max already selected. Prompt: 'Rain-soaked neon-lit street in a cyberpunk city at night, a sleek hovercar glides past reflective puddles, holographic signs flicker in pink and cyan, camera tracks low along the wet asphalt.'
Where H3 Max Fits: Speed Tier of a Premium Family
MiniMax H3 Max is the fast lane: 768p with audio in seconds, built for iteration and effect content. Base MiniMax H3 is the quality lane: native 2K/4K plus 5-image reference-to-video. Wan 3.0 is the endurance lane: up to 30 seconds in one pass. All three run here on the same credits — draft on H3 Max, finish on H3 2K or Wan 3.0. Prompt: 'A golden retriever puppy shakes off water in slow motion on a sunlit beach at golden hour, water droplets sparkling in the air, gentle waves rolling behind, cinematic close-up, shallow depth of field.'
