Generate H3 Max video from a written shot or an opening image. Move from prompt to a synchronized 5-15 second clip at 480P or 768P with stronger instruction following and a fal-published render time faster than the video itself.
One low tracking shot follows a cobalt motorcycle through a concrete tunnel. White paper birds spiral in an exact clockwise helix, amber light maps the camera path, and engine tone, wing flutter, and tunnel reflections stay synchronized.

What is MiniMax H3 Max?
H3 Max is not simply a larger official MiniMax plan. fal Research continued training MiniMax H3's open weights and paired the resulting model with an inference stack designed around it.
fal says its post-training introduced substantial new data with an emphasis on prompt adherence and visual quality. The goal was to improve how accurately a shot follows ordered direction while preserving H3's unified video and native-audio foundation.
The inference engine was developed alongside the model rather than optimized afterward. fal reports that a five-second 768P generation completes in roughly three seconds, about 35 times the throughput of its standard H3 endpoint under the company's launch evaluation.
The quality claims are not limited to fal's internal comparisons. At the time of this page's research, H3 Max also appeared at or near the top of public image-to-video-with-audio preference boards. Rankings change as votes and competing models accumulate, so use them as evidence, not a permanent guarantee.
MiniMax H3 Max capabilities
Use MiniMax H3 Max as part of a complete AI video workflow in HighReach, from the first reference frame to final output review.
01Instruction fidelity
H3 Max was post-trained specifically around prompt understanding and aesthetics. Write chronological action, camera, lighting, and sound beats instead of relying on a short mood phrase.
02Faster-than-real-time iteration
fal publishes an under-three-second latency for a five-second 768P clip. That changes H3 Max from a model you wait on into a practical prompt-testing and shot-exploration loop.
03Unified audiovisual output
H3 Max retains H3's natively synchronized audio-video generation. Describe speech, room tone, foley, music, and intentional silence in the same chronological brief as the visible action.
Connected production
Brief, generate, compare, and refine without losing the creative thread.
How it works
H3 Max is strongest as a rapid creation and decision layer. Establish prompt, camera, motion, and sound at 480P or 768P, then keep the result or move to standard H3 when the project requires higher resolution or richer references.
Start from text for open exploration, or upload an image when subject appearance and composition are already decided.
Describe the opening state, ordered actions, camera path, lighting change, sound events, and final frame in sequence.
Use Balanced for fast everyday iteration, Disabled for exact wording, or Quality when a richer rewrite is worth additional preparation time.
Keep H3 Max when 768P is sufficient. Switch to standard H3 when you need 2K, 4K, video references, audio references, or localized editing.
Model lineup in HighReach
Text and image generation create a new 5-15 second clip with synchronized audio. Relight, Recast, and Extend start from a video you upload, and each has its own source-length limits.
Create the complete shot
Generate an original scene from written direction with six aspect ratios, selectable prompt expansion, and native audio.
Animate a visual anchor
Use a starting image as the source of truth and optionally add an end frame to control where the action resolves.
Change the lighting
Relight an uploaded clip from a lighting preset while keeping its subjects, motion, and camera. Each preset sends a lighting-sphere render that shows the target light.
Replace the people
Swap the main people in a clip for new characters from one to four photos, applied left to right in every shot where they appear. The source soundtrack is kept.
Continue the clip
Add 1-15 seconds of new footage after a clip and return the source plus the continuation as one video. H3 Max Turbo Extend offers the same workflow at a lower rate.
Prompt playbook
A useful prompt behaves like a compact director's brief. Give every detail a job instead of stacking visual adjectives.
Ordered action
010-2s: low tracking shot beside a cobalt motorcycle entering a concrete tunnel. 2-4s: white paper birds rise in one clockwise spiral without touching the rider. 4-6s: the camera pulls ahead and the rider crosses one amber light shaft. Preserve bike geometry and one continuous camera path.
Dialogue and sound
02Close handheld shot in a quiet workshop. The designer looks up and says, ‘Run it once more.’ Her lips stay synchronized and her voice is calm, close, and natural. Add a soft ventilation hum, one metal tool settling on the table, and no background music.
First and last frame
03Begin exactly from the uploaded wide product frame. The camera makes one smooth 35-degree clockwise arc as condensation forms and the key light warms from neutral to amber. End exactly on the supplied close label frame. Keep bottle shape, label text, cap, and background architecture stable.
Choose the right model
No single model is best for every brief. Compare the controls, cost and results that matter for your production workflow.

Check 01
H3 Max tops out at 768P. Use standard MiniMax H3 in HighReach when 2K or 4K output is required.
Check 02
H3 Max text and image generation does not take video or audio references; use H3 Max Reference for reference-led generation.
Check 03
Relight, Recast, and Extend each work on an uploaded clip. Relight accepts sources up to 15 seconds, Recast needs 5-30 seconds with no single shot over 15 seconds, and Extend accepts 1.6-60 seconds.
Check 04
For Relight, 1080P and 2K are upscaled and refined from 768P rather than generated natively.
Check 05
fal's latency and internal preference results are published provider measurements; actual queue time and independent leaderboard position can change.

Quality prompt expansion may spend up to roughly 30 seconds rewriting the brief before video inference begins.
MiniMax H3 Max FAQ
Practical answers about MiniMax H3 Max, available HighReach workflows, output controls, and prompt direction.
MiniMax H3 Max is a post-trained AI video model developed by fal Research from MiniMax H3's open weights. It focuses on stronger prompt adherence, visual quality, fast inference, and synchronized native audio.
MiniMax created the base H3 model and released its weights. fal Research used those weights for additional post-training and built the H3 Max variant and optimized inference stack. It is therefore a fal-developed variant of MiniMax H3, not a separate official MiniMax tier.
H3 Max is optimized for faster 480P and 768P text-to-video or image-to-video generation with improved prompt adherence. Standard H3 is the better HighReach choice when you need 2K or 4K output, image, video, and audio references, or reference-led editing.
fal reports that H3 Max can generate a five-second 768P video in roughly three seconds under its published launch evaluation. End-to-end time can still vary with prompt expansion, queue conditions, duration, and delivery.
HighReach exposes 5-15 second H3 Max clips at 480P or 768P. Text to Video supports six landscape, square, and portrait aspect ratios; Image to Video follows the uploaded image's composition.
Yes. H3 Max generates synchronized native audio with the video, including dialogue, ambience, sound effects, and music described in the prompt. The provider endpoint always includes audio rather than exposing a separate audio toggle.
Yes. The H3 Max image workflow accepts an opening image and an optional end image, allowing you to define both the starting composition and the destination of the motion.
fal's documented non-promotional list rates are $0.05 per generated second at 480P and $0.08 per second at 768P. HighReach bills in credits and displays the final generation cost before you run the model.
Yes. In HighReach, Relight Video applies a lighting preset to a clip of up to 15 seconds, Replace Character recasts one to four people from reference photos, and Extend Video adds 1-15 seconds of new footage and returns the full extended video.
fal's list rates are: Relight $0.05, $0.08, $0.16, or $0.32 per output second at 480P, 768P, 1080P, or 2K; Recast $0.30 per output second at 768P or $0.45 at 1080P; Extend $0.05, $0.08, $0.16, or $0.32 per generated second, and Turbo Extend $0.025, $0.04, $0.08, or $0.16. For a 5-second job, HighReach charges 800 credits for Relight at 768P, 3,751 for Recast at 1080P, 667 for Extend at 768P, and 400 for Turbo Extend at 768P.
Yes. Select MiniMax H3 Max in HighReach Text to Video or Image to Video. Choose duration, resolution, prompt expansion, and safety settings, then generate and review the result with your other media.
