H3 Max Resolution, Duration, FPS & Aspect Ratios

The Short Answer

This site's generator has three resolution choices, one frame rate, and a fifteen-second ceiling. The rest of the page explains output sizing, framing, workflow, and site credit use.

On h3-max.com, MiniMax H3 Max offers 480P, 768P, and 1080P. At 16:9, 768P output is 1344×768 at 24 FPS. The 1080P option is available for delivery surfaces that require that output size.

MiniMax H3 Max length runs from 5 to 15 seconds, and 15 seconds is the ceiling for a single generation. There is no setting that produces a longer clip in one pass.

On text to video you choose from six aspect ratios: 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16. On image to video the output follows the aspect ratio of the picture you upload, so the framing decision is made when you pick the image.

The MiniMax H3 Max AI video generator on this site offers 480P, 768P, and 1080P output. It does not offer 2K or 4K in the current interface.

Every H3 Max Resolution Available on This Site

The local examples below cover 480P, 768P, and 1080P delivery sizes. Each video is labeled with its resolution, frame rate, duration, and source path so the output can be reviewed directly.

integrated_multimodal_description: [Shot 1] Live-action macro product cinematography, a medium-close shot frames an open antique brass pocket watch resting on charcoal linen beside a rain-speckled window. Fine concentric engraving, tiny gear teeth, the glass edge, and the woven fibers remain visible. The second hand advances smoothly while two exposed gears rotate at a steady rate. The camera performs an Arc Shot clockwise with small amplitude at slow speed, and a narrow strip of cool window light moves across the brass without changing the watch geometry. No hands enter, no dialogue, no visible text.

overall_soundscape: A precise mechanical tick repeats once per second above a soft, continuous gear whir. Light rain taps against the nearby window while the linen gives one faint rustle near the end.

480P — lower pixel dimensions

This setting is useful for prompt and motion tests where lower-resolution output is sufficient. It keeps the same 24 FPS output rate while reducing image dimensions.

768P — higher pixel dimensions

At 16:9, this setting produces 1344×768 output. Choose it when the higher available H3 Max resolution is appropriate for the delivery surface.

The six aspect ratios

21:9

16:9

4:3

1:1

3:4

9:16

Those six apply to text to video. On image to video, H3 Max follows whatever ratio your source picture has — so if you need 9:16 output from image to video, crop the image first.

Frame rate

24 FPS, locked. There is no 30 or 60 FPS output option, and no setting that changes it. Twenty-four frames per second is common in cinematic delivery, but frame rate alone does not determine whether a shot looks cinematic; camera movement, motion blur, lighting, and composition also shape that result.

Choosing Between 480P, 768P, and 1080P

Use 480P for fast composition and motion checks, 768P for standard delivery, and 1080P when the delivery surface requires a larger output frame.

Draft at 480P

Use short 480P iterations to check whether the prompt, camera movement, timing, and framing work together before selecting a final take.

Finish at 768P

Once the direction is settled, select 768P for the higher-resolution H3 Max output. The workflow examples below are displayed in full, without cropping their original frames.

When 768P is the better starting point

If you already know the prompt works, you can select 768P immediately. Open the H3 Max generator, choose 768P, and confirm the visible credit total before submission.

Suggested Starting Settings by Deliverable

These are editorial starting points rather than guaranteed best settings. Adjust the orientation, duration, and resolution to the actual delivery requirement and the motion the shot needs to contain.

Short-form social

9:16, 768P, 5 to 8 seconds. A feed clip does not need 15 seconds and rarely benefits from it. Keep it short enough that it loops cleanly.

Product and ad shots

16:9 or 1:1, 768P, 5 seconds. Product work lives on detail, so this is the one case where 480P drafting matters least — run it at 768P from the start.

Story beats and previz

21:9 or 16:9, 480P first, then 768P on the take you keep. Previz is where the draft-then-finish habit pays for itself, because you will run the same shot many times.

Dialogue-led shots

Start with the orientation required by the destination and give a short spoken line enough duration to finish naturally. Use 768P when facial detail matters, but evaluate lip synchronization and generated audio separately because output resolution does not guarantee better speech timing or sound quality.

How to Set Resolution, Length, and Aspect Ratio

The settings sit above the prompt box. Three of them matter, and one — the one most people get wrong — is worth leaving exactly where it is.

1. Pick the resolution first

Choose 480P, 768P, or 1080P from the resolution control in the H3 Max generator. The generator recalculates the visible credit requirement when you change it.

2. Set the length

Anywhere from 5 to 15 seconds, in whole seconds. MiniMax H3 Max duration is capped at 15 for a single run, so a longer piece means generating segments and cutting them together afterwards.

3. Choose the aspect ratio

Six options on text to video. On image to video this control does nothing — the output follows your source image — so crop the image before you upload it if the framing matters.

4. Choose prompt expansion deliberately

Prompt expansion affects how the submitted text is prepared; it does not change the selected duration, resolution, aspect ratio, frame rate, or site-credit rate.

H3 Max Site Credit Rates

These are h3-max.com site-credit rules. They are separate from external provider API charges and from the dollar price of a credit pack.

Reference-to-Video can add credits for reference inputs. See H3 Max Pricing and confirm the total shown by the generator before submission.
