The Short Answer
Two resolutions, one frame rate, and a fifteen-second ceiling. If you only need the numbers they are all here; the rest of the page covers which one to pick and what it costs.
MiniMax H3 Max resolution is 480p or 768p. 768p is the default and the resolution the model was tuned around. At 16:9 that works out to 1344×768, and the frame rate is locked at 24 FPS regardless of which resolution you choose.
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.
One thing worth being precise about: H3 Max does not produce 2K. The base MiniMax H3 model does, and the two are separate models rather than two settings of one. The comparison further down lays out that split, and the MiniMax H3 Max AI video generator runs at both resolutions if you would rather just test it.
Every MiniMax H3 Max Resolution Option
There are only two resolutions to choose between, but the aspect ratio changes the pixel dimensions behind each one. Here is the full grid, plus the frame rate that never changes.
768p — the default
This is what H3 Max was tuned around, and it is what finished work should run at. At 16:9 it renders 1344×768. Every capability the model is known for — synchronized audio, prompt adherence, character consistency — was optimised at this resolution.
480p · 840×480
768p · 1344×768
480p — the draft tier
Half the cost per second, and useful for exactly one thing: finding out whether a prompt works before you spend 768p credits on it. Motion, timing, and audio all behave the same way; only the detail drops.
The six aspect ratios
| Ratio | Shape | Typical use |
|---|---|---|
| 21:9 | Ultrawide | Cinematic inserts, title beds |
| 16:9 | Landscape | YouTube, web, presentations |
| 4:3 | Classic | Retro and archival looks |
| 1:1 | Square | Feed posts, thumbnails |
| 3:4 | Portrait | Print-style verticals |
| 9:16 | Vertical | Shorts, Reels, TikTok |
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 option, and no setting that changes it — the H3 Max model renders at 24 either way. 24 is the cinema standard, which is why motion out of it reads as film rather than video.
What Each Resolution Is Actually For
The resolution choice is not really about quality — it is about which stage of the work you are at. Used as two steps, it makes a credit pack go roughly twice as far.
Draft at 480p
A prompt rarely works first time. Run three or four versions at 480p, listen to them, and find out which one holds. At 1 credit per second, four 5-second drafts cost 20 credits — the same as two finished 768p clips.
Finish at 768p
Once the prompt is right, run it once at 768p. This is the take you keep. Because H3 Max was tuned at this resolution, the difference is not only sharpness — prompt adherence and audio sync are at their best here.
When to skip 480p entirely
If you already know the prompt works — a format you have run before, or a small variation on a shot you shipped — go straight to 768p. The draft step earns its keep on new ideas, not on repeats. Both resolutions sit in the same dropdown when you generate an H3 Max video.
Which MiniMax H3 Max Resolution and Length to Pick
Most people over-think this. Here are four common jobs and the settings that fit each one, so you can copy the closest match and move on.
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.
Anything with dialogue
16:9 or 9:16, 768p, 8 to 15 seconds. Lip sync and voice quality are worth the full resolution, and dialogue needs the length to land.
H3 Max Resolution vs Base MiniMax H3
The H3 Max vs MiniMax H3 question comes down to one trade: the base model wins outright on resolution, and H3 Max wins on speed and price. These are two separate models, not two settings.
| H3 Max | MiniMax H3 (base) | |
|---|---|---|
| Resolution options | 480p, 768p | 768p base, 2K available |
| Max resolution | 768p | 2K |
| Frame rate | 24 FPS | 24 FPS |
| Clip length | 5–15 seconds | 5–15 seconds |
| Native audio | Yes | Yes |
| Render time, 5s clip | Under 3 seconds | ~35× longer on the official endpoint |
| Open weights | No — hosted only | Yes, downloadable |
Where H3 Max loses. If your deliverable has to be 2K, H3 Max cannot do it and the base model can. That is a hard ceiling, not a setting you can raise. The base model also ships open weights you can download and run yourself; H3 Max does not.
Where H3 Max wins. At 768p it returns a 5-second clip in under 3 seconds — fast enough that you iterate instead of waiting — and it costs less per second than the base model's own endpoint.
How to choose. Delivering at 768p or below, and want many takes: H3 Max — that is what this site runs, and you can try it at 768p on sign-up credits. Delivering at 2K: the base model, and accept the wait.
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
480p or 768p, chosen from the dropdown above the prompt box in the H3 Max generator. Pick 480p if you are still finding the prompt, 768p if this is the take you keep. This choice sets your credit rate for the whole generation — 1 credit per second at 480p, 2 at 768p.
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. Leave prompt expansion on balanced
Balanced decides per request how much to rewrite your prompt, which keeps the total time close to the render time. Fast returns in about a second; quality can spend up to 30 seconds rewriting before it starts. Balanced is the one to leave alone.
What Each Resolution and Length Costs
Credits are charged per second, and resolution is the only multiplier. Two rates cover everything, so once you know them you can price any clip before you generate it.
480p costs 1 credit per second. 768p costs 2. Nothing else is metered — aspect ratio, starting from an image, and the audio that comes back with every clip are all included.
| Clip length | At 480p | At 768p |
|---|---|---|
| 5 seconds | 5 credits | 10 credits |
| 10 seconds | 10 credits | 20 credits |
| 15 seconds | 15 credits | 30 credits |
So the longest clip H3 Max makes costs 30 credits at full resolution. The free 10 credits you get on sign-up cover one 5-second 768p clip, or two at 480p.

MiniMax H3 Max Resolution FAQ
Short answers first. These are the spec questions people actually search, and every figure is fal's published spec for the H3 Max endpoints, checked on 2026-08-28.
What is the MiniMax H3 Max resolution?+
MiniMax H3 Max renders at either 480p or 768p, with 768p the default and the resolution the model was tuned around. At a 16:9 aspect ratio, 768p works out to 1344×768 pixels at 24 frames per second. There is no higher option — 768p is a hard ceiling on this model, not a setting you can raise. If you need 2K output, that is the base MiniMax H3 model, which is a separate model with its own endpoints rather than a mode of H3 Max.
What is the maximum MiniMax H3 Max length?+
Fifteen seconds. MiniMax H3 Max length runs from 5 to 15 seconds in whole seconds, and the MiniMax H3 maximum duration for a single generation is 15. Anything longer means generating in segments and cutting them together afterwards, which works but costs you continuity across the joins. A 15-second clip at 768p uses 30 credits and takes roughly 15 seconds to render.
Does MiniMax H3 Max duration affect quality?+
No. MiniMax H3 Max duration changes what you pay and how long you wait, not how good the output looks. A 15-second clip holds the same resolution, frame rate, and audio quality as a 5-second one. What does change is how much can go wrong — longer clips give the model more beats to get right, so a long prompt that drifts is usually a prompt problem rather than a length problem.
How much render time does MiniMax H3 Max need?+
A 5-second clip at 768p comes back in under 3 seconds, which is faster than real time. Render time scales roughly with clip length, so a 15-second clip takes around 15 seconds. MiniMax H3 Max time is not affected by aspect ratio, and dropping to 480p speeds things up only slightly — the model is fast at both.
What frame rate does H3 Max output?+
24 FPS, locked, at both resolutions. There is no 30 or 60 FPS setting. Twenty-four frames per second is the cinema standard, which is part of why motion from H3 Max reads as film rather than as video. If you need a different frame rate, that is a conversion step in your editor after export.
Can H3 Max do 2K or 4K?+
No. H3 Max tops out at 768p natively. The base MiniMax H3 model reaches 2K, and the two are separate models rather than two settings of one — so switching to 2K means switching models, with the speed and price differences that come with it. For 4K, neither model produces it directly; that would be an upscale after export.
What aspect ratios does MiniMax H3 Max support?+
Six on text to video: 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16. On image to video the aspect ratio control does nothing, because the output follows the shape of the picture you upload — so if you need vertical output from an image, crop the image to 9:16 before uploading. The resolution setting is independent of the ratio, so you can pair 768p with any of the six.
