Veo 3.1 vs MiniMax H3: technical and visual comparison

This compares two models that are available in the current Mixer AI catalog. The table below is built from current product controls, while the visual section shows what to inspect with the same inputs and prompt instead of inventing one universal winner.

Key differences

Veo 3.1: A short scene with both picture and sound in mind, from rustling fabric to a character's line.

MiniMax H3: Build a scene from separate references for appearance, movement and sound.

Start with the specification table: it reflects current modes, input media, duration, resolution, aspect ratios and a normalized price where a fair comparison is possible.

Specifications

Spec	Veo 3.1	MiniMax H3
Model variants	Lite / Fast / Quality	MiniMax H3
Generation modes	from text / from first and last frames / from references	from text / from first and last frames / from references
First frame	Yes	Yes
Last frame	Yes	Yes
Input photos	up to 3	up to 9
Input videos	No	up to 3
Input audio files	No	up to 3
Input video length	No	2–15 s
Input audio length	No	2–15 s
Output audio	Native	Native
Minimum duration	4 s	4 s
Maximum duration	8 s	15 s
Resolutions	720p / 1080p	768p / 2K
Aspect ratios	9:16 / 16:9 / auto	9:16 / 16:9 / 1:1 / 4:3 / 3:4 / 21:9
Prompt limit	1,000 characters	7,000 characters
Price (different settings)	21 coins · 4 s · 720p	43 coins · 4 s · 768p

There is no shared resolution for a direct price comparison, so each price includes its setting and is not highlighted as cheaper.

What to compare visually

For a fair A/B test, use the same scene and, where both modes allow it, the same first frame. Inspect motion continuity, character and object consistency, physics and contacts, camera behavior, temporal deformation, in-clip cuts and audio synchronization.

What to inspect with Veo 3.1

A short scene with both picture and sound in mind, from rustling fabric to a character's line.

Lite, Fast and Quality are separately priced versions. Test the idea with an affordable option, then compare another version using the same brief.
Text mode needs no images. Frame mode takes a first image and an optional last one. Reference mode accepts 1–3 photos for subjects, products and the scene.
Review written signs and pronunciation separately from the visual quality.
Very different first and last frames can produce an awkward transformation rather than a believable transition.

What to inspect with MiniMax H3

Build a scene from separate references for appearance, movement and sound.

Text mode, one or two frames, or references.
Up to 9 images, 3 videos and 3 audio files. Video and audio each have a separate 15-second total limit; audio needs a visual reference.
The first five images are included in the base calculation; additional images increase the price.
Input video adds billable duration. Check the total, not only the resolution.

How to run a fair comparison

Lock one prompt, aspect ratio and a duration or resolution that both models actually support.
If input modes differ, compare the shared workflow first and test each model's extra controls separately.
Run more than one attempt: a single output reflects one seed, not the model's overall consistency.
Score prompt adherence, visual artifacts, reference preservation and the cost of the setting you would really use separately.

FAQ

How should I compare Veo 3.1 and MiniMax H3 fairly?

Use a workflow both models share, keep inputs and prompt identical, then run several generations. Compare prompt adherence, visual consistency and the price of the setting you need as separate dimensions.

Are both models available in Mixer AI?

Yes. This page is generated only for models in the current public Mixer AI catalog; if a model leaves the catalog, the automated comparison must stop passing validation.

Which model is better?

There is no universal answer. First eliminate a model that cannot accept the input, duration, resolution or format you need, then compare outputs on your own scene. The table highlights only measurable advantages in individual specifications.
