Veo 3.1 vs Grok Imagine Video: 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.
Veo 3.1: A short scene with both picture and sound in mind, from rustling fabric to a character's line.
Grok Imagine Video: Animate a frame, try several ideas and build a clip lasting 6–30 seconds.
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.

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 Grok Imagine Video
Animate a frame, try several ideas and build a clip lasting 6–30 seconds.
Text or photos, 6–30 seconds, at 480p, 720p or 1080p.
Up to 7 photos at 480p and 720p; one at 1080p. Presentation modes include Normal, Fun and Spicy.
Presentation modes do not override service restrictions or guarantee particular content.
Inspect identity, clothing and props throughout longer clips.
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.
How should I compare Veo 3.1 and Grok Imagine Video 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.
