Seedance 1.5 Pro vs Gemini Omni 1.1 Flash: 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.
Seedance 1.5 Pro: Animate a portrait, show a product or connect two frames in a short scene with sound.
Gemini Omni 1.1 Flash: Gemini Omni 1.1 Flash combines text, references, first/last frames, and video transformation in one variant.
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 Seedance 1.5 Pro
Animate a portrait, show a product or connect two frames in a short scene with sound.
Text mode needs no files. Image mode takes a starting frame and an optional ending frame.
Mixer AI offers 4, 8 or 12 seconds at 480p, 720p or 1080p.
Two images are the limit; this model page does not use separate video or audio references.
Incompatible poses or different objects at either end can produce morphing rather than believable movement.
What to inspect with Gemini Omni 1.1 Flash
Gemini Omni 1.1 Flash combines text, references, first/last frames, and video transformation in one variant.
From text, 1–7 image references, first/last frames, or source-video transformation.
New clips: 4, 6, 8, or 10 seconds; 360p, 720p, 1080p, or 4K; 16:9 and 9:16.
The first/last-frame workflow cannot be mixed with the ordinary image-reference set.
Video transformation works on a selected segment up to 10 seconds and does not treat the new-clip duration selector as a promise for edited output length.
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 Seedance 1.5 Pro and Gemini Omni 1.1 Flash 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.
