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.

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. ## Specifications | Spec | Seedance 2.5 | Gemini Omni 1.1 Flash | Generation modes | from text / from first and last frames / from references / video editing | from text / from first and last frames / from references / video editing | First frame | Yes | Yes | Last frame | Yes | Yes | Input photos | up to 30 | up to 7 | Input videos | up to 10 | 1, required | Input audio files | up to 10 | No | Input video length | 2–30 s | No | Input audio length | 2–30 s | No | Output audio | Can be enabled or disabled | No | Minimum duration | 4 s | 4 s | Maximum duration | 30 s | 10 s | Resolutions | 480p / 720p / 1080p | 360p / 720p / 1080p / 4K | Aspect ratios | 9:16 / 16:9 / 1:1 / 21:9 / 4:3 / 3:4 / adaptive | 9:16 / 16:9 | Prompt limit | 30,000 characters | 20,000 characters | Price, 4 s · 1080p | 403 coins | 42 coins ## 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 2.5 Build a short story, not just a moving picture: up to 30 seconds, recurring characters, your own references and sound. - Text mode starts without files. Frame mode uses a starting image and, optionally, an ending image. - Reference mode accepts up to 30 images, 10 videos and 10 audio files. Video and audio each have a separate 30-second total budget. - Timestamps guide pacing; they are not frame-accurate editing commands. - A large, conflicting reference set can work against you. Start with the few files that actually matter. ## 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. ## What we compare [ Seedance 2.5 Build a short story, not just a moving picture: up to 30 seconds, recurring characters, your own references and sound. ](https://mixerai.org/en/knowledge/video/seedance-2-5/)[ Gemini Omni 1.1 Flash Gemini Omni 1.1 Flash combines text, references, first/last frames, and video transformation in one variant. ](https://mixerai.org/en/knowledge/video/gemini-omni-1-1-flash/) ## FAQ How should I compare Seedance 2.5 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. ## See also [Seedance 2.0 vs Seedance 2.5: model comparison→](https://mixerai.org/en/knowledge/compare/seedance-2-vs-seedance-2-5/)[Seedance 2.5 vs Wan 3.0 Prime / Video: model comparison→](https://mixerai.org/en/knowledge/compare/seedance-2-5-vs-wan-3-0/)[Kling 3.0 Turbo vs Seedance 2.5: model comparison→](https://mixerai.org/en/knowledge/compare/kling-3-0-turbo-vs-seedance-2-5/)[MiniMax H3 vs Seedance 2.5: model comparison→](https://mixerai.org/en/knowledge/compare/minimax-h3-vs-seedance-2-5/) [Try it on Mixer AI](https://mixerai.org/?dl=kb_seedance-2-5-vs-gemini-omni-1-1-flash#/canvas)
