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.

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. ## Specifications | Spec | Seedance 2.5 | Grok Imagine Video | Generation modes | from text / from first and last frames / from references / video editing | from text / from references | First frame | Yes | No | Last frame | Yes | No | Input photos | up to 30 | up to 7 | Input videos | up to 10 | No | Input audio files | up to 10 | No | Input video length | 2–30 s | No | Input audio length | 2–30 s | No | Extra modes | No | normal / fun / spicy | Output audio | Can be enabled or disabled | No | Minimum duration | 4 s | 6 s | Maximum duration | 30 s | 30 s | Resolutions | 480p / 720p / 1080p | 480p / 720p / 1080p | Aspect ratios | 9:16 / 16:9 / 1:1 / 21:9 / 4:3 / 3:4 / adaptive | 9:16 / 16:9 / 1:1 / 2:3 / 3:2 | Prompt limit | 30,000 characters | 5,000 characters | Price, 1 s · 1080p | ≈ 100.51 coins | ≈ 5.41 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 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. ## 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/)[ Grok Imagine Video Animate a frame, try several ideas and build a clip lasting 6–30 seconds. ](https://mixerai.org/en/knowledge/video/grok-video/) ## FAQ How should I compare Seedance 2.5 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. ## See also [Grok Imagine Video vs Seedance 2.0: model comparison→](https://mixerai.org/en/knowledge/compare/grok-video-vs-seedance-2/)[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/) [Try it on Mixer AI](https://mixerai.org/?dl=kb_seedance-2-5-vs-grok-video#/canvas)
