In Mixer AI, Grok reaches 30 seconds and accepts up to 7 images, while Seedance 2.0 reaches 15 seconds but additionally accepts video references. [Try it on Mixer AI](https://mixerai.org/?dl=kb_grok-video-vs-seedance-2#/canvas) ## Key differences Grok in Mixer AI: text/image-to-video, 6–30 seconds, up to 7 images; 1080p allows one image. Seedance 2.0: text/image/video input, up to 15 seconds, up to 9 images and 3 video references. In the A/B, Grok did well in specific physics and text checks, while Seedance was clearly stronger on multi-step action, lip sync and storyboard adherence. ## Specifications | Spec | Grok Imagine Video | Seedance 2.0 | Model variants | Grok Imagine Video | Mini / Fast / Pro | Generation modes | from text / from references | from text / from first and last frames / from references | First frame | No | Yes | Last frame | No | Yes | Input photos | up to 7 | 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 | Extra modes | normal / fun / spicy | No | Output audio | No | Can be enabled or disabled | Minimum duration | 6 s | 4 s | Maximum duration | 30 s | 15 s | Resolutions | 480p / 720p / 1080p | 480p / 720p / 1080p / 4K | Aspect ratios | 9:16 / 16:9 / 1:1 / 2:3 / 3:2 | 9:16 / 16:9 / 1:1 / 21:9 / 4:3 / 3:4 / adaptive | Prompt limit | 5,000 characters | 20,000 characters | Price, 1 s · 1080p | ≈ 5.12 coins | ≈ 61.32 coins · Pro ## Physics and in-frame text - In the soccer-ball test, the reviewer liked Grok's physics even though the ball design distorted; in the following domino test, Grok failed while Seedance performed much better. - When animating a reference with lettering, Grok recognized and retained the text well in close-up; Seedance struggled more with the text in this check. ## Action, lip sync and multi-step structure - In the fight scene, Grok started convincingly but the motion broke down later; Seedance looked more realistic and added synchronized slow motion and sound. - In the lip-sync test, Grok added extra dialogue and mixed up speaker timing. Seedance tied speech, camera and emotion together more accurately, although text inside the scene remained a weakness. - On the complex storyboard, Grok failed to follow the requested sequence while Seedance preserved the structure much more consistently and added matching sound. ## Neutral reading of the test Grok's strong text result and one physics result did not repeat across every round. Seedance more often preserved long causal sequences inside the scene. Grok still has a concrete product-level distinction in Mixer AI: a 30-second maximum, versus 15 seconds for Seedance 2.0. - In-frame text: Grok led this particular test. - Complex storyboard and lip sync: Seedance led. - Maximum Mixer AI duration: 30 seconds for Grok, 15 seconds for Seedance 2.0. ## What we compare [ Grok Imagine Video Up to 30 seconds, text/image-to-video, normal/fun/spicy modes, up to 1080p. ](https://mixerai.org/en/knowledge/video/grok-video/)[ Seedance 2.0 Up to 15 seconds, text/image/video input, video references and a wider aspect set. ](https://mixerai.org/en/knowledge/video/seedance-2/) ## FAQ Which model followed the complex storyboard better? Seedance 2.0 followed the requested scene sequence much more accurately in this direct test. Which one preserved text in the reference better? Grok preserved the lettering better in that specific A/B. It is one observed test, not a guarantee for every text-heavy scene. ## See also [Seedance 2.0 vs Kling 3.0 Turbo→](https://mixerai.org/en/knowledge/compare/seedance-2-vs-kling-3-0-turbo/)[Seedance 2.0 vs Seedance 2.5→](https://mixerai.org/en/knowledge/compare/seedance-2-vs-seedance-2-5/) [Try it on Mixer AI](https://mixerai.org/?dl=kb_grok-video-vs-seedance-2#/canvas)
