In the current Mixer AI product, Seedance 2.5 extends the ceiling to 30 seconds, up to 30 images and up to 10 video plus 10 audio references; Seedance 2.0 tops out at 15 seconds, 9 images and 3 videos. The videos below tested the versions separately, so this is not a controlled quality A/B.

Seedance 2.5: up to 30 seconds, 30 images, 10 videos and 10 audio files; up to 1080p. Both reviews show strong multimodal-reference workflows and concrete failures: 2.0 had a background-audio conflict, while 2.5 showed morphing and reference confusion under a heavy input set. ## Specifications | Spec | Seedance 2.0 | Seedance 2.5 | Model variants | Mini / Fast / Pro | Seedance 2.5 | Generation modes | from text / from first and last frames / from references | from text / from first and last frames / from references / video editing | First frame | Yes | Yes | Last frame | Yes | Yes | Input photos | up to 9 | up to 30 | Input videos | up to 3 | up to 10 | Input audio files | up to 3 | up to 10 | Input video length | 2–15 s | 2–30 s | Input audio length | 2–15 s | 2–30 s | Output audio | Can be enabled or disabled | Can be enabled or disabled | Minimum duration | 4 s | 4 s | Maximum duration | 15 s | 30 s | Resolutions | 480p / 720p / 1080p / 4K | 480p / 720p / 1080p | Aspect ratios | 9:16 / 16:9 / 1:1 / 21:9 / 4:3 / 3:4 / adaptive | 9:16 / 16:9 / 1:1 / 21:9 / 4:3 / 3:4 / adaptive | Prompt limit | 20,000 characters | 30,000 characters | Price, 1 s · 1080p | ≈ 61.32 coins · Pro | ≈ 94.98 coins ## Seedance 2.0: reference motion and audio - The reviewer demonstrates image, video and audio references together, addressed through tags in the prompt. - Character motion transferred well from the video reference, but the separate audio file did not become background music: the model used sound from the source video instead. The reviewer suggests uploading a silent reference video as a workaround. - In another example, a reference video drove both camera and character action; the reviewer notes that the output followed not just camera movement but both characters' actions. ## Seedance 2.5: long scenes and reference load - In a 30-second scene, the reviewer tested complex motion and prompt adherence and noticed some morphing during the most intense motion-blurred moments. - With a large reference set, the model confused one character image and brought back an Arctic variant; the reviewer regenerated with the same inputs. - After pushing the reference limit, the reviewer says the maximum is usually unnecessary: a few character sheets, location stills and audio references are generally enough. ## What changes in Mixer AI The largest product-level change is duration and input capacity. Seedance 2.5 expands long-scene and multimodal-reference workflows. The separate 2.5 test also shows why more inputs do not automatically mean a more stable result. - 2.5 doubles the maximum duration: 30 seconds versus 15. - 2.5 accepts substantially more image, video and audio references. - 2.0 still exposes modes up to 4K in Mixer AI, while 2.5 is listed up to 1080p. ## What we compare [ Seedance 2.0 Up to 15 seconds; 9 images and 3 videos; video input; up to 4K in Pro. ](https://mixerai.org/en/knowledge/video/seedance-2/)[ Seedance 2.5 Up to 30 seconds; 30 images, 10 videos and 10 audio files; native audio; up to 1080p. ](https://mixerai.org/en/knowledge/video/seedance-2-5/) ## FAQ Is Seedance 2.5 always more stable than 2.0? These sources are not a direct A/B. The 2.5 review still showed morphing and reference confusion, so higher limits do not guarantee stability. What is the biggest Mixer AI difference? 2.5 reaches 30 seconds and accepts far more image/video/audio references. 2.0 tops out at 15 seconds but includes Pro modes up to 1080p and 4K. ## See also [Seedance 2.0 vs Kling 3.0 Turbo→](https://mixerai.org/en/knowledge/compare/seedance-2-vs-kling-3-0-turbo/)[Grok Imagine Video vs Seedance 2.0→](https://mixerai.org/en/knowledge/compare/grok-video-vs-seedance-2/)[Kling 3.0 Turbo vs Seedance 2.5→](https://mixerai.org/en/knowledge/compare/kling-3-0-turbo-vs-seedance-2-5/)[Seedance 2.5 vs Wan 3.0→](https://mixerai.org/en/knowledge/compare/seedance-2-5-vs-wan-3-0/) [Try it on Mixer AI](https://mixerai.org/?dl=kb_seedance-2-vs-seedance-2-5#/canvas)
