The AI video generation landscape shifted dramatically in early 2026. ByteDance's Seedance 2.0 arrived on Replicate with over 116,000 runs in its first three weeks, bringing native audio generation, multimodal reference inputs, and video editing capabilities that were previously split across multiple tools.
We've added both Seedance 2.0 and Seedance 2.0 Fast to the SkeletonAI platform alongside five other video models, giving creators seven options spanning every budget and use case. Here's what's new, how the models compare, and how you can try them for free.
What Is Seedance 2.0?
Seedance 2.0 is ByteDance's flagship video generation model, available on Replicate. It generates videos with synchronized audio from text prompts, images, video clips, and audio files.
Two variants are available:
- Seedance 2.0 (SkeletonAI Ultra) — Maximum quality for final renders. 150 credits per generation.
- Seedance 2.0 Fast (SkeletonAI Swift) — Faster output for prototyping and high-volume pipelines. 80 credits per generation.
Both support text-to-video and image-to-video, making them versatile for skeleton shorts production where you often start with a first-frame image.
Key Features
Native Audio Generation
This is Seedance 2.0's standout capability. Unlike most video generators that output silent clips, Seedance 2.0 automatically generates synchronized dialogue, sound effects, and background music alongside the video.
For dialogue, wrap speech in double quotes in your prompt:
She turned and said: "Follow me."
The model generates matching lip-sync and voice audio. For ambient sound, describe the scene naturally and the audio follows — footsteps, rain, crowd noise, whatever the visuals suggest.
This eliminates the need for a separate audio generation or voiceover step in your pipeline, which is especially valuable for skeleton shorts where you'd otherwise need to generate narration audio separately.
Multimodal Reference Inputs
Seedance 2.0 accepts multiple reference inputs simultaneously:
- Up to 9 images for character consistency and style guidance
- Up to 3 video clips for motion transfer and style reference
- Up to 3 audio files for audio-driven generation and lip-sync
Reference them in your prompt using labeled tags: [Image1], [Video1], [Audio1], etc.
Example prompt combining references:
The cat from [Image1] does the dance from [Video1] while the music from [Audio1] plays in the background.
This is powerful for skeleton shorts creators who want to maintain a consistent character across multiple videos — provide your character reference sheet as [Image1] and every generated scene stays on-model.
Video Editing and Extension
Seedance 2.0 can modify existing videos, not just generate new ones from scratch:
- Video editing: Provide a reference video and describe the changes you want. The model edits accordingly.
- Video extension: Continue an existing video with a text description of what comes next.
This is useful when a generated scene is almost right but needs adjustment — instead of regenerating from scratch, you can edit the specific part that needs fixing.
Resolution and Aspect Ratio
Seedance 2.0 supports two resolutions across six aspect ratios:
| Resolution | 16:9 | 4:3 | 1:1 | 3:4 | 9:16 | 21:9 |
|---|---|---|---|---|---|---|
| 480p | 864×496 | 752×560 | 640×640 | 560×752 | 496×864 | 992×432 |
| 720p | 1280×720 | 1112×834 | 960×960 | 834×1112 | 720×1280 | 1470×630 |
For TikTok, YouTube Shorts, and Instagram Reels, the 9:16 vertical format at 720p is the standard choice.
Model Comparison: Which AI Video Generator Should You Use?
SkeletonAI now offers seven video models. Here's how they compare:
| Model | Credits | Text-to-Video | Image-to-Video | Key Feature |
|---|---|---|---|---|
| SkeletonAI Lite (P-Video) | 25 | Yes | Yes | Most affordable |
| SkeletonAI Motion (Grok R2V) | 60 | — | Yes | Best for image animation |
| SkeletonAI Swift (Seedance Fast) | 80 | Yes | Yes | Native audio, fast |
| SkeletonAI Studio (MiniMax) | 100 | Yes | — | High quality text-to-video |
| SkeletonAI Ultra (Seedance 2.0) | 150 | Yes | Yes | Full multimodal, best quality |
| SkeletonAI Fast (Veo 3.1 Fast) | 250 | Yes | Yes | Google quality |
| SkeletonAI Pro (Veo 3.1) | 600 | Yes | Yes | Maximum quality |
How to Choose
For Lite and Trial users (500 credits/month): Start with SkeletonAI Swift (Seedance Fast) at 80 credits — you get about 6 videos per month with native audio included, which is exceptional value. If you're working with image-to-video, SkeletonAI Motion (Grok R2V) at 60 credits is the most affordable option for animating your first frames.
For Starter and Growth users (1,200–3,000 credits/month): SkeletonAI Ultra (Seedance 2.0) at 150 credits hits the sweet spot — full multimodal reference, native audio, and video editing. You get 8–20 videos per month, enough for regular publishing schedules.
For Business users (7,000 credits/month): Go with SkeletonAI Fast (Veo 3.1 Fast) at 250 credits for Google-quality output, or SkeletonAI Pro (Veo 3.1) at 600 credits when only the best will do. At this tier, you can produce 11–28 videos per month.
