## What Is SCAIL 2

SCAIL 2 is an end-to-end character animation model that transfers motion from a driving video to any reference character in a single pass. Unlike skeleton-based animation tools, SCAIL 2 encodes motion directly into latent space — it does not extract a skeleton from the reference character or remap pose data. This makes it work on characters that do not match a humanoid body schema: illustrations, animals, cartoon figures, and stylized art.

The model was trained on 60,000 motion training pairs and supports 4 animation scenarios. The SCAIL 2 model weights are open-source under Apache 2.0 at github.com/zai-org/SCAIL-2.

### Key Metrics

- 60K motion training pairs
- 4 animation modes (model); 2 available in this online tool
- 0 subscriptions required — one-time purchase only
- 15 free credits on sign-up

## Key Capabilities

**Skeleton-Free Motion Encoding**: Encodes motion directly from the driving video into latent space without extracting a skeleton. Works on any reference character regardless of body structure.

**Consistent Identity Preservation**: Maintains the visual identity of the reference character across every frame, even during complex motion sequences.

**Multi-Character and Group Scenes**: The underlying model handles group scenes with multiple characters simultaneously. (Not yet available in this online tool.)

**Zero-Shot Animal and Non-Human Animation**: Drives animal figures and non-humanoid characters from human driving videos without animal-specific training inputs. (Not yet available in this online tool.)

**In-Browser, No GPU Needed**: Everything runs in the browser. No Python, no CUDA, no local environment setup required.

**Open-Source and Commercially Licensed**: The SCAIL 2 model is Apache 2.0 licensed. Outputs generated through this tool can be used for commercial projects.

## How to Use SCAIL 2 Online — 4 Steps

1. **Upload your reference character** — Upload an image of the character you want to animate. Photos, illustrations, 2D art, and stylized figures all work. No skeleton or rig required.

2. **Upload your driving video** — Upload the video whose motion you want to transfer. This can be a human performer, a motion clip, or any video source. Cleaner, well-lit driving videos produce more consistent motion transfer results.

3. **Select animation mode** — Choose Animate to apply motion from the driving video to your reference character, or Replace to swap character identity in an existing video while preserving the original motion.

4. **Generate and download** — Click Generate. The model returns a video at your selected resolution (480p or 720p). Output length matches your input video — minimum 5 seconds, maximum 120 seconds. Download directly, no editing pipeline needed.

## Animation Modes

| Mode | Description | Available Online |
|------|-------------|-----------------|
| Animate | Apply motion from a driving video to a reference character | ✓ |
| Replace | Swap character identity in a video, preserving original motion | ✓ |
| Multi-Character | Handle group scenes with multiple characters simultaneously | Coming soon |
| Zero-Shot Animal | Drive animal figures using human motion, no animal training data | Coming soon |

## Credit Consumption

Credits are billed per second of output video, based on the length of the input driving video.

| Resolution | Cost | Notes |
|------------|------|-------|
| 480p | 2 credits / sec | Great for drafts and social content |
| 720p | 4 credits / sec | Recommended for most uses |

Output length matches input video — minimum 5 seconds, maximum 120 seconds.

### Examples

- 10-second clip at 480p = 20 credits
- 10-second clip at 720p = 40 credits
- 30-second clip at 720p = 120 credits

## FAQ

**What is SCAIL 2?**
SCAIL 2 is an open-source end-to-end character animation model released by Z.ai (Zhipu AI) in June 2026. It transfers motion from a driving video to any reference character without skeleton extraction or pose mapping.

**How is SCAIL 2 different from skeleton-based animation tools?**
Most animation tools extract a skeleton from the reference character and remap motion onto it. SCAIL 2 skips that step — it encodes motion directly from the driving video into latent space. This means it works on characters that don't match a humanoid body schema, including illustrations, animals, and stylized figures.

**Do I need to install anything or have a GPU?**
No. This tool runs SCAIL 2 in-browser. You don't need to install software, configure a Python environment, or own a GPU. Self-hosting the model weights requires a local GPU — see the official GitHub repo for requirements.

**What animation modes does SCAIL 2 support?**
This online tool currently supports two modes: Animate (apply motion from a driving video to your reference character) and Replace (swap character identity in an existing video while preserving the original motion). The underlying SCAIL 2 model supports four modes in total — multi-character scenes and zero-shot animal animation are not yet available in this tool.

**Can I use SCAIL 2 outputs for commercial projects?**
Yes. Videos generated through this site can be used for commercial purposes. There are no restrictions on using your outputs in ads, client work, content creation, or any other commercial activity.

**Can SCAIL 2 animate animals or non-human characters?**
Yes. This is one of SCAIL 2's specific capabilities — it can drive animal figures and non-humanoid characters from human driving videos in a zero-shot manner, without animal-specific training inputs. This capability is part of the full model; the current online tool focuses on Animate and Replace modes.

**Can I use a cartoon or 2D illustration as the reference character?**
Yes. SCAIL 2 does not require the reference character to match a humanoid skeleton, so 2D illustrations, cartoon characters, and stylized art all work as valid inputs.

**Is this site the official SCAIL 2 tool from Z.ai or Zhipu AI?**
No. This is an independent third-party online tool built on the open-source SCAIL 2 model. It is not affiliated with, endorsed by, or operated by Z.ai or Zhipu AI. The original model is available at github.com/zai-org/SCAIL-2.

**Do credits expire?**
No. Free and purchased credits both stay in your account with no expiry date.

**Can I get a refund?**
Yes — if you have used less than 10% of a purchased pack within 7 days of purchase. Contact support@scail2.com to request a refund.
