👋 Playground . 🔧 API Platform · 🤗 Hugging Face · 🤖 ModelScope · 📑 Technical Report
Welcome to the SkyReels V3 repository! This is the official release of our flagship video generation model, built upon a unified multimodal in-context learning framework. SkyReels V3 natively supports three core generative capabilities: 1) multi-subject video generation from reference images, 2) video generation guided by audio, and 3) video-to-video generation.
The demos above showcase videos generated using our SkyReels-V3 unified multimodal in-context learning framework.
# Clone the repository
git clone https://github.com/SkyworkAI/SkyReels-V3
cd SkyReels-V3
# Install dependencies (Recommended: Python 3.12+, CUDA 12.8+)
pip install -r requirements.txt
Models are available on Hugging Face and ModelScope:
| Model Type | Variant | Links |
|---|---|---|
| Reference to Video | 14B-720P | 🤗 Hugging Face / 🤖 ModelScope |
| Video Extension | 14B-720P | 🤗 Hugging Face / 🤖 ModelScope |
| Talking Avatar | 19B-720P | 🤗 Hugging Face / 🤖 ModelScope |
Note: By default, the script automatically downloads models from Hugging Face. To use a local path, specify it via the
--model_idflag.
Reference-to-Video is a model that synthesizes coherent video sequences from 1 to 4 reference images and a text prompt. It excels at maintaining strong identity fidelity and narrative consistency for characters, objects, and backgrounds.

💡 Notes:
- The
--task_typeparameter must be set toreference_to_video.- The
--ref_imgsparameter accepts 1 to 4 reference images. When providing multiple images, please separate their paths or URLs with commas.- The recommended output specification for this model is a 5-second video at 720p and 24 fps.
Extends existing videos while preserving motion continuity, scene coherence, and subject identity.

Running it yourself
Rent a machine by the hour. ComfyUI is installed on it. Open ComfyUI through the tunnel and load the workflow from the model's card on Hugging Face; choose this model's file in its loader.
# on your rented machine (the ssh line is on its page in the console)
# get REPO FILE FOLDER: one file into /workspace/models/FOLDER, where ComfyUI loads it from
get() { hf download "$1" "$2" --local-dir /workspace/hf-files && mkdir -p "/workspace/models/$3" && mv "/workspace/hf-files/$2" "/workspace/models/$3/$4"; }
# the model (5.3 GB)
