SkyReels-V3 - Kunlun Tech's open-source multimodal video generation model

What is SkyReels-V3?

SkyReels-V3 is an open-source multimodal video generation model from Kunlun Wanwei, enabling professional-grade video creation with a single architecture. The model can transform static images into dynamic footage, supports intelligent video length extension and cinematic transitions, and ensures precise audio-visual synchronization of digital humans. The model surpasses mainstream commercial products in key metrics such as character consistency and image quality, marking a new era of high-fidelity, multimodal AI video generation and providing creators with a one-stop solution for everything from short clips to long narratives.

Main functions of SkyReels-V3

• Reference Image to VideoGenerate high-quality dynamic videos with coherent timelines and complete feature preservation based on 1-4 reference images.
• Video extensionIt supports single-shot continuity and five professional film transitions, achieving an upgrade from time extension to narrative extension.
• Audio-driven virtual avatarsIt generates synchronized digital human videos based on a single portrait and audio, supporting minute-long videos and multi-role dialogues.

The technical principles of SkyReels-V3

• Image to videoDynamic materials are selected through a cross-frame pairing strategy. An image editing model is used to extract the subject, complete the background, and rewrite the semantics, avoiding "copy-paste" artifacts. The model uses unified encoding to fuse textual and visual information from up to four reference images. Robustness to different sizes and aspect ratios is improved through image-video hybrid training and multi-resolution joint optimization.
• Video extensionThe innovative unified multi-segment position coding technology accurately models motion trajectories in complex sequences. The model achieves smooth shot transitions through a hierarchical hybrid training strategy, solving the "jump" problem of traditional extended shots. At the same time, the built-in intelligent shot transition detector automatically identifies transition points and supports five professional film transition techniques.
• Virtual avatarBased on the regional routing mechanism, it achieves precise audio and video alignment, allows specific characters to speak, and adopts a keyframe constraint generation strategy to first construct equally spaced keyframes to determine the action framework, and then fill the intermediate frames with keyframes and audio as constraints to achieve stable generation of minute-long videos.
