SkyReels-A2: A Generation Model for Assembling Arbitrary Visual Elements into Synthetic Video 132

What is SkyReels-A2?

SkyReels-A2 is a controllable video generation framework jointly developed by Skywork AI and Kunlun Inc. It can assemble arbitrary visual elements (such as people, objects, backgrounds, etc.) into synthetic videos based on text prompts. The videos are smooth and natural, and each element maintains strong consistency.

Main Features of SkyReels-A2

• Multi-element video generation: Generates high-quality, natural videos based on multiple reference images and text prompts.

• Strict consistency preservation: Ensures that each element in the generated video (such as people, objects, backgrounds) remains strictly consistent with the reference images.

• Controllable generation: Users can precisely control the content of the generated video through text prompts and reference images.

• Efficient inference: Optimized inference process that improves generation speed and output stability.

Technical Details of SkyReels-A2

• Joint image-text embedding model: A novel joint image-text embedding model is designed to inject multi-element representations into the generation process, balancing element-specific consistency with global coherence and text alignment.

• Data pipeline design: A comprehensive data pipeline is constructed to generate text-reference-video triplets for model training.

• Optimized inference pipeline: The inference process is optimized through various acceleration strategies (such as Context Parallel, CFG Parallel, and VAE Parallel) to improve generation speed.

• Public benchmark: A carefully curated benchmark called A2-Bench is introduced for systematically evaluating element-to-video (E2V) tasks.

SkyReels-A2 Application Scenarios

SkyReels-A2 has broad application prospects in creative fields, such as AI short drama creation, virtual e-commerce, and more.

• AI short drama creation: Creators can quickly generate personalized short dramas.

• Advertising and promotion: Enterprises can produce low-cost, high-quality advertising short films.

• Virtual e-commerce: Generate vivid product showcase videos.

• Game development: Quickly generate game storyline animations or character introduction videos.
