Astra 2

Enhanced creative upscaling for GenAI video with advanced control over detail and style

Model Overview

Astra 2 is an advancement in creative diffusion-based upscaling for GenAI video, building on Astra 1 with expanded control over detail generation and stylization. It transforms AI-generated footage by adding new, dynamic detail and texture, with adjustable creativity and sharpness controls and prompt-based guidance for more precise creative direction.

Astra 2 performs best on stylized and GenAI sources, as well as wide shots and large-scale scenes where additional detail can be creatively inferred. It enhances clarity, richness, and visual complexity, and is optimized for expressive, stylized workflows.

Key Capabilities

• Creatively transform GenAI sources with new detail and textures

• Expanded control with adjustable creativity and sharpness levels, plus prompt-based guidance
