What is Astra 2?
If you’re new here: Astra 2 targets AI-generated and stylized video. Plain upscaling mostly enlarges and sharpens existing pixels; Astra 2 can add plausible new detail and texture where the source is soft, so the clip feels richer, not only bigger.Model overview
It builds on Astra 1 with clearer control over how detail and stylization are produced (creativity, sharpness, optional descriptive prompts, not step lists). Strong fits: stylized/GenAI footage, wides and sparse-detail scenes, and footage that looks overly smooth until texture is restored.What Astra 2 is good at
- Adds texture and detail: Not only sharpening.
- Steerable look: Creativity, sharpness, optional prompt guidance.
- Stylized & wides: Where inferred detail matters.
