Astra is a browser-based video enhancement tool from Topaz Labs for enlarging footage, including AI-generated video, to output up to 4K. Creative mode can reinterpret footage and add detail with Astra 1 and Astra 2. Precise mode focuses on preserving footage while sharpening and enlarging, with Starlight Precise 2.6, Starlight Fast 2, Proteus, Rhea, Nyx, and Iris models. Generative frame interpolation supports output up to 120 fps and slow motion up to 8×. Processing runs in the cloud using cloud credits, and batch processing is listed. Astra supports MP4 inputs using H.264 or H.265; another comparison page also lists AV1 and VP9 inputs, with H.264 MP4 exports. Astra 2 supports up to 9,000 frames without a prompt or 450 with one. Active subscribers’ renders are stored for seven days. Topaz says the Astra web interface became unavailable after September 30, 2026, with features moved to Topaz for Web.
