Description
Sunra AI Video Upscaler is a browser-based tool, part of the Sunra visual creation platform, that enhances video resolution up to 4K. Users upload a clip, pick a scale factor, and the AI reconstructs missing pixels and sharpens edges without needing any local software or a GPU.

The tool offers 2x or 4x scaling through five specialized AI models built on Topaz upscaling technology: Proteus for general footage, Artemis HQ for live action, Gaia HQ for CG and animation, Nyx for a balance of speed and quality, and Starlight HQ for high-fidelity enhancement. Beyond resolution, the AI reduces compression artifacts and grain from high-ISO footage and recovers texture in faces, text, and fine patterns. Processing preserves the original audio track and framerate, so the output is the same video with sharper visuals rather than a re-edited file.
Uploads accept MP4, MOV, and WebM files up to 500 MB each. Batch processing lets users queue up to 50 videos at once, with the number of concurrent jobs depending on the subscription plan. Because processing runs in the cloud, the tool works from any device with a modern browser, including Chromebooks and tablets, not just a Windows or Mac machine with a dedicated GPU. Sunra positions this against desktop upscaling software that requires installing an app and a dedicated GPU, and typically handles clips one at a time rather than in a batch queue.
Sunra gives every account free daily credits, enough to upscale a few clips without a credit card, and offers paid plans with more credits and priority processing for higher-volume use.
Typical uses include restoring old or low-resolution family and archival footage, upscaling drone and action-camera clips shot at 1080p or lower, preparing vertical social content for large screens, and sharpening the output of AI-generated video that comes out soft or low-resolution.
