FAQ

About Topaz Video Upscale API

A required video_url, an optional upscale_factor (1.25, 1.5, 2, 3, or 4 - defaults to 2), and an optional target_fps. Leave target_fps on "Same as source" and the playground omits it from the request, keeping the input frame rate.

Choose "Same as source" for Target FPS. The playground will not send target_fps, and the API falls back to the source video's native FPS.

The API accepts 1.25, 1.5, 2, 3, and 4. Anything else is rejected. Default is 2x when no factor is specified.

Usage aggregates under the topaz-labs/video-upscale key at a flat $0.06 per second of output, regardless of upscale factor or target frame rate.
