Input schema

The fields you can use to run this model with an API. If you don’t give a value for a field its default value will be used.

Field Type Default value Description
input_video
string
The video to upscale. Must be an mp4, at most 50MB, 20 seconds, and 2560x1440 (2K) of source footage.
upscale_factor
number
2

Min: 1.5

Max: 3

How much to scale the output relative to the source resolution. The output keeps the source aspect ratio. Output frames are capped at about 14.4 megapixels (4K), so very large sources are upscaled by less than the requested factor.
creativity
None
1
How the upscaler treats your footage. 0 (precise) preserves the source exactly and sharpens it — use it for faces, products, and real people. 1 (creative) restores and invents fine detail more aggressively — use it for generated footage, textures, and scenery, but it doesn't preserve identity as strictly.
prompt
string
Optional description of the clip's content to steer the enhanced detail. Leave empty for a neutral upscale.
safety_tolerance
integer
2

Max: 4

Moderation strictness for the prompt and the delivered frames, 0 (strictest) to 4 (most permissive).
