Topaz Starlight HQ - Unifically

Generative enhancement tuned for clean, modern video. Instead of repairing damage, it adds high-quality detail to footage that is already decent, from 480p up to 4K sources.

Model

topaz-labs/starlight-hq

When to use

Your footage is already good (modern camera, clean phone video, sharp AI video) and you want it crisper or in 4K.
Upscaling 1080p or 1440p content to native-looking 4K.

Pick something else when:

The footage is old, blurry, noisy, or compressed: use Starlight Fast 2 or Precise 2.6. HQ is not a repair model.

Billed per second of the input video, counted at 30 fps: a 60 fps upload counts double and a 24 fps upload 0.8x, because every source frame is processed. Output fps does not change the price. 1440p and 4k use the 4K rate.

Parameters

Parameter	Type	Required	Default	Description
`video_url`	string	Yes	-	Publicly-accessible URL of the source video
`resolution`	string	No	`1080p`	Output resolution (long edge). One of `720p`, `1080p`, `1440p`, `4k`. The short edge follows the source aspect ratio. The source must be smaller than this
`fps`	number	No	`30`	Output frame rate. One of `24`, `25`, `30`, `50`, `60`. Does not change the price
`nsfw_check`	boolean	No	`true`	Check uploaded media inputs for NSFW content
