Topaz Astra 2 - Unifically

Topaz’s creative video upscaler. It adds new, believable detail rather than only restoring what was there, and you can steer the look with a prompt.

Model

topaz-labs/astra-2

When to use

AI-generated video that needs a premium, high-detail finish.
Stylised content where you want to direct the look with a prompt.
Hero shots and showcase clips where the richest possible detail is worth the price.

Pick something else when:

You need a faithful restoration of real footage: use Starlight. Astra may invent detail.
You are processing large volumes: Starlight Fast 2 costs a fraction of Astra.

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
`prompt`	string	No	-	Optional description of the desired look (max 1024 characters)
`creativity`	number	No	`0`	`0` to `1`. `0` stays faithful to the source, `1` is most inventive
`realism`	number	No	`0`	`0` to `1`. Pushes the result towards photorealism
`sharp`	number	No	`0.5`	`0` to `1`. Output sharpness
`nsfw_check`	boolean	No	`true`	Check uploaded media inputs for NSFW content
