# Topaz Upscale Video Generative

**Node type:** `video:topaz_upscale_video_generative`  
**Category:** `video`

## Description

Topaz Starlight generative (diffusion) video upscaling. Starlight Precise 2.6 adds realism to AI-generated video, with a softness control from 1 (sharpest) to 5 (softest). Up to 4x. Billed per output second at the resolution tier of the output (up to 1080p, or 4K); the listed price is the 4K ceiling.

## Pricing

- **Cost:** ~41 credits per seconds
- **Per-second rate:** The figure is the rate at a 5-second reference run. Our margin is progressive and steepest on the smallest runs, so a clip shorter than that can cost more per second, and a model priced with a flat multiplier is exact at every length. The charge is always computed from the real duration.
