Overview

Video Upscalers take a generated shot and increase its resolution, sharpen detail, and clean up artifacts — turning a 720p or 1080p clip into a polished 4K delivery.

FilmSpark offers two upscalers:

• Topaz — The industry-standard suite used in professional post-production pipelines. Multiple models tuned for different types of footage. Covered in detail below.
• Crystal — A second upscaler option available alongside Topaz. Use whichever gives you the best result for your shot.

This guide focuses on Topaz, since it's the more configurable of the two and most users will start there.

Topaz Quick Start: Which Topaz Model Should I Use?

If you're not sure, use Proteus at 2x. It's the default for a reason — fast, clean, temporally stable, and works well on most AI-generated video from Seedance, Kling, Veo, Runway, and Wan.

For premium 4K delivery where you want the best possible result and don't mind waiting longer, use a Starlight model.

Everyday Workhorses

Proteus — The default. Best all-around upscaler for most footage. Sharpens detail and reduces compression artifacts without hallucinating new content. Use this for social media cuts, client previews, and anything where you want predictable, natural-looking results.
