How to get the best out of Gen-4 Upscale (4K)
Gen-4 Upscale (4K) on Pixio is Runway’s 4K video upscale. You input a clip (e.g. 720p or 1080p) and the model increases resolution to 4K while preserving detail and reducing artifacts better than simple interpolation. Use it when you have a final cut and need delivery-ready 4K for broadcast, cinema, or high-res display.

Gen-4 Upscale (4K) on Pixio is Runway’s 4K video upscale. You input a clip (e.g. 720p or 1080p) and the model increases resolution to 4K while preserving detail and reducing artifacts better than simple interpolation. Use it when you have a final cut and need delivery-ready 4K for broadcast, cinema, or high-res display.
Use this when
- You have finished video (e.g. from Gen-4, Seedance, Kling, or any source) and need 4K output for delivery.
- You want AI upscaling that preserves sharpness and detail rather than basic resize or interpolation.
- You’re finishing a Runway pipeline: generate with Gen-4 or Aleph, then upscale to 4K for client delivery.
- Your deliverable is broadcast, cinema, or high-res display and 4K is required.

Why 4K upscale after generation
Most video models output at 720p or 1080p. For 4K delivery you either need a native 4K model (rare) or an upscale step. Gen-4 Upscale is tuned to retain detail and reduce artifacts—better than a simple resize—so your final export is suitable for high-res use. Run it as the last step after you’re happy with the edit and style.
