About

FLUX Video Upscale increases the resolution of a video clip. Give it up to 20 seconds of footage (mp4, at most 50MB and 2560x1440) and it returns a higher-resolution version that keeps the source aspect ratio and audio track.

Two modes

The creativity input picks how the upscaler treats your footage:

• Precise (creativity: 0) preserves the source exactly and sharpens it. Use it when identity matters: faces, products, brand assets, and footage of real people.
• Creative (creativity: 1, the default) restores and invents fine detail more aggressively. Use it on generated footage, textures, crowds, and scenery. It doesn’t preserve identity as strictly, so faces and products can drift.

A short prompt describing the clip’s content can steer creative mode toward the right kind of detail.

Scale factor

Set upscale_factor between 1.5 and 3 (default 2) to control how much bigger the output is relative to the source. Output frames are capped at about 14.4 megapixels (4K), so very large sources are upscaled by less than the requested factor.

Tips

• Start from the least compressed source you have. Compression artifacts limit how much real detail the upscaler can recover.
• Run upscaling as your final step, after editing and trimming, so you only pay for footage you keep.

Pricing

Upscaling is priced per megapixel-second of delivered output — the megapixels per output frame multiplied by the output duration in seconds. Precise mode is $0.07 per megapixel-second and creative mode is $0.10 per megapixel-second. You’re charged for delivered output only.
