FLUX Video Upscale: 2K and 4K for Video
Create videos in 2K or 4K with sharper faces, cleaner textures, and finer background detail.
FLUX 3 Video’s native upscaling is designed to retain FLUX 3’s style diversity, natural motion, and realism at higher resolutions, with faster results than 3rd party upscalers. You can also use it to upscale any video.

Native upscaling drops a separate third-party pass from video pipelines while preserving motion and style, and it accepts video you generated elsewhere.
