# FLUX Video Upscale: 2K and 4K

By Steven Van · 2026-08-20

FLUX Upscale regenerates existing video at up to native 4K, and it is offered both as a standalone FLUX Tool and as an API endpoint.

Any video can now be regenerated at a higher resolution, up to native 4K, with FLUX Upscale from [Black Forest Labs](<https://creatorstoolbox.com/tools/black-forest-labs>). It is available as its own FLUX Tool and as an endpoint, and the [announcement](<https://bfl.ai/blog>) lists 2K and 4K output.
