Black Forest Labs launches FLUX Video Upscale with native 4K regeneration
On August 20, Black Forest Labs released FLUX Video Upscale, a standalone FLUX Tool and API endpoint that regenerates videos from 480p and above up to native 4K. It went live on the fal platform the next day, letting users upscale videos to 1080p, 2K, or 4K.
Confirmed
- The company describes it as a native upscaling solution for FLUX 3 Video: it natively understands FLUX 3 outputs, fixes blur that generic upscalers struggle with, and repairs generation artifacts
- Key improvements include sharper faces, cleaner textures, and finer background detail, while preserving FLUX 3's style diversity, natural motion, and realism
- The fal platform offers two modes: Precise, which faithfully preserves faces and product details, and Creative, which reconstructs details and supports prompt-based control
- @robrombach relayed claims that the tool is reportedly fast
Why it matters
- FLUX Video Upscale is embedded directly in the official toolchain and API and is natively tailored to BFL's own model outputs; commentators argue that third-party generic video upscalers will face further pressure
