FLUX Video Upscale from @bfl_ai is now available on OpenRouter. Upscale any video in 2K or 4K, with sharper faces, cleaner textures, and finer background detail while retaining natural motion and realism.
FLUX Video Upscale offers two modes: `precise` for faster results and stronger identity retention, or `creative` for more repaired and generated detail. https://t.co/IF01hVD3HL

Context
Black Forest Labs' FLUX Video Upscale offers a choice between preserving reference details and generating more replacement detail. The developer says Precise mode is faster and better at maintaining identity, while Creative mode performs more repair but can change or replace identity. Its product article describes regeneration at resolutions up to 4K.
OpenRouter added both modes to its Video API offering. For footage in which a person's appearance must remain consistent, mode selection therefore matters beyond sharpness: a more detailed result can also contain more newly generated visual information.
