Black Forest Labs upgrades FLUX Video Upscale: video upscaling up to 4K

Black Forest Labs has updated its FLUX Video Upscale video upscaler, which enlarges a video 1.5× to 3× up to 1080p, 2K or 4K, with a precise mode (faithful to the source) and a creative mode (adds detail), keeping the audio. BFL claims it costs less than Topaz Astra 2 and runs twice as fast: this is BFL's claim, with no published comparison. Official prices (BFL docs): billed per megapixel-second of output, $0.035 precise and $0.05 creative, about $0.07/s and $0.10/s at 1080p, $0.28/s and $0.40/s at 4K. Source video: 20 s and 50 MB max.
