Google's video model can now continue an existing clip in ten-second steps up to forty seconds total, reading up to ten seconds of prior footage instead of only the final second. A 360p draft mode runs up to 60 percent faster at a third of the cost, and finished work upscales to 1080p or 4K.

Black Forest Labs released FLUX Upscale on August 20 as a standalone tool and endpoint that regenerates video up to 4K. It runs in two modes: Precise at $0.07 per megapixel-second and Creative at $0.10. The billing detail matters more than either rate, because the charge is calculated on the output alone, so the upscale factor you pick is what sets the bill.

Three ways to buy generated video in August 2026: per second through an API, as monthly credits with every model in one place, or as credits tuned for iteration. The same ten-second 1080p clip costs anywhere from $0.80 to $7.00 depending on which door you walk through.
