ByteDance 4K AI video upscaler

ByteDance 4K upscales a finished video to 1080p or 4K. There is no prompt. Credits are charged in 5 second blocks. See the credit table below.

Best for

ByteDance 4K is a video upscaler. You send a finished clip and choose 1080p Full HD or 4K Ultra HD. There is no prompt, no style preset, and no reference image. The job is resolution, temporal stability, and noise, not a new scene.

Where it fits

Use it after a generation you already like, or on footage that is soft at the size you need to deliver. If you want to change the look with words, use Topaz Astra 2 or Kling video-to-video instead. If you want a simple 2x or 4x scale, Real-ESRGAN is the other video upscale option.

How to use it

Open the video enhancer and choose ByteDance 4K, or open the video upscaler, which selects this model. Add the clip, pick 1080p or 4K, and run it. The 4K target costs more per 5 second block than 1080p. The table lists those 5 second prices on the Free plan.

Controls and pricing

Longer clips are more blocks, and the calculation caps the billed duration at 60 seconds. This is not an image upscaler. AuraSR, Clarity, and SUPIR are for stills and use a different credit table.

Good to know

Upscale the cut you will deliver, not every experiment. A 4K block costs more than a 1080p block, and a minute of 4K is twelve of those blocks at the cap. If you are still changing the edit, stay at 1080p until the picture is locked.

Also worth knowing

ByteDance is the right finish when the edit is locked and the delivery spec is 1080p or 4K. It will not restyle the grade. If the color or the world still needs to change, do that with Topaz or Kling video-to-video before you pay for the larger file. A locked edit is the only clip worth the 4K block price.
