Video Upscaler AI enlarge clip
Upscale video with ByteDance 4K, to 1080p or 4K, or with Real-ESRGAN at 2x and 4x. Both bill in 5 second blocks. See the credit table below.
Best for
Video upscaling lives in the video enhancer, not in the image upscaler. ByteDance 4K targets 1080p or 4K and does not take a prompt. Real-ESRGAN scales a video by 2x or 4x, also without a prompt. Topaz Astra 2 can upscale too, and it can restyle, so it has its own page.
Where it fits
Use ByteDance when the delivery size is 1080p or 4K. Use Real-ESRGAN when you want a straight 2x or 4x enlarge. Neither tool invents a new performance. They enlarge the clip you provide. If the shot itself is wrong, generate it again before you upscale.
How to use it
Open the video upscaler to land on ByteDance 4K, or open the enhancer and choose the engine. Set the target, run a short portion, then run the full clip. Credits are 5 second blocks. ByteDance costs more at 4K than at 1080p. Real-ESRGAN costs more at 4x than at 2x. The table on this page and on the ByteDance page lists those prices.
Good to know
Billing counts blocks up to a 60 second cap. Do not use the AuraSR still price for a video file. Image and video upscalers are different engines.
Also worth knowing
A five second test at the target size tells you if the enlarge is clean. Faces and type are where a bad upscale shows. If those hold, run the rest of the clip. If they smear, try the other video engine before you spend a longer file.
Prompting tips
ByteDance answers a delivery spec of 1080p or 4K. Real-ESRGAN answers a 2x or 4x scale. Neither accepts a prompt, so the clip you upload is the clip you get back, only larger. Restyle first if the look still needs to change. Five seconds at the target size is the test that saves a long file. ByteDance bills more for 4K than for 1080p. Real-ESRGAN bills more for 4x than for 2x.
