How Video Upscaling Works
Upload Your Clip
Drop an MP4 file up to 50 MB and 30 seconds. The tool reads the duration instantly to calculate your credit cost before you commit.
Choose Upscale Factor
Select 2× for a solid resolution bump at lower cost, or 4× for maximum detail recovery up to 4K. The price per second adjusts automatically.
Submit & Pay with Credits
Credits are deducted when you submit. The job enters an async queue — you can close the tab and come back later without losing your task.

Credit-Based, No Subscription
Pay only for what you upscale. Credits start at $3 for 600 and carry over. Failed jobs refund automatically — you are never charged for errors.
