Straight talk on speed
This runs on your CPU inside the browser tab, so it's roughly real-time: a 1-minute SD clip takes a few minutes to upscale. Best suited to clips under ~10 minutes. Upscaling happens frame-by-frame with Lanczos (the same family of algorithm pro editors use) plus an unsharp pass to restore perceived detail — then everything is packed into a universally playable MP4.
No frames are uploaded anywhere. Close the tab mid-job and nothing lingers on any server — because there isn't one.
