About AI Video Upscaler
AI Video Upscaler prioritizes spatial resolution and detail recovery while keeping color and denoise adjustments conservative.
Common use cases
Archive viewing copies
Prepare an enlarged viewing copy while keeping the original source video unchanged.
Pre-publishing enhancement
Upscale a short clip before final web delivery when extra resolution is useful.
How it works
1
The source video is decoded into timed frames in the browser.
2
The Real-ESRGAN-based pipeline applies AI enhancement to selected keyframes and combines that result with source-cadence processing.
3
The enlarged frames are encoded and muxed into a new video output.
Privacy & file handling
Video upscaling stays on the device
The supported AI upscaling workflow processes source frames locally in the browser instead of uploading the original clip to Zavilo.
Limitations and important notes
- Upscaling creates more pixels but cannot guarantee recovery of real detail that was never captured.
- Long, high-resolution or high-frame-rate videos can take substantial processing time and memory.
- Browser WebGPU support and hardware capabilities strongly affect performance.
