The hardware Acceleration: 'prefer-hardware' flag tells the browser to delegate to the GPU encoder first. On Chrome 94+ and Edge, this is widely supported across Windows, macOS, and Android.
WebGL — Chroma Key Without a Server
Green screen removal is computationally expensive if done naively. AetherCut handles it via a WebGL fragment shader that runs on the GPU — no frame-by-frame CPU pass, no upload to an AI service.
The shader samples each pixel's hue and saturation, compares it against the chroma key target color, and writes a transparency mask in real time. This runs at frame rate during preview.
