The problem

After Effects and Premiere are expensive and complicated. Cloud services charge per minute and upload your footage to their servers. Chroma key requires a green screen and controlled lighting.

The NSS solution

NSS Video Background Remover processes your clips frame by frame in your browser. No green screen. No upload. Export WebM with true alpha transparency or MP4 with a composited background.
