Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 6, Utility: 7)

Kino Transcode is a browser-based tool that converts professional camera formats like Blackmagic RAW, RED R3D, and ProRes to MP4 or ProRes MOV using WebCodecs and WebAssembly, with no installation or account required. It enables local, private transcoding with in/out trimming and maintains high bit depth for certain formats. The project is interesting for bringing complex video decoding and encoding to the web platform, leveraging modern browser APIs for a traditionally desktop-bound task.

Target audience: video editors, content creators, backend developers
