Cover image for A client commissioned us to
A client commissioned us to build a live video production studio from scratch, running entirely in the browser with no specialised equipment needed. The result is a SaaS application with multi-camera compositing, WebRTC ingestion, and RTMP output to Twitch, YouTube, and Facebook. The application included multi-camera compositing, real-time social media comments overlay, customizable backgrounds and overlays, and a layout manager for arranging the positioning of video sources and content on the fly. In this project I handled the brand identity, the complete interface design, and the interface development with Nuxt 3. The biggest challenge was organising a feature-rich application into an interface that felt intuitive for non-experts.
