Enterprise recording tools (Otter.ai, Fireflies.ai, Teams Intelligent Recap) optimized for machine parsing; the human consumption problem at playback time remains structurally unsolved.
Key Takeaways
Root cause is architectural: at meeting end, audio, video, and screen share are silently merged into one MP4 and source streams discarded permanently – foreclosing personalization and layout control downstream.
Panopto is the lone exception preserving separate streams, but does not expose them for viewer-controlled switching; every other major platform (Zoom, Teams, Meet, Webex) makes the same irreversible capture-time decision.
The author built FBS-to-MP4 conversion from scratch for Fuze’s 400,000-user platform: RFB player dumped JPEGs per frame, ffmpeg concatenated at 30fps, Black Image Padding Technique handled resolution distortion.
Offline export used Xvfb + ScreenCastify + ffmpeg in a headless Linux environment, with a RabbitMQ async queue to avoid blocking UI threads on multi-hour export jobs.
Proposed category – Intelligent Replay Systems – treats a recording as independently synchronized audio/video/screen-share streams assembled dynamically at view time, with role-aware packaging (new joiner vs. senior engineer getting different cuts).
