Quick Answer

Why use a broadcast platform instead of Zoom for presentations?

Zoom optimizes for bi-directional voice conversations, heavily compressing video to 720p at low bitrates and introducing attendee interruption risks. ClosedDoors is built for unidirectional broadcasts, supporting 4K at 60fps via OBS or vMix with device-bound attendee security.

Why video conferencing tools fail for major presentations

Webinar software is designed for two-way discussions, introducing compromises for keynote speakers and producers.

Breach Vector 01

Aggressive video and audio compression

Zoom drops video streams to 720p or lower with variable frame rates to minimize latency. Slides with fine typography and motion graphics blur on large monitors.

Breach Vector 02

Accidental unmuting and room disruption

Attendee microphones and webcams remain an ongoing risk during high-stakes announcements. Moderation requires continuous vigilance over the participant grid.

Breach Vector 03

Mandatory desktop app installations

Guests often encounter browser redirects asking them to install or update local client software, causing late arrivals and authentication friction.
