Enabling HD video for Zoom Webinars

Zoom Webinars can send and receive HD video, allowing you to broadcast your event to attendees in high resolution.

When enabled for Zoom Webinars, 720p video quality is used for the active speaker video in a webinar, and only Zoom Events or Zoom Sessions accounts have the option for 1080p video in their webinars.

H.323/SIP devices can send and receive video up to 1080p. However, for 1080p or higher, it must be enabled by Zoom Support, as well enabled on the provisioned device, or have the device join using a specific dialing string.

Zoom Meetings can also use HD video in group meetings, with 1080p video being available to Business and Enterprise accounts.
