Webinars

Full HD

Run every webinar in Full HD

Every webinar in TwentyThree runs in crisp HD by default with Full HD 1080p available with a single click. Slides and played-in video run at native quality straight from our servers, so your audience sees sharp video whatever the presenter's connection. Every recording is kept in Full HD too, ready to replay on any device.

Webinar Full HD

Upgrade to a Full HD webinar in a click

Just toggle on Full HD 1080p at 3000 to 5000 kbps and the lift in quality is immediate. All you need is a camera that outputs 1080p and a little more CPU and bandwidth from hosts and speakers.

Keep webinar video quality high for slides and played-in video

Add your slides and TwentyThree videos to the WebinarTray – TwentyThree Webinars’ production plan tool – and they stream straight from our servers to every viewer. Video runs at its native resolution in Full HD at 30fps, and slides stay crisp when you upload them as PDF.

Webinar full hd gearmode 4k

Go studio-grade in up to 4K with GearMode

GearMode takes an RTMP feed from your hardware or software encoder for HD video streaming in up to 4K, with full control over bitrate, keyframes and codec. Built for teams with a real studio and AV desk, it sits at the top of the quality range. See the switcher and multi-presenter setup on live webinar production.

Webinar full hd sharpest replay every device

Serve the sharpest replay to every device

The moment a webinar ends, TwentyThree transcodes the recording into low, standard, HD and Full HD, and the player serves the sharpest version each viewer's device and connection can take. On-demand Full HD runs at 1920x1080 and 5000 kbps, so the quality you captured live carries into every replay, on mobile and desktop. See the full on-demand webinar replay experience, or download the raw HD footage from every speaker with RawMode.
