Webinar rooms

One attendee on a phone hears nothing while everybody else is fine. Nine times out of ten the phone is on silent, and the fix takes them five seconds.

Switch away from the room and the audience sees you in steps while your voice stays perfect. That is browser throttling, not your connection, and only one thing fixes it.

There is no button called Cursor. While you share your screen your own cursor already travels with it, and on slides the pointer lives in drawing mode.

Company firewalls block the UDP that WebRTC needs, so the room moves your stream to TCP port 443 by itself. What is automatic, and when the plugin helps.

Chat settings in the webinar room let you switch attendee chat off, pre-moderate messages, hide links, clear the chat and block or unblock a participant.

Frozen video and attendees who keep dropping out of the room almost always come down to the connection, so measure it before you change anything in the room.

Any moderator can put an attendee on air with the green megaphone icon. What the attendee sees, how they ask for the floor themselves, and how the turn ends.

Full-screen mode makes what you are sharing fill every viewer's window. How to switch it on from Room settings, what attendees see and how to switch it off.

Opera's built-in VPN can block your webcam and screen sharing in a webinar. Two fixes here, a WebRTC setting in Opera and a VPN bypass rule for the DTS plugin.

Show a whole monitor or one window to your audience. Download the plugin from the Screen tab, allow screen recording on macOS, then pick what to share.

Everything a presenter does in the webinar room, from the Speak button and materials to recording, polls, chat moderation, screen sharing and extra seats.

Play a YouTube live stream in the webinar room from the Media tab of the Show window, plus what stops a stream from playing for some of your audience.

How to join a webinar from the link you were sent, what you can do once you are inside the room, and how to fix problems with sound, video and the chat.

Attendees never create an account. They open your link and walk in. A room asks for a name only, a scheduled webinar adds an email, and you choose the rest.

Uploaded video is re-encoded to at most 128 kbit/s audio for the live stream, then processed again for the recording. How to restore the original track.

Fix the microphone and the room first, then the line. Where the sound controls live, what the DTS plugin adds, and how to check it all before you go on air.

Delay here is dynamic, always pulling back to the minimum. Presenters sit 100 to 600 ms apart, and the audience carries a deliberate smoothing buffer on top.

A sleeping tab can drop your webinar connection, and the room is not on the domain you would expect. Which addresses to keep awake, and how, in each browser.

Three settings on the Record tab shape the recording. What each mode captures, which corner the webcam or camera takes, and the pairing that wastes the frame.

The camera is not one size. It has a width setting and six positions, so what each needs in pixels, why two resolutions cover them, and how to improve yours.

Talk between presenters lags because every stream goes through our servers. Where the milliseconds go, why everyone waits for the slowest link, and what helps.

Click Speak, then let your browser use the camera and microphone. What the prompt looks like in seven browsers, and how to clear a block you set earlier.

How much upload and download speed a webinar needs, presenter by presenter, where to measure your own connection and what to do when the line is too slow.

Low Power Mode throttles a Mac or iPhone mid-webinar, and the picture goes first. Where it lives, what it costs, and the battery setting that is a red herring.

If a provider, a country or an office network blocks the platform, swap the domain in your room link for one of our mirrors and everyone gets back in.

Inside the room you get background blur. macOS can replace the background outright, and this is how to tell whether your Mac can do it and how to switch it on.

Six places for the presenter's camera in the live webinar room, two beside the workspace and four in a corner of it. Where the webcam position setting lives.

Screen sharing runs through our own plugin rather than the browser. Why that is, covering encryption, packet loss, picture quality and access control.

A webinar room is the virtual space where your event runs. It opens automatically with every webinar you create and works in the browser on any device.

When WebRTC or UDP is blocked, switch the room to the downloadable DTS plugin. How to activate it, install it on Windows and macOS, and fix repeat prompts.

Set up an OBS Studio stream into your webinar room over RTMP, from the settings that unlock it to the Server and Stream Key fields, sources and going live.
