Giving your presentation via OBS.Ninja

As a speaker, you'd like to present your talk remotely (from home or your office). This page explains the main way the rC3 video crew uses to make that possible. With this information, and the preparation session we have invited you to, you will be able to give your presentation with decent audio and video quality.

Software being used

You will be using two pieces of software:

a web browser (Firefox, Chromium or Safari, others might work, too), for the broadcast audio and video that you're going to transmit to the control room, and

Mumble for the talkback channel between you, the video director, and the moderator (herald).

We will go through how to set up both Mumble and the website that collects the video from your camera and from your slides, and the audio from your microphone.

Using OBS.Ninja with your browser

We are using OBS,Ninja to collect the video from your webcam, the slides of your screen, and the audio from your microphone. OBS.Ninja runs in your browser, so you don't need to install any additional software.

OBS.Ninja works best in Chromium or Chrome. It can also be used with Firefox and Safari.

Shortly before your talk, you will receive two URLs by email that start OBS.Ninja on your computer. You might also get an access password together with these links.

Open each URL in a separate browser window or tab. This is necessary for the video and audio on one hand, and the screen sharing on the other. When prompted, please enter the password.

When you open each URL, a selection screen will allow you to either share your camera or your desktop. For the first URL, please select your camera, for the second, select the screen sharing option.

In both cases, your browser will ask whether you want to allow access to your camera, your microphone, and to your desktop.

If you have more than one camera, you can select which one to use.

For the screen sharing, you can choose to share (one of) your monitor(s), or individual windows. Sharing your screen is easier, but you need to make sure to close windows that you don't want to show during the talk. If you are sharing a window, make sure it is the right one for your presentation program, especially when you enter presentation mode. Usually, the presentation software will open a new window full-screen, and you might not be able to easily select that window in the screen sharing options.

Sharing your screen on a Mac

If you're sharing your screen through your browser for the first time, your Mac will ask your to go to the System Settings and allow your browser access to your screen. You will need to restart your browser for this permission to work. Make sure you have set this up at least one, preferably during the tech setup and rehearsal session.
