Webex Events Streaming is a combination broadcasting studio and player that runs on Restream. This article covers how to enable Webex Events Streaming and successfully produce a professional quality live stream. To learn more about Webex Events Streaming and if it is right for your event, check out our Introduction to Webex Events Streaming article.

Enable Webex Events Streaming

⭐️ Keep in mind, Webex Events Streaming is an additional cost add-on feature. Reach out to your Webex Events contact for pricing.

First, add a Live Stream feature or enable Live Stream for a session, and select Webex Events Streaming by Restream from the provider drop-down in the Live Stream section.

The first time you add Webex Events Streaming for a Live Stream feature or Agenda session in your event, a modal appears with a prompt to confirm using a Webex Events Streaming credit. A single credit is good for an entire event, whether you have one live stream or a hundred. Click Activate to continue.

Screenshot of the Activate Webex Events Streaming pop-up.

⭐️ Keep in mind, if the button in the bottom right corner of the modal says Purchase instead of Activate, you can click Manage Teams to see the credits assigned to each team you're a part of. If necessary, use this process to transfer credits between teams. You can also click Purchase to start a chat with our support team and get credits added.

Now, click Save.

Invite Speakers

Inviting your speakers couldn't be easier! You simply share a link with them that they use to join the studio before your live stream.

Edit the Live Stream feature or Agenda session you made previously. The Invite Speakers link will now be available. Copy the link, and send it to your speakers or presenters joining the stream. We highly recommend sharing the Webex Events Streaming Speaker Instructions article with them as well.

⭐️ Keep in mind, if you're using Webex Events Closed Captions & Translations, the Invite Speakers URL changes any time you enable or disable closed captions, or when you change the provider to/from Webex Events Closed Captions & Translations. Make sure to send speakers the most up-to-date link after making changes. For more info, check out Webex Events Closed Captions & Translations.

⭐️ Keep in mind, you can have 10 people in the stream at a time. Anyone with the link can join and no login of any kind is required. If you have more than 10 people joining your stream, you may choose to have a "waiting room" in another meeting tool, or use another streaming studio with the Webex Events RTMP Player.

Launch the Studio

In the same Edit modal where you copied the Speaker link, click Launch Studio to open the live streaming studio in a new tab. This is where the behind-the-scenes magic happens! Before you're fully in the studio, use the "Ready to join" screen to check your audio, video, and green screen settings, and enter your name. Click Join Stream when you're ready.

⭐️ Keep in mind, for the best results, we recommend using the Restream studio in Google Chrome.

Screenshot of the Ready to join modal.

⭐️ Keep in mind, the Launch Studio button is only for you as the admin/moderator, and you shouldn't share it with other speakers. The Launch Studio link changes every 24 hours to keep your studio secure. Give speakers the link we mentioned in the section above, or have them log into the Webex Events Platform and click the Launch Studio button if you want them to be able to control the views, banners, etc.! 👆

In the Studio, start by clicking the Settings (⚙️) icon at the bottom of the screen to adjust your Video input, Audio input, and Audio output devices. There are also some additional stream settings under General, and you can set a solid or virtual background on the Virtual Background tab.

Setting up your stream

There are many areas to consider when setting up your stream. Be sure to give yourself and your speakers plenty of time to play around and get familiar with the studio before you go live. For a breakdown of each section, read on! 📖


To the left of the screen preview, each speaker is listed. Make sure you click the toggle to add yourself and any other speakers who will speak during the first part of your stream.

Screenshot of the Restream studio. A speaker's toggle is indicated.

You can add and remove speakers throughout the stream and adjust their volume or mute them if needed. You must add a speaker to the stream for their audio and video to work.

You can click the 3 dots above your speaker card to change your avatar and edit your name. If you click the 3 dots next to someone else's speaker card, you can edit their name, or remove them from the studio.

Screenshot of the 3 dot menu expanded both for the host, and for a speaker.


Above the toolbar icons, you can change the view layout to highlight what you want users to focus on. Again, you can change this during your stream as well. Views you can choose from include:

  1. Contain - This view shows each presenter and source with some space between them. This is great for when you want to show a background with sponsor content, highlight chats, or show captions.

  2. Cover - This view is perfect for when the speakers are the only focus and you don't need to show background content or non-person sources.

  3. Half Screen (not pictured above) - This is a combination of the Contain and Cover layouts. The speaker or source on the left takes up the half side of the stream, and anyone else shows up on the left in a smaller frame.

  4. Picture-in-Picture - This view and the following two are great for when speakers are sharing content and discussing it, whether it's their screen, a video, an image, or something else! The content they're discussing can take center stage while the speakers appear in small frames either below the content, or to the side.

  5. Cinema - See Picture-in-Picture

  6. Thumbnails - See Picture-in-Picture

Studio Toolbar

Screenshot of the Restream studio toolbar.

The toolbar at the bottom of the screen gives you the following functions from left to right:

  • Mute - Mute or unmute your audio.

  • Disable/Enable camera - Start and stop your camera from appearing on the stream.

  • Share screen - Choose to share your whole screen, a window, or a browser tab and any audio playing. If you choose to share your whole screen, sharing audio may not be an option.

  • Invite guests - Invite other speakers to your stream to present.

  • Add source - Add a presentation, video, or background music to your stream. Captions, logos, and overlays can appear on top of any of these sources!

  • Settings - Adjust Video and Audio input, and set advanced Audio preferences.

    ⭐️ Keep in mind, Live Stream Quality and Video resolution settings won't affect the stream.

Share screen

Screen sharing is an awesome way to present a program or website or show a slideshow. Both you and your guest speakers can share anything on your screen.

Screenshot of the

Click the Share screen button below the view selection. A modal appears with three options:

  • Your Entire Screen — Shares your entire desktop screen.

  • Application Window — This lets you choose one application at a time and is great for sharing a PowerPoint or keynote.

  • Chrome Tab — This lets you share any file from your computer in a Chrome Tab. Open a new tab and drag the file into Chrome from your computer desktop or folder. Your cursor displays a little plus sign if the action is successful. This is the best way to share audio. To share audio from your screen, you must click the Share system/tab audio checkbox.

Now, click Share, and your screen appears with your speakers and sources on the left side of the studio. Use the layout buttons under the screen to change how the screen appears alongside you and your speakers.

Add source

The Add Source modal has six options:

  • Extra camera

  • Presentations

  • Video storage

  • Local video

  • RTMP Source

  • Background music

To add a source of any type, simply click the Add Source (+) button, select a source, and then complete the necessary steps. When you add a source to the studio, it appears with your speakers and other sources on the left side of the studio, and you can control each one in different ways.

Screenshot of the Add to your stream modal.

Now, let's take a look at how each one works:

  • Extra Camera - Select a secondary camera connected to your computer. This could be useful for showing yourself from multiple angles, or showing someone else in the room with you.

    ⭐️ Keep in mind, adding an extra camera doesn't add a secondary audio input.

  • Presentations - Click Upload to add up to 24 PDF, key, pptx, or docx files from your computer, or click Drive to select a file from your Google Drive account. Once the presentation uploads, click on it to add it to the studio. Use the toggle in the upper right corner of the source panel to start showing the presentation, and use the arrows at the bottom of the source panel to control the slides.

    Screenshot showing the live toggle and slide controls on the source panel for a presentation.

    ⭐️ Keep in mind, Restream doesn't support video, audio, or animations in presentations, and only the first 500 images in a presentation will be loaded.

    Your studio guests can also add presentations and control the slides. Only you can click the toggle to add presentations into the live stream, however.

  • Video storage - Click Upload Videos and select a file from your computer, or click the Descript, Google Drive, or Dropbox buttons, and paste a public link to a video hosted on one of those sites. Whichever of these options you choose, the file will take some time to import and process, so make sure you add videos well before the live stream starts.

  • Local video - Click Local video and select a video file stored on your computer. Once the file fully processes, select it to add it to the studio. Locate the video in your list of speakers and other sources on the left, and click the toggle to add it to the live stream and begin playing it.

    When playing video from either Video storage or Local video sources, use the Play/Pause button and volume slider to control your video. Local video and Video storage also support video looping!

    Screenshot of the source panel. A Local video and Video storage video have been added.
  • RTMP Source

    This option lets you bring a single RTMP stream from a 3rd-party tool like Webex or OBS into the studio so you can take advantage of all the layout and branding opportunities Restream offers. This also lets you stream from a combination of on-site and off-site locations using the Restream studio.

    ⚠️ Caution! This is an advanced use case that requires you to configure and operate an additional third-party tool. Read Restream's RTMP Source guide for setup instructions and required encoding settings.

    After you start streaming from your third-party tool, the stream appears in the left panel, just like the Cloud Storage video pictured above. Click the toggle to add the RTMP Source to the live stream, and use the slider to control the volume.

    ⭐️ Keep in mind, RTMP Source shouldn't be confused with the Webex Events RTMP Player.

  • Background music - Click Background music and choose from Restream's list of music tracks. After you click Select next to one of the options, the track is added to your stream with your speakers and other sources. Simply click the toggle to add it to the live stream.

Screenshot of the Background music modal.

Before we continue, let's talk about the benefits of each type of pre-recorded video you can use in the Restream studio. Including Video Clips, which we'll talk about more later, Restream provides three different options for sharing pre-recorded video in your stream. Here's a breakdown of the benefits and limitations of each:

Video Clips

Video storage

Local video

Max length

1 hour

2 hours


Max size




Total allowed

(all studios)








Volume control








Video Loop




⭐️ Keep in mind, when sharing Local video, the speed of your internet may affect the quality of the video in the stream. We recommend using Video storage or Video clips for the best results. Follow Restream's video and audio guidelines for the best recording and encoding settings.


If chat is enabled on your Webex Events Stream (on the session or Live Stream feature), then any chats that come in from users appear in the Chat tab. You can click on a message to have it appear on screen during your live stream.

Animated GIF showing a user clicking

⭐️ Keep in mind, you'll only see the comments that occurred after you joined the studio.


Add a Lower Third type caption to the stream to show a static banner with additional context, quotes, or calls-to-action.

Use a Ticker for an eye-catching banner than moves across the bottom of the screen. You can create these pre-stream and simply select them at the opportune time, or create them on the fly during the stream.

Animated GIF showing a user adding a Ticker to the stream.


This tab has lots of options to brand your stream and make it your own. When you upload graphics assets to one studio in your event, those assets are available in every other studio! So if you want to use the same custom countdown reel, sponsor banners, or overlays in every live stream in your event, you still only have to upload once.

Screenshot of the lower portion of the Graphics tab.

The Theme lets you choose how Captions and Chat comments appear on the stream. Primary color determines the color of the Theme. There are toggles to hide the Default graphics, non-video participants, and participant names, and a toggle to choose whether or not to Automatically share screens when speakers select a screen to share.

You can also upload custom Logos, Overlays, Video clips, and Backgrounds.

If you click on a Logo, it appears in the top-right corner of your stream. Logos should be 512x512px JPG or PNG files.

Overlays let you add up to 50 custom frames or info banners in your live stream, or you can use overlays as transitional graphics. Overlays should be 1920x1080px JPG or PNG files.

The Video Clips feature lets you share up to 200 videos of 2 GB or less AND 1 hour or less. Acceptable formats are MP4, FLV, MOV, TS. WEBM, and GIF.

⭐️ Keep in mind, video clips MUST be 16:9 ratio and no less than 720p. Processing/upload time will vary depending on internet connection. Uploads could take up to 2x the video duration (example: a 1 hour video may take up to 2 hours to upload and process).

A custom Background is a great way to make sure your stream is on-brand! Backgrounds should be 1920x1080px JPG or PNG files.


If you have a lot of custom content to upload, and not all assets will be used in every stream, it can get a little hectic trying to find the right assets during showtime. That's why we've partnered with Restream to bring you Brand folders so that any assets you upload to one Brand won't appear in the others.

Simply click the Brand button in the top right corner of the screen to make a new Brand or switch between existing ones.

Animated GIF showing a user clicking the Brand dropdown in the Restream studio.

You can add up to 10 Brands, and Captions and everything on the Graphics tab — Theme, Primary Color, Logos, etc. — are unique to each brand. Just like before, all assets in one studio are shared with every other studio in your event.

Private Chat

If you need to send messages to your fellow presenters, you can use the Private Chat. These messages only appear to the host and guest presenters in Restream. These chats remain after the stream has ended.

Go Live

When you're ready to stream to the Webex Events Platform, click Go Live in the upper-right corner. You can continue to add or remove speakers from the stream, change graphics, views, and more.

😎 Pro Tips!

  • Don't forget to download your stream recordings and host them online so attendees can watch them later!

  • Check out our Webex Events Streaming FAQs article for even more great tips and tricks.

  • Screen sharing works best when you have two monitors – two monitors make it easy to click from slide to slide while you’re still controlling the live stream on the other monitor.

  • Webex Events Closed Captions & Translations uses machine learning to provide closed captioning and written translations at no additional cost! We also support human closed captioning and audio captioning through third-party caption vendors.

  • If you’re serious about streaming (and we hope you are!), we recommend investing in a high quality mic and webcam. A pair of headphones is also a good idea – this reduces the potential for echo if you are bringing on guests. We're big fans of the Yeti Microphone and C920 Webcam.

  • Streaming requires a lot of data, but your current ISP or 4G provider should work fine. We recommend that you hardwire (ethernet) to your router. WiFi works, but not as well. You’ll want an upload speed of at least 10 Mbps. You can test your speed here. Make sure you’re looking at upload speed, not download.
