When doing a webinar session being able to play a video would help present ideas better. As a speaker, EventX also made that available for you:
Once you enter backstage, you will find the share screen function at the bottom of the screen. Clicking that would give you an option to "Share screen" or "Share PDF"
Choose Share Screen.
3 ways to play a video using a Share screen:
Share the entire screen.
When you choose to share the entire screen you will be given a mirror image of everything you have on your screen.
2. Share a Window
Choosing this option allows you to share only a specific window available on your browser or videos which are currently open.
3. Share a Chrome Tab
This option allows you to share a specific tab from your chrome browser on PC / Mac.
Note: When using this function, always remember to check Share Tab Audio at the bottom left.
When video sharing has been done, just click on Stop Sharing.
Reminder about enabling screen sharing for your browser:
For Mac OS, please follow the steps below.
1) Open System Preferences by clicking the Apple Icon and selecting System Preferences.
2) Click the Security and Privacy icon.
3) On the left, scroll down and click Screen Recording.
4) Click the checkbox next to the browser you're using - either Chrome or Firefox should be in the list. Note, you may have to click to lock in the lower-left in order to check the box.
5) When prompted, click Quit Now. The change will not take effect and you will not be able to share your screen until you quit and restart your browser.
