How to use PowerPoint or Keynote in WebinarJam

This article is for: Legacy WebinarJam Users (Customers who joined prior to Sept 2017)


Generally Powerpoints do not work in fullscreen mode. (attempting full screen will cause your webinar to freeze)

So we strongly recommend a suggestion from our sales page as one of the best ways to display a PowerPoint or Keynote slide presentation during your live webinar.

Pre-record the whole event as a video and, whenever you're ready to begin the presentation, simply click on the Play button and let the video do the presentation for you while you sit back and relax. Not only it will be less stressful for you, but also less risky since you can edit your video file to perfection!

However if you do want to display the presentation live, be sure to set up your presentation to play in it's own window.

Tips for Best Viewer Experience
  1. Create your Powerpoint in the 16x9 aspect ratio. It will better fill the screen.
  2. Go to setup slideshow and choose the option to play in an individual window.
  3. When you're ready to show the presentation, click play in Powerpoint, it makes the whole show run in that window and removes the thumbnail images on the left. This will give a better experience for your users.
  4. For fullscreen... no matter what size the window is that you're sharing on the webinar, screenshare will make it fully fit the video screen. So, I size my presentation window to be about 1/4 of my screen and operate it in the top right, so I can still see all of my webinar controls on the rest of my computer screen.
  5. But for the best results, skip animations (always a good idea with streaming video).
You can let other people see what’s on your computer screen by using the Screenshare app. Screenshare app icon  The screenshare app is automatically enabled during your Jam Session.  
You find it on the left side of the screen, with the other controls.  You can use it to share a slide presentation, page through a document, show a picture on your screen, or even your whole desktop** Please read the note at the bottom.  
To share your screen:  
At the top of your screen are several different icons. Click the Screenshare app icon.  (Marked #3 Below)
3) In the window that appears, choose whichever application, program or presentation you'd like to share.  In this case I shared a PowerPoint.
Please read: How do I share My Screen for more information as this screen may vary based on browsers. 
Note: Make it 1/4 of your screen for the best experience for you and your attendees.  This keeps the image from distorting and allows you to see your WebinarJam screen.
4) Click Start Screenshare. You can stop sharing your screen at any time by clicking Screenshare again.  
5) A Green strip at top may appear. Click present to everyone, or your attendees will see a black box and that’s it.
**sharing your entire desktop is not recommended because of a "fun house mirror" effect that happens when you share the image of you sharing your screen.  Instead, choose to share just the window you're using for your demonstration.


When creating your presentation, in your PowerPoint menu, go to Slide Show -> Set Up Show -> select 'Browsed by an individual (window)' then it shows the full window.
The presentation won't go full screen, but instead the presentation itself will be contained within its own window so you can simply select to screenshare-broadcast only that individual window, and thus effectively achieving the same effect as if you were full screen.
No matter what size your presentation on your desktop, when you share that window, it will expand to fit the size of the screen for attendees. So during the live event.
1> prepare before you go live by clicking play on the powerpoint presentation
2> size the window (choose about 1/4 of your desktop space)
3> use the screenshare function to share that particular screen for the attendees
Only that window is shared, and you can cover it up with other windows on your desktop without affecting the viewer experience. So while you move back and forth between your WebinarJam screen and the powerpoint, attendees will only see the powerpoint window you shared.
Remember, you'll need to make the powerpoint window the active window again to advance the slides.


As for Keynote, export your presentation to HTML and open it in a new browser window. Then open the index.html file that is created in a browser window. The animations are captured. Then follow the screenshare instructions above.

If all of this is too much for you, simply convert your presentations to pdfs. You can page through the pdf file just like a powerpoint, with far less use of your system resources.
