Keynote / PowerPoint in mimoLive Stream

This is likely in the docs, but what is the best approach to cutting back and forth into to a Keynote during a live stream?

  1. Run your Keynote in the background
  2. Import the Keynote source as a “Window Capture” source
  3. Add the source to your layer stack
  4. Turn it on and off as needed

You’ll need to switch to the Keynote window to advance the slides, or use and iPhone or iPad as a “Keynote Remote”, which would allow you to keep MimoLive frontmost.

Like with YouTube videos I found that using Keynote/PowerPoint on a second computer and grabbing the HDMI output works best. I recommend the Magewell Pro Convert for that if you want to capture a presentation someone is doing live.

This 2nd machine strategy is our approach, too. Sometimes we use three laptops … as follow

  • Laptop up on the podium for the presenter with Keynote running (this gives them a visual of what is up on the screen without having to turn to look at the screen)

  • Laptop HDMI --> ethernet extender at projector --> to 2nd HDMI extender that goes to the Mimolive production station. (Our HDMI extenders have an input and a loop out so they function as splitters - that’s how we drive the projector and the second extender simultaneously)

  • MimoLive production station (the second HDMI goes into a Magewell which plugs into USB)

  • The third laptop is at the MimoLive production station and uses Apple Remote Desktop to control the podium laptop. That way we can change presentations and/or take control if the presenter needs help. (we often produce scientific meetings with a new presenter every 10-15 minutes.)

$49 OREI 164-Feet HDMI 1080p Extender Over Single CAT5/CAT6, Loop Out Option, with IR

The Magewell is an excellent capture device … you can use less expensive HDMI -> USB frame grabbers. For static and animated screens you will be fine with just about anything, however, if there is embedded video or audio make sure you do a test run with the less expensive hardware first.

Dean, Thanks for sharing!

I did my first livestream with Keynote yesterday. Of course, I got the presentation on screen with less than 2 minutes to spare. It worked, but not well, running Keynote on the same Mac as mimoLive. The problem is Keynote seizes the screen, even when operating with two monitors.

I’ll definitely be running Keynote on a separate computer in the future. Will produce a far superior show, and also allow me to do picture in a picture, because online, it is really necessary to put your live presenter on top of whatever Keynote or Powerpoint slide you are showing. This became especially evident when my presenter went off-topic in the presentation, leaving a slide on screen for a prolonged period. Trying to run Keynote on the same Mac with mimoLive makes it impossible to switch back and forth from live presenter to the slide deck because Keynote has control of the Mac screen unless you escape the program, which creates another set of problems when it is time to resume the presentation.

Hi Danny, happy new year and thanks for the report. This is a problem where we do not have a good solution. It really is best to run the presentation on a separate computer or iPad.

Thanks for the reply. Since posting, I’ve reconsidered my entire plan of attack, and it is clear I tried something that was ill conceived. The good thing that comes out of this is I realize now I have all the pieces on hand and available to dedicate and interface a Mac Mini into my system. I’m confident all future attempts at incorporating either Keynote or Powerpoint into my live streams will be rock solid and free of stress – exactly as you suggest, by using a dedicated computer to run the presentations!

how does the USB source get brought into MIMO? What layer do you use?

Can you describe more specifically what you want to achieve?

You can use any Source with any Layer (if it takes a source), so it depends on what you want to do with the source.
