Getting started with mmhmm

Hello and welcome to mmhmm! 

Thanks for being a beta tester! Because this is beta software, it'll be changing frequently. Please check for upgrades often and install them whenever they’re offered. Each update will include release notes with details on what's new.

Please report bugs to We really appreciate this! If you need help troubleshooting, just send us a note and we'll be happy to assist as quickly as we can. With your help, we plan on releasing mmhmm to the world this fall.

Here are some tips to get you started:


Look your best

This beta works great with a green screen or any solid color background. If you have one of those, the first thing you should do when you launch the app is click the Camera button on the top right, check the I have a green screen box, and tweak the Threshold slider as needed. We’ve also added a Zoom slider to the Camera so you can crop the edges if parts of your green screen keep sneaking into view.


If you don’t have a green screen, we’ve got you covered! Just leave the I have a green screen box unchecked (you can zoom in and out in virtual mode, too), go to the Presenter sidebar, and experiment with the Silhouette, Round and Portrait mask tools to see how you prefer to frame yourself. Our virtual green screen performance has improved a ton with our Beta 3 release—it more accurately detects your silhouette with less amoeba halo—and as with everything else, it’ll keep getting better.


Move around, shrink yourself, and ghost

Try clicking on your face in the main mmhmm window (aka the Stage) and dragging yourself around. If you have a trackpad, you can also use the pinch-and-zoom gesture to make yourself shrink and grow. Scrolling up and down with two fingers lets you gradually fade into oblivion.

You can also play with these functions in the Presenter sidebar. Try turning yourself into a semi-transparent blue holograph from Star Wars. Those guys knew how to work remotely!


If you're having too much fun making yourself shrink and fade and change colors, just hit Reset in the Presenter sidebar, and you'll pop back to normal. (The hot-key for this is ⌘-R.)


Get a room

Use the Rooms sidebar to choose (and change) whichever room or background suits your fancy. The first nine rooms have keyboard shortcuts (⌘-1 to ⌘-9) if your mood changes fast! You can even make your own rooms—just click Manage to add and customize images and videos.


You can also play around with Dynamic Rooms—they’re the ones with a white play button. These are beautiful, animated backgrounds generated in real time with code. You can customize these according to your style, and because these use way less processing power than video files, your computer won’t sound like it’s trying to lift off.


Show 'em your stuff

The slide tray below the main stage is where you put your ... slides. Try dragging images or movies to the tray. You can also push + New Slide on top of the slide tray to add media and share your screen. (When sharing your screen, you can resize and interact with your selected window normally, and the changes will be reflected in mmhmm.)

By the way: Choosing mmhmm’s virtual camera in your Zoom or Meet settings tends to work fine when you’re straight-up presenting, but if you want to display images and files in finer detail, we’ve dramatically improved the quality of screenshares so that your slides don’t look blurry.


There’s an added bonus to improved screensharing, too. Mmhmm already plays nicely with Zoom, Google Meet, and a few others, but this update allows for full compatibility with many more services—you can now use mmhmm with any video app that allows screensharing. Because sharing is caring!

We’ve also added a Presentation Tab Bar above the main stage so you can have multiple sets of slides open without juggling multiple windows. Just click + on the right side of the tab bar to add presentations, and ⌘-S to save them.

In the future, you'll be able to add many types of files to your slide deck, like Keynote and PowerPoint. For now, the best way to add your presentation to mmhmm is to export your slides as images.


Video killed the radio star

If you want to be able to run video in your slides like a pro, now you can. Video used to autoplay behind you, but we’ve loaded up some crucial controls: You can stop and start your videos at will, play them in a loop like a GIF, or use a scrubber to jump between segments—you know, all the things you’d expect to be able to do.


You can also use the virtual mic to broadcast your video slides with sound. This may sound simple, but it’s actually a pretty cool trick: We mix your microphone audio with the sounds being played in your videos, so you can voice over your content in real time. Why shouldn’t you be able to be a video and radio star at the same time?


Join a video meeting or stream your show

Once you’ve got your presentation set up and you’re broadcasting, you can change your video source to mmhmm Camera in apps that stream video, such as Zoom or Google Meet.

To get mmhmm to work with Zoom, make sure you’ve got the newest version of Zoom (5.1.2 or later), restart it, and select mmhmm Camera in the Zoom camera dropdown. To get it to work with Google Meet, please use Chrome or Firefox and restart your browser after installing mmhmm.



Gotta get away

When you open the mmhmm app, you’re broadcasting by default, which means you can join a meeting without having to turn yourself on. (No, Michael Scott didn’t write that.) Then, if you ever need to step away or want to stop broadcasting, just click Away to close the curtain on your presentation. Your screen will switch to a blue background with our adorable mmhmm bot and the friendly message “Be right back.” 


Sometimes two is better than one

Flying solo is fun, but multitasking can be hard. Copilot lets two people work and present together by linking up their mmhmm windows. When one person edits a slide, it shows up on their copilot's window. That way, you can speak while your copilot advances the slides, or you can present together with the confidence that no matter which of you the audience is looking at, your slides will always be on the same page.


We’ve also added Copilot Rooms (these are the ones with twin icons) so that when you’re in Copilot mode you can appear to be in the same location as your buddy.


Invite a friend

It’s no fun trying Copilot if your buddy doesn’t have access yet, so beta users can now invite friends to try mmhmm! Look for the paper airplane icon in the upper right of the app and click Invite a friend. We regularly refresh your invite total so that you can keep bringing your community on board.


Help, my text is mirrored!

If your slides show up reversed when you're looking at yourself in Zoom or Google Meet, don't worry! It looks normal to everyone else. This is a "feature" - ahem - in some video conferencing apps because they think you prefer to see yourself the way you would in a mirror rather than on TV. It makes pointing slightly easier at the expense of making it harder to read. You can keep this default setting (remember, no one else sees the mirroring effect), but if you don’t like it, just turn it off in your video app if they allow it (we know for sure this is something you can do in Zoom). We think you should turn it off. If your local news anchor can point appropriately, so can you!



The power flows through you

Become an mmhmm master with these keystrokes and short-cuts:

  • , (comma) toggles slides between off and the "default "slide view.
  • . (period) toggles slides between "default "slide view and "full-frame" slide view.
  • / (forward slash) toggles Hide Me on and off. Disappear super fast!
  • a toggles Away on and off.
  • Right and Left arrow keys move to the next and previous slides.
  • Clicking and dragging your head makes you move around the room without moving in your chair. Sorcery!
  • Pinching and zooming on the trackpad makes you shrink and grow.
  • Scrolling with two fingers makes you fade.
  • ⌘-R resets the video of you to default settings. This is your best friend.
  • ⌘-1 through ⌘-9 quickly switches between the first nine rooms.


Share your feedback

There's a lot more to discover, so explore and let us know how we can keep improving. Please send bugs to and feature request or other thoughts to We truly welcome your feedback, and hope you find mmhmm fuseful! (That's our unofficial motto, a combination of fun and useful. We stole it from Biz Stone.)
