"Motion" App features

Your mac has screen recording functionality built-in, in the Screenshot application, and also in Quicktime Player.

You can launch Screenshot by pressing Command-Shift-5, click on one of the choices to record the whole screen or a selected area, and press record.

Motion itself does not do screen recording, but of course you can record what happens in Motion as described above.

Hi

In macOS, all your applications are in the applications folder. If you can't immediately see the quicktime player on your system, then go to your applications folder and check there. From there you can shortcuts to your desktop and add to your dock.

The screen recording app that uses the cmd shift 5 shortcut is called Screenshot. It records voice by default. When you enter the app with the keyboard shortcuts, you should see an overlay UI appear. Use the options menu in that UI to set your audio and microphone preference. Note that Screenshot was introduced with Mohave, so it will not be available in Sierra mac.

For the Sierra mac, there are a number of alternatives out there, many of them for free on the mac App store. I personally use Loom.com - which records and then lets you share a link for others to view.

I actually use Loom as much as I can, because the recordings are saved in the cloud (you can download anytime to your mac)...and this saves a lot of space. Screen recordings directly from quicktime or from Screenshot go to your hard drive, and depending on your settings, can start to hog a lot of room.

I think (not 100%) sure, that you can still record through quicktime on the Sierra, as that function was already available before Mohave and Screenshot. If you open quicktime and go to the file menu - you should see options there to record your screen.

Yes, you can do screen recordings in Quicktime Player in Sierra, at least if I remember it correctly; or if not, the old QuickTime Player 7 can (if you have it; it does run in Sierra, but I am not sure if it was included or was just there on my mac.

As to space on the drive, I don’t think that is a limitation at all. In fact, you can choose the location, and you can of course also copy things to the cloud afterwards if necessary. The initial recording will always use RAM and some space in the drive, regardless of where it is saved in the end.
