Why does my screen recording stop automatically Mac

You are now in the main content area

Mac users can make use of two tools included with MacOS X for easily recording lecture slide presentations with voice over: the MacOS Built-In Screen Recorder and QuickTime Player.

Note: Both options produce .mov video files that quickly become large, so we recommend breaking up longer lectures into smaller video segments [by some logical arrangement relevant to the topic] to make for easier uploading [smaller individual files] and easier watching/taking in of information.

Record your screen with built-in screen recorder

With MacOS Mojave and later, you can record your screen with or without audio by pressing Command + Shift + 5 to bring up screen recording options. You can capture a still image [screenshot], record the entire screen, or record a selected portion of the screen.

You can open your lecture in PowerPoint [.pptx], Preview [.pdf] or Google Slides, then record only the slide area while accessing the rest of the screen area off-camera [to access slides, read notes, etc.].

Press Command + Shift + 5

The On-Screen Controls appear at the bottom of the screen, just above the Dock:

  • Choose "Record Selected Portion"
  • Drag the corners of the selection box to fit your slide area.

Click "Options" in the On-Screen Controls to change these settings:

  • Save to: Choose where your recordings are automatically saved, such as Desktop, Documents, or Clipboard. You can also Save to: QuickTime if you want to review and/or edit the video immediately in QuickTime Player.
  • Timer: Choose when to begin recording: immediately, 5 seconds, or 10 seconds after you click to record.
  • Microphone: To record your voice or other audio along with your recording, choose a microphone.
  • Show Floating Thumbnail: Choose whether to show the thumbnail. Showing the thumbnail after recording stops allows quick access to trim the video [does not apply if you opt to Save To: QuickTime].
  • Remember Last Selection: Choose whether to default to the selections you made the last time you used this tool. Enabling this option is useful when recording multiple short videos from a single, long presentation.
  • Show Mouse Clicks: Choose whether to show a black circle around your pointer when you click in the recording.

Click the "Record" button to start recording. A small Recording button will appear at the top.

Click the "Recording" button at the top to stop recording.

Click the thumbnail that appears in the lower right corner immediately after recording stops.

If you wish to shorten the video clip at the start or end, click the "Trim" icon in the upper right corner of the Preview screen to display the timeline.

Click the handle [double vertical bars] at the start or end of the video clip in the timeline and drag to shorten.

When changes are complete, click the "Done" button at the top right of the Preview screen.

Screen recordings will be named Screen Recording [DATE] at [TIME].mov and saved in the location specified in the On-Screen Control Options.

We recommend renaming the file to something descriptive [e.g. in this case CAT101 Week 9: Kitten Care - Lecture Slideshow.mov]. If you wish to make other edits, such as splitting the video clip or appending another video clip, you can open the screen recording video clip in QuickTime Player.

Share audio and video using Google Drive

When you upload certain media files to Google Drive, it processes them in such a way that they can be played back right in the browser sort of like YouTube. This is why we recommend uploading large media files to Google Drive instead of D2L Brightspace.
