How to edit a video using QuickTime on Mac

How to edit a video using QuickTime on Mac - macOS Guides

You might not know it, but QuickTime Player supports basic video editing tools, enabling you to trim a video then re-save it in various formats. This can be particularly helpful if you have a video saved on your Mac and you want to make it shorter.

Here’s how it works:

  1. Open a video in QuickTime Player.
  2. Press Command-T to access the trim tools.
  3. Drag the yellow handles to trim the video to its new length.
  4. Click the Trim button to save your changes.
  5. Press Command-S to save the video. It will be saved as a new video, so you will need to give it a new name.

How to use your iPad as a second screen for your Mac

  1. Click the AirPlay icon in the Apple menu, then select your iPad. If you don’t see the AirPlay icon, open System Preferences, click Sidecar, then use the Connect to dropdown menu to select your iPad.
  2. Your iPad should now show an extended part of your desktop. You can drag the mouse cursor and windows onto it, and use it like a second monitor.
  3. Another way to move windows (and apps) to the iPad is to hover the mouse over on the green fullscreen button in the top-left corner of a window/app, then choose Move to my iPad. The window or app will then instantly appear on the iPads display.
  4. To mirror your Mac’s screen, rather than extend it, click on the AirPlay icon in the Apple menu (which now looks like a blue rectangle), and choose Mirror.
  5. To finish extending your desktop, click on the AirPlay icon then choose Disconnect. Alternatively, you can tap the Disconnect button on your iPad.
Sidebar controls

Display a Touch Bar on the iPad

With Sidecar, you can show the Touch Bar from the MacBook Pro keyboard on your iPad’s display — even if your Mac doesn’t have a Touch Bar. To display this Touch Bar on your iPad:

  1. Open System Preferences, then click Sidecar.
  2. Tick Show Touch Bar, then use the drop-down menu to choose a location on the iPad’s screen.

Use an Apple Pencil

If you have an Apple Pencil with your iPad, then you can use it to edit photos, sign documents, paint, and manipulate objects. You can also use your Apple Pencil as a replacement for the mouse or trackpad to select things.
