Open the video in QuickTime Player, choose View > Loop, then click Play. QuickTime will play the file to its end and start it again automatically. You can also press Option–Command–L when QuickTime Player is active.
Loop a video in QuickTime Player
- Open the file. Double-click the video in Finder, or open QuickTime Player and choose File > Open File. Files in iCloud Drive can be opened from their Finder location in the same way. Apple’s QuickTime Player guide documents both methods.
- With the movie open, choose View > Loop in the macOS menu bar.
- Click the Play button.
- Let the video reach its end. It should return to the beginning and play again without another click.
A checkmark beside View > Loop confirms that continuous playback is enabled. Menu names can be translated on non-English macOS installations, but the command is the same Loop function.
Use the keyboard shortcut
With a movie open and QuickTime Player as the active application, press Option–Command–L. This shortcut is specific to QuickTime Player’s playback controls, not a universal macOS loop command. If nothing happens, click the QuickTime window and try again, or use View > Loop. Apple lists the shortcut in its QuickTime Player keyboard-shortcut guide.
Turn looping off
Choose View > Loop again. The checkmark disappears, and the file will stop after its normal playback unless you start it again manually.

The video plays once and stops
Check for the checkmark beside View > Loop. If it is absent, enable Loop and press Play. If it is present but playback still stops, reopen the file and determine whether the movie itself reaches an error at the end or QuickTime has stopped responding; Apple’s guide does not identify one universal codec or container cause.
The shortcut does nothing
Confirm the exact combination—Option–Command–L, not Command–L or Control–L—while a movie is open and QuickTime Player is active. Use the menu command as the fallback.

What QuickTime’s Loop command changes
Loop is a playback command: it tells QuickTime to continue from the beginning when the open file reaches its end. It is not an editing, duplication or export operation, so it does not create a new video containing repeated footage or permanently alter the source file. Apple describes the feature as playing a video or audio file continuously in its current QuickTime Player guide.
Apple’s documentation does not specify whether the setting remains enabled after you close and reopen QuickTime. Check View > Loop whenever you open the app again if continuous playback is important.

Can QuickTime loop audio or only video?
Yes. Apple documents the continuous-loop command for audio files as well as video files. Open the audio file in QuickTime Player and use the same View > Loop command or Option–Command–L shortcut.
Can it repeat only part of a video?
The documented Loop command repeats the entire open file—from its end back to its beginning. Apple’s current guide does not document a command for looping an arbitrary selected section. If you need segment looping, playlist automation or a file format QuickTime cannot open, you will need a separately chosen playback or editing tool; those requirements are beyond QuickTime’s verified whole-file loop feature.
