I want to play videos in iTunes faster (1x, 2x, double speed, etc.) or maybe slower. How do I do that?

Right click on the file in iTunes and choose "Show in Finder." Then right click the file and open in Quicktime Player. In Quicktime Player you can choose the playback speed by using the A/V Controls (Command + K or Window>A/V Controls). From there, you can select the playback speed:

A/V Controls - QT Player

Alternatively, you could use VLC or another music player.

    And yes, it's annoying that you can trivially do this on an iPod/iPhone but not in iTunes. – geekosaur Apr 11 '12 at 0:22

    The Quicktime solution works with Quicktime 7, which is still available for download, as of 8/2014. It does not work with Quicktime 10. – user87872 Aug 16 '14 at 3:18

    @geekosaur how does one accomplish this on an iPhone/iPod? – ProductionValues Mar 1 '15 at 8:25

    That window is no longer in QuickTime... – Ben Leggiero Apr 5 '18 at 19:24

  1. Right click on the iTunes playlist and click Show in Finder
  2. Right click on the content in Finder and click Open with Quicktime player.
  3. While watching the video/movie press Command and then right arrow or left arrow to increase or decrease playback speed, respectively.
  • This doesn't allow slower, just faster or faster in rewind. 2x is the minimum setting, in either direction. – User May 3 '17 at 21:42

The Cmd+K shortcut no longer works in Lion or Mavericks.

Please see a post about increasing the playback speed in Quicktime.

The double arrow allows for integer increases in playback speed.

Quicktime Player allows you to play the audio faster, but not slower.

The chosen answer, by @daviesgeek, works for Quicktime Player 7 (Snow Leopard or earlier).

If you're on a later version (well, I only tested this on macOS Sierra and Quicktime 10.4), you can play it faster by doing:

  • opt + click-on-fast-forward-button. This will increase playback by 0.1x each time.
  • opt + right-arrow. This one increases from 1x to 2x to 5x.

You cannot play at a slower speed though (but you can play backwards at speeds greater than 1x).

  • So you can't do 0.5x speed. – User May 3 '17 at 21:43

Folks, you can download Quicktime Player 7, which is for Snow Leopard or later Mac OS, and works with older media files (as well as current ones, it seems). It has the variable speed functionality you're seeking.

No guarantees this link will work whenever you read this, but it's working now, Nov 2015: https://support.apple.com/kb/DL923?locale=en_US

(Why Apple removed this functionality from Quicktime, who knows.)

Once installed, then play the audio file by first locating it in Finder, and use CMD-click to "open with" Quicktime Player 7. Voila.

Works for me on Lion or Mavericks:

  • CMD+OPTION+ (right arrow) for 1,1x

  • CMD+(right arrow) for 2x

macOs Sierra users can use Opt - RightArrow in Quicktime.

You can control the playback speed of an audio / video file in your browser by creating a bookmark with the javascript code found here: https://webapps.stackexchange.com/a/86817/217003

javascript: var v = document.querySelector('video'); var t = prompt('Set the playback rate'); v.playbackRate = parseFloat(t)

I have done this with Safari Version 12.1.1 (14607.2.6.1.1).

I prefer to use Quicktime built into Safari instead of VLC, because slowing down audio / video files in VLC sound harsh.
