Returning from WWDC, developers will likely be spending a lot of hours watching and re-watching session videos. If you’re like me, you love to listen to podcasts and audiobooks at 2x playback speed. QuickTime X for Mac can also do this, but it’s not immediately visible.
While watching a video, hold the option key and press the fast forward button. You’ll see the speed start to increase. There’s a bug that’s persisted in Yosemite that drops the audio when it hits 2x. To work around this, just simply move to 1.9x speed and stop there. If you find something interesting that you want to re-watch, you can hit the space bar to pause the video. Hitting the play button will reset the playing speed, though.
This is a great way to quickly move through any lecture-style content that you are playing in QuickTime.
