Wanna watch a lot of WWDC videos in a short time? If you’re in a web browser, on a page like this one, you can run some JavaScript to speed up videos:<\/p>\n

document.querySelector(\"video\").playbackRate = 1.4;<\/pre>\n<\/blockquote>\n\n

And yet it’s 25 years after QT provided the foundational tech for this and not a single Apple AV app actually provides both of these in their most useful form.<\/p>\n
None of this is rocket science. Spoken word and video BOTH<\/p>\n
- need variable speed playback (properly LABELLED speeds would also be nice -- don’t know WTF Apple could never get this right)<\/p>\n
- need decent forward and backward jump buttons, ideally programmable, otherwise 15 sec each<\/p><\/blockquote>\n\n
It’s frustrating. The WWDC app doesn’t let you adjust the speed and doesn’t properly remember which video you were in the middle of playing or what time you were at. I eventually figured out that you can jump forward and backward 15 seconds when it’s in full screen mode.<\/p> \n
For most sessions, though, the slides and demos are not critical (and can always be viewed after the fact), so I’ve been using Overcast. It’s a few extra steps to download the videos<\/a>, convert them to audio, and upload them, but playback works so much better, especially with Smart Speed.<\/p>\n\n

Nice! Also you can make this into a bookmarklet<\/a> so that you can speed up videos on iOS as well.<\/p>\n<\/blockquote>","protected":false},"excerpt":{"rendered":"
