VLC has a nice feature which allows to play videos faster/slower without affecting the audio pitch. Can this be somehow achieved for YouTube videos as well?

You can change the speed of the video if you are in the HTML5 beta program. I am not sure about the audio pitch.

For example, here is a non-scientific (opinionated) breakdown of the video

Outland Series Trailer | Premieres Wednesday, 8 February 2012, 9:30pm | ABC1

Outland Series Trailer example of speed setting

At 2x speed: There sounds like there is a bit of pitch change but I cannot tell for sure based on the accents.

At 1.5x speed: No audible change of pitch (at least to me)

At 1/2x speed: The voices don't seem to drop to the lower pitch you would expect

At 1/4x speed: The audio drops completely

Where is that option? I'm afraid I cannot find it... – Tobias Kienzler Aug 18 '12 at 11:23

Thanks for the screenshot. This does not show up for me I'm afraid (activated HTML5, using Firefox 14.0.1). What browser are you using? Maybe this feature is only available North America... – Tobias Kienzler Aug 18 '12 at 17:19
@TobiasKienzler Google Chrome Mac 21.0.1180.79. There are restrictions for Firefox (On Firefox and Opera, only videos with WebM transcodes will play in HTML5) I doubt it is location dependent – phwd♦ Aug 18 '12 at 17:23
I see, so I'd have to use Chrome. My current workaround is downloading the videos and then using VLC's speed-up which also adjusts the pitch... – Tobias Kienzler Aug 18 '12 at 17:25

If you're using Windows 8, check out Media Player Plus (available in the App Store). It allows you to open YouTube videos (or your own local music/video files), then slow them down or speed them up without altering pitch.
