youtube widescreen video, enabled!

youtube widescreen video, enabled!

Remember this morning when I reported about widescreen on youtube?


Well I said that after I deleted my cookies, it went all back to normal 4:3…

Good thing I use a Macbook though… thanks to time machine, I got those cookies back, and after while of trial and error and woxxy as tester, I found out the secret to widescreen YouTube…!

This just works for Opera, as it is the only browser where you can edit cookies. (If you use another browser, skip this part and read further down about how to do it with javascript!)

  • Menu > Tools > Advanced > Cookies…
  • Use the search field to find youtube cookies.
  • Select VISITOR_INFO1_LIVE, and replace the code (value field) with “O0pMCBlwgBI” (without the quotes).

Now load a YouTube page and… voila! If all worked out, you should have gotten widescreen video :P, test with this video


EDIT: Thanks Milo for the hint with javascript, this is also a good solution, albeit your code does not work properly on some browsers.

  • Go to
  • Paste the following code into the address bar and hit enter
  • javascript:void(document.cookie="VISITOR_INFO1_LIVE=O0pMCBlwgBI; expires=9/9/2009 09:09:09;")
  • Load a youtube video, such as this nice HD video.

HINT: This is platform and browser independent. The screenshots show Opera on MAC OS X, but it could just as well be Internet Explorer on Windows XP. As long as you have a way to modify the cookies (for example, using the javascript injection), it will work.

    Very cool! A simple way to activate this in any browser is to open and simply paste this in the Address bar:
    javascript:void(document.cookie = ‘VISITOR_INFO1_LIVE=O0pMCBlwgBI’)

    How do I do it through firefox? When I uncheck the bars for cookies, then I can’t even stay logged in youtube. Please get back to me soon!

    embedding in widescreen format is not new. this guide just shows how to do it without embedding. it works also on non-HD videos.

    But its still coming in widescreen =/
    Sorry to keep on bugging you about this!

    Yea thats because the widescreen feature is now default in youtube. I’ll try to find out how to go back to 4:3 :P

    Is there any possible way to go back to the original? This looks really dumb. On firefox, at least.
