YouTube HD (High Definition) informs YouTube of your preference to watch a video in HD (720p) by adding "
" to the URL. The addition to the URL is a convention set by YouTube, so you can expect as much of a speedy experience as YouTube offers, but without having to manually select the HD option every time.Note
: The approach employed by this add-on only works for the YouTube website. It does not work for embedded players on other sites. However, a version is being explored for embedded videos - there are numerous ways to embed a YouTube video (the official ways, and many, many
, unofficial ways). It will only be released if it passes an extensive Quality Control process.HTML5
This add-on now also contains an optional
preference (off by default) to load videos in the HTML5 player, using the same technique but adding "
". This option, however, conflicts with the HD option (see known issues).HD Embedded videos
Off by default. Enabling this setting allows embedded videos to be played in HD (1080p or 720p). It is experimental due to the numerous ways web developers embed their videos - I unfortunately can't cover them all. Not all websites follow YouTube's recommended code.
Use at your own discretion - though I use it all the time.
This add-on is intended to be lightweight, with minimal code, optimised, and with no feature-bloat. One known limitation is that videos automatically load in 720p, even if 1080p is available: this restriction is imposed by YouTube and how they interpret and react to the URL parameter. More information for developers can be found here:https://developers.google.com/youtube/player_parametersKnown Issue:
Any video that loads in the HTML5 player will not automatically load in HD. This is down to YouTube ignoring the HD parameter in the URL, and I am therefore unable to resolve it. However, as a workaround, visit www.youtube.com/html5
and ensure the "default player is currently used"
