Append the following parameter to the Youtube-URL:

144p: &vq=tiny
240p: &vq=small
360p: &vq=medium
480p: &vq=large
720p: &vq=hd720

For instance:

src="http://www.youtube.com/watch?v=oDOXeO9fAg4"

becomes:

src="http://www.youtube.com/watch?v=oDOXeO9fAg4&vq=large"

I found that as of May  2012  if you set the frame size so that the minimum pixel area  width     height  is above a certain threshold  it bumps the quality up from 360p to 480p  if you re video is at least 640 x 360   I ve discovered that setting a frame size to 780 x 480 for the embed frame triggers the 480p quality  without distorting the video  scaling up   640 x 585 also works in this manner  I also used the  amp hd 1 parameter  but I doubt this has much control if your video is not uploaded in HD  720p or higher    For instance    lt iframe width  780  height  480  src  http   www youtube com embed  VIDEO-ID  rel 0 amp fs 1 amp showinfo 0 amp autohide 1 amp hd 1  gt  lt  iframe gt    Of course  the drawback is that by setting these static frame dimensions  you will most likely get black bars on the sides or above and below  depending on what you prefer   If you didn t care about the controls being cut-off  you could go on to use CSS and overflow  hidden to crop the black bars out of the frame  providing you know the exact dimensions of the video   Hope this helps  and hope the Embed method soon gets discrete quality parameters again one day

You can use the YouTube JavaScript player API  which has a feature on its own to set playback quality    player setPlaybackQuality suggestedQuality String  Void      This function sets the suggested video quality for the current video  The function causes the video to reload at its current position in the new quality  If the playback quality does change  it will only change for the video being played  Calling this function does not guarantee that the playback quality will actually change  However  if the playback quality does change  the onPlaybackQualityChange event will fire  and your code should respond to the event rather than the fact that it called the setPlaybackQuality function   source
