However, for YouTube video clip which embedded on blog or web page, viewers won’t have such flexibility to switch or upgrade the video playback to higher quality streaming, unless webmaster or blogger specifically embed a high quality and high resolution YouTube embed code on the website.
To allow visitors to web pages embedded with YouTube video clip to view and watch the video in high quality mode, webmaster has to use the hack below to embed the code that will stream from high quality video source, which stream as a MP4 (H264 with AAC audio) and encoded at 480×360. Similar to the hack to view high quality video on YouTube with &fmt=18 or &fmt=6 switch, publisher needs to append a switch to the YouTube embed code so that the Flash Player knows that it should play the video with high quality video streaming.
