Values: 0 or 1. Default is 0. Setting to 1 enables HD playback by default. This has no effect on the Chromeless Player. This also has no effect if an HD version of the video is not available. If you enable this option, keep in mind that users with a slower connection may have an sub-optimal experience unless they turn off HD. You should ensure your player is large enough to display the video in its native resolution.
Values: A positive integer. This parameter causes the player to begin playing the video at the given number of seconds from the start of the video. Note that similar to the seekTo function, the player will look for the closest keyframe to the time you specify. This means sometimes the play head may seek to just before the requested time, usually no more than ~2 seconds.
