Characters used to specify low/standard/medium/high quality/definition in video sharing websites I wonder what are the most common characters used in video sharing websites to specify options for the vide reproduction quality, in particular for this one.
For streaming video, it is common to say:


低清 (under 480p = 480 horizontal lines)
標清 (DVD resolution: 480p/576p)
高清 (720p or above)


Downloadable videos are sometimes marked as "超高清", which may mean 1080p (or even 4K), or simply a high bitrate 720p encode having excellent quality.
