We have a 1080p tag currently, which means that in theory we probably need 480i, 480p, 720i, 720p, 1080i, 4k etc.
That seems a little too specific to me for this type of site, and the list will only get longer. What if instead we use catch-all tags like hdvideo and ultrahdvideo instead and use synonym tags to point 1080p and its brethren at the former and 4k and its variants at the latter?
Similarly, a dvi tag could be used to point synonyms dvi-i, dvi-d, dvi-a at; we could handle versioned hdmi tags (hdmi1.0, hdmi1.1 etc.) as synonyms too.
Do people think this would prove too blunt a tool when it comes to searching for tags, should we allow proliferation of the specific tags instead?
