The genesis of the world premiere of Charice's music video for Louder:
It started as a leak on a Japanese cable TV. A recording of it was uploaded on YouTube, triggering complaints on the low video and audio qualities. Websites already started publishing their reviews based on that. The video director called via Twitter for waiting for the HD version that was going to be world-premiered on EW.com - that was yesterday. We still did not think it was HD enough but at least it was official. And finally, Charice uploads it on her own YouTube Channel and, yes, it is definitely high def. Charice herself tweeted about the upload.
This article "How does YouTube video view count work?" says that YouTube embedded videos using YouTube's own HTML5 or Flash player contribute to the video's count.
