We are serious about high definition. All of our porn reviews are focused on high definition adult sites. The purpose of this review site is to be very technical and informative regarding an hd website's high definition video aspect. A lot of "HD" adult sites tend to blur the line between having huge video or high bitrates, and actually containing high definition video.

Here at All HD Review we want to give you a little taste of what these high-def sites have to offer, and what you are getting into before you shell out your cash and sign up. Every site does HD a little differently.

HDV or high definition video on the internet is now somewhat easily accomplished, thanks in part to faster computers, and faster internet connections. With the rise of semi-pro based HDV cameras, adult sites have taken action and created sites featuring this new widescreen video technology. Offering clear, large, widescreen porn, for our viewing pleasure, the sky is the limit for HDV.

We at Allhdreview.com are dedicated to finding and reviewing the HDporn sites and bringing the answers you've asked yourself regarding the HD video they have available.

For all intents and purposes, we pay close attention to the High definition video available at each site, which is what we base most of our review on. Currently, there are two versions of HDV, 720p/30 (1280x720, 30 fps) and 1080i/p (1920x1080, 60 fps / 30 fps). For online adult sites, the 720p format seems to be the standard. But as computers and internet connections get even faster, 1080 video is on the rise.

If a site claims HDV, they had better have at least the 1280x720 sized hd video available at proper HD bitrates. Normal online HD bitrates vary anywhere from 3-9+Mbps. The 5-7 range is most common for online 720p.

There are multiple codecs availble for hdv encoding such as: WMV HD, H.264/AVC, and DivX HD (MPEG-4). The most common is WMVHD. The best quality is H.264.

Playing high definition content on your computer is no small feat. A large amount of data must be processed by your computer, and a powerful system will deliver the best playback experience.

If you computer drops frames (blinks/stutters while playing hd video) it may not be powerful enough to play hd content efficiently. Most hdv sites offer another lower end format. However, if you are reading this site, I assume, you have plenty of power at your fingertips. :)
