Bitrates Bluray,DVD & Streaming or downloaded HDVideo

Alot of people pay extra for HDVideo streams or downloads. You may be suprised but  after watching multiple sources and monitoring bitrates that the   HDvideo is superbit DVD bitrate at most and most others are streaming not much better than a DVD video.

A DVD streams at a max of 10mbps but realtime playing you will only see 5-7mbps and the audio on DVD streams at 448kbps.

The best Downloaded HDvideo I purchased scored between 7-10mbps and the audio was at 664kbps. This is only slightly better than the Superbit DVD of Panic Room I viewed. Keep in mind the HDVideo Bitrate was not a solid 7 or 10Mbps like the superbit dvd was I found the bitrate to drop down to the 800kbps and a few times dropped to 600kbps. A SuperBit DVD is pretty much what it says it’s better quality becuase of the higher bit rate this was canned after HD-DVD and Blu-Ray hit the market I only have 1 SuperBit DVD….Every once in awhile you can find these SuperBit DVD’s on a Walmart shelf.

I then viewed a Xvid encoded video that was ripped from a Blu-Ray disc this scored Audio- 381kbps Video-457kbps-2.2mbps

Point of this blog is to look at this before spending the extra harddrive space or the extra $$ for a HDvideo that really isn’t High Definition.

Keep in mind sometimes higher resolution doesn’t mean better image quality especially if the bitrates are no better than DVD video. Here’s the rates I marked.

DVD Video- Sound-448Kbps Video- 5-7Mbps  this is a fluctuating mark the reason for 5-7Mbps.

SuperBit DVD-Sound-755kbps Video 5.7-8.0Mbps

Xvid-Sound-381Kbps Video-457Kbps-2.2Mbps

Downloaded HDVideo Sound-668Kbps Video-7-10Mbps/ 7-8mbps being the most steady

Blu-Ray-Sound-4Mbps Video-20-40Mbps/20-30Mbps being most steady.

What really got me was the SuperBit DVD sound was much more superior compared to the HDVideos I watched. Clarity and loudness couldn’t be matched to the SuperBit only source that outshined SuperBit DVD was a BluRay video look at the numbers they speak for themselves. There is tricks that can be done to improve picture quality with less bitrates same with sound but in all no one can deny that more bps is going to have the better picture in the end.

Same can be said there’s no difference between Dolby Digital and DTS but when I listen DTS just sounds more crisp.

Great place to review pretty much every Blu-Ray released. Check it out
