There seems to be this ridiculous notion that permeates the 'back up' community that you can drop the bit rate to the absolute bare minimum and somehow retain almost all the original quality. If the BD could have been encoded at 4-5 mbps to begin with, and the authoring house is starting with mastering quality source, then they wouldn't have bothered to encode at 25-35 mbps to begin with.

i have to be honest with you, if you can look at a 4-5 mbps 1080p re-encode of a blu-ray on a 50' hdtv and you think it looks close to the original BD then perhaps you either need a better quality tv, to adjust your tv or get some cataract surgery ASAP. I have alot of m2ts files that are obviously BR rips that are under 4GB 1080p AC3 audio that are between 40 kbps and they look close to BR on my Panasonic 50'. It creates a variable bitrate file that gives it all it needs in the fast action and throttles it down in the slower/less complex scenes. So.without a 'standard'.what's a guy to do? I prefer using constant quality settings in my applications.

So the bitrate requirements from one movie to the next (or even from one scene to the next in the same movie) could vary wildly. Lots of motions, lots of bitrate required.little motion.little bitrate required. Digital video compression works by taking frames of video at set intervals and just tracking the differences from frame A to frame B.

depends on the bitrate chosen and whether it is appropriate for the source.Ī solid black background with someone talking is going to require less bitrate than a busy street scene because there is less movement from frame to frame in the first scenario. The reason some 'HD' looks good and some looks very soft/blocky/etc. No matter how low/high the bitrate, they can still be called 'HD'.

As has been said before, 720p and 1080p are simply resolutions (1280 x 720) or 1920 x 1080)
