The movies you download are Ripped by encoders but the original ones are originals :S
I dont know how to explain to you, its easily understandable :S
 
The 45 GB copy that you're talking about is probably the original, uncompressed Blu-Ray version.

The A/V is compressed by encoders to reduce the size (w/o affecting the quality much) so that it can be distributed and easily downloaded by people with slow internet speeds.

The lesser the size, the lesser the quality - but unless you've a big 50 inch LCD with a good 5.1 hi-fi audio system, you'll not be able to gauge differences between the 45 GB copy and the 11 GB copy. So for most purposes, a 6 - 8 GB 1080p copy of a movie should suffice.
 
BIGGEST size un encoded...
Smaller size for example smaller then 25 GB encoded...

Encoded = ripped = remade, lower bitrate...

The trick is, you reduce the bitrate (and so is the file size) while trying to minimize the quality reduction. Too much bit rate reduction can be compensated by reducing the resolution, as well as setting up filters, and also a CRF (constant rate factor) which both reduces quality on high-motion scenes and increases quality for more still scenes, while maintaining the quality "same for a human eye".

The idea on CRF is, your normal human eye should not notice the quality reduction on high-motion scenes, because the eye takes more time scanning the TV screen/monitor to perceive the video. While on more still videos (eg. camera focused on heads talking) your eyes take less time to get the overall screen perception.

There is a limit on reducing bit rate and using CRF though, and that's when you see shitty encodes in small size.

IANAE though, but that's the general idea for me on encoding.

I've never understood why people are stupid enough to download such large releases .. The one at 700mb or 1400mb is perfect .. laughs

The reason is because when they view on a normal screen 700mb copies are fine, But when they want to view on their wide screen tv's the color is a bit off and screen is stretched so they need the 1080p encoded versions for better pixels.
 
Come on, its just 2 hours, you watch the movie and it finishes, downloading 45GB takes long time even in very high speed connections... just download a ripped one at 700~2GB and watch it.

But if you want to buy the movie its another story, nothing can be compared as the original ofcourse =)

On a decent TV/Projector with Surround Sound Setup it's very noticable. I try to avoid anything that's not 1080p if I can help it.

You'll really notice the difference on newer+bigger TVs.

Well, 11GB 1080p is the way to go. A few lesser Size will also suffice, but A 1080p release in 1 or 2GB will definitely not look good on a Larger Screen.

The 44GB ones would look amazing on large screens, and are also used by few Encoders to do further rips. ;)
Also that scene groups remove the Black Bars, which are present in 44+ GB Releases.
 
Sure, 700 or 1.5Gb rips are watchable, but you'll see (especially in the dark areas) the damage done by using compression.

Furthermore, the quality of sound (often DTS) is better on BluRay rips and more subtitles are included.

I guess it's just like MP3 and FLAC. MP3 is good to listen to, but FLAC may sound better (especially on higher quality systems).
 
damn 45gb movie, screw that... for normal movies i get the 700mb files, for movies that are worth it i get 1.4gb, thats it... only avatar was worth downloading at 9gb.

the dvdrips, BRrips 720p or 1080p are perfect quality in my opinion.

I'm just watching movies on my PC. If I want to watch a movie on tv, I will go and buy the movie in the store. Waste of time and hdd :P

I still do not see what role it plays. You're bloody demanding .. :p
