hi
i want to know what is the difference between number of 1080p copy of any movies,
i found 1080p movie size 45GB!
while other one the same movie same title"1080P was a bit lower, 22GB
the third was 11GB
what is the difference between them?

The movies you download are Ripped by encoders but the original ones are originals
I dont know how to explain to you, its easily understandable

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 encoders just decrease the bitrate and quality so that the size is decreased

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

If you say soo..

Because they want to see dick the size of a big pillow ramming into pussy the size of a toilet bow (on 50" LCD)

Still not worth it .. I'd rather have a real pussy in front of a pussy that I never get.

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.
