Interesting Information Of Encoding?

I started to get off topic in the 185TB Storage Tape Discusion so I will start a discusion on Encoding and compressing that supposedly a Pirate uses to stream BluRay movies that were originally 8GB in size down to 1.4GB in size while still maintaining 1080P qaulity and looks alright to the average user. Like John says, it is about Pixel Density, or is it about more? What do you think of this article and its lessons? Can anything be applied to our industry? By the way, I don't believe he uses the common software called HandBreak for his encoding and compression like author states.

Article

Lesson #1, THE CONTAINER DOES NOT INFLUENCE THE FILE SIZE.

Lesson #2, THE CODEC DOES NOT AUTOMATICALLY IMPLY QUALITY

Lesson #3 THE BITRATE DOES NOT AUTOMATICALLY IMPLY QUALITY

Lesson #4 FASTER ENCODING GENERALLY = LESS QUALITY, and avoid (cannot stress this enough) video converters (and some video editors).

Lesson #5 USE SINGLE CORE IF POSSIBLE*, USE SINGLE CORE IF BATCH PROCESSING

Lesson #6 BE AS LOSSLESS AS POSSIBLE WITH YOUR ORIGINAL CONTENT

Lesson #7 DO NOT DO FILE SIZE/ BITRATE BASED ENCODES

Lesson #9 DO NOT RE-ENCODE AT A HIGHER BITRATE FOR NO REASON

Lesson #10 Use filters and “effects”

Lesson #11 Single pass bitrate encoding is not necessarily worse than two-pass bitrate encoding


Lesson #3 THE BITRATE DOES NOT AUTOMATICALLY IMPLY QUALITY

Sure it does! It just doesn't ensure it...

Lesson #9 DO NOT RE-ENCODE AT A HIGHER BITRATE FOR NO REASON

I agree, though this lesson could be generalized to:

Lesson #9 DON'T DO NOTHING FOR NO REASON

if it weren't for the following inscrutable instruction

Lesson #10 Use filters and “effects”

Any? Why? Just for No Reason?

Did you read the article (Click on the word Article as it is a link)? Or just the Lessons I pasted? If you read the comment section, some pretty good stuff in there also. I was surprised about the filters and effects and what it could do.

Sorry, missed the link, reading...

Whole article link is here as I made the link sentence bigger this time.

Use filter and effects part -

Lesson #10 Use filters and “effects”

If you’re a hardcore file sharer who wants to keep the film in as much of its original form and detail, then too bad- “600mb 720p mkv” style ain’t for you. On the YIFY website he clearly states that he uses a combination of software and settings that work best, which will most likely include filters such as “contrast”, “cartoon” or “denoise”.

A light amount of Cartoon special effects will simplify colors, reduce file size requirements while making the film still seem high quality.

Contrast will help simplified colors look better.

Not only does denoise cancel out “noisy” scenes, it also helps compression significantly, because it also smooths out grains, which are bad for video compression. I had a personal experience with this, where I filmed s short walk down a mountain, then used a movie editor to give it noise. The resulting 5min 352×240 file @RF15 in similar AVC encoding settings occupied around 1GB of HDD. Noise is not good for compression, so use denoise filters.
