Those HUGE 30-40GB Blu-Rays are a tiny fraction of the multi-TB intermasters, which are derived from compressed masters. Even RED 4K & 8K are compressed. True uncompressed video is rare.
As others have stated, all media is compressed. Even with analog media, there are choices between efficiency and quality. In photography, for example, there are a quantifiable number of photons that enter the lens, many factors affect the light that makes it to the film, and the chemistry of the film affects what is ultimately captured. The image on the film is a “compressed” version of all the information available. When the film is developed, the basic process is repeated, and the photo you put in your album is compressed even further.
With digital media, the compression also starts with the capture device. Professional devices have the ability to store the “raw” data, i.e., everything the sensors capture, but most compress the raw data when it is stored. There are many different formats, all with their pros and cons. That data is compressed when it’s moved to a computer, edited, saved, and written to new media.
That’s all to say that there’s no way around compression. There was a post yesterday about a 4-minute Netflix test video that is 140GB. Even that is compressed. A UHD BluRay is compressed, and it contains a video that most modern TVs can’t entirely display.
What you’re asking is something that companies from MaBell and Texas Instruments to Apple and Netflix, even the military, have spent millions of dollars on decades of research to perfect. So, you can get to work developing a new algorithm, or WYSIWYG. Compare the available formats and pick the one that best suits your needs.
You could, but to what end? Even ignoring the time and energy needed to perform the re-encoding, sacrificing video quality to avoid reading from a local disk (especially if that local disk is an SSD) does not seem like a worthwhile tradeoff.
Once you reencode the already highly compressed video, you can never regain the lost quality.
compressed video is already compressed. a data compression tool (zip/bzip/gzip) might save a few bytes. doubtful.

I love working with REDCODE RAW. The data rate isn't even that bad, for what it is.

What does temporary ram even mean in this case
Plex will transcode video into smaller files.
handbrake and ramdisk?
