(near) Lossless Digital Video - 5 inch disc

[kfbkfb]

Unlike PCM and Dolby TrueHD, Lossless (UHDTV/Ultra HD Blu-ray or
HDTV/Blu-ray or SDTV/DVD) Digital Video doesn't seem practical on a
5 inch disc for the foreseeable future.

My idea to minimize the Digital Video compression/data reduction artifacts:

Do an (original) frame by (compressed) frame comparison/subtraction
(make sure the difference between the original and compressed
Digital Video is low, perhaps some sort of algorithm that takes into
account the color and detail sensitivity of the human eye when
determining the difference).

This method would tend to minimize poor "encodes" and could even
be quantified in terms of a "maximum difference" number printed on the
disc package.
