Why are there "ripples" on large mkv's?

Question

Video

I welcome everyone! In general, such a thing. I download the BDRip movie in the best quality, or even the original Blue Ray. If you sit next to the monitor, then it is very clearly visible - Ripples on the video. c2n.me/3qXV9zU c2n.me/3qXVbgW c2n.me/3qXVjpx So for any movie, on large matrekhs (mkv), more than 8-10GB. Actually this is the question. So it should be, or it's in some kind of codec / player (I use it c2n.me/3qXV6Ja )

Answer 1

As I understand it, the problem is in the file itself. It is necessary, probably, not to download from the Internet, but to buy a disk.

Answer 2

This is a frank marriage of transcoding. And the one who ripal or did not watch what he was doing, or used a lamp monitor to control the results of transcoding.
The file size is not an indicator of the encoding quality, for example, for HD in the h.264 codec, 8-10 GB for a full-fledged movie is normal, but if you clamp the video in mpeg2, then 8-10 GB is very small, just such blots come out, or a mosquito net, depends on the settings of the denoise filters used when encoding.
There is another option: the film in the original SD is not of the best quality, they tried to recode it to HD. Here, what codec do not use, what filters do not use - bad SD will not become HD either.
