|

Hi!
When comparing a 1080p Mkv ~8gb with bluray it seems a bit flater in many ways. What do you think?
What is the differense from a real blu-ray file?

A Mkv file is just a container for any type of video/audio streams. Quality can be a 1:1 copy of a blu-ray if the person that made the file did not encode the video or audio tracks. If the file is only 8gb then it is likely the video has been encoded. The mkv files I create from my original disks have no quality loss from the original disk. My file size for a full length feature film range from 16-40gb.

Video is already encoded and compressed on a Blu-ray - if a movie taken from a BD has been reduced down to 8GB, someone has cranked up the compression ratio significantly, which is where the decrease in perceived PQ comes from.
