Mkv same quality but different sizes. WHY?

[packing93]

Hi, i just downloaded two rips of the same movie, one is 29GB and the other is 16GB. they are both mkv and 1080p. I took a screenshot from the same frame of both rips and compared it, but they are the same quality, even the audio sounds the same. when pressing on codec information on vlc I see that both video and audio have the same specs (as expected). the only difference between the two rips are the size and the amount of softsubs, I know that subs dont take much hdd space so that cant be it. So my question is, why is the one bigger than the other and which one should I keep?

I don't understand why you would expect two files that are obviously different to have the same specs but...they don't have the same specs. VLC is simply not displaying the particular specs which are different; most likely the bit rate.

Download and install this https://mediaarea.net/en/MediaInfo/Download and open the files with it. It will show you the full specs.

Objectively, the larger file is "better" quality (probably) but, subjectively, you personally cannot tell the difference so is it worth you giving up extra disk space? Nobody but you can answer that for you; it's a personal choice. I wouldn't keep either one, I wouldn't have even downloaded them in the first place.

Thanks, I already used the 'mediainfo' program on the files before but couldnt find any difference, now i did it again with an updated version and I saw that the larger one has a overal bitrate of 34.9 mb/s and the smaller one has 19.3 mb/s.
If it is true what you say about that you cant tell the difference, whats the point of making a larger file with such a high bitrate anyway?

The key word is "you".

You might be a myopic pensioner with cataracts watching on an iPad.

Someone else might have perfect vision and an 85" plasma screen.

i.e. just because you can't tell the difference doesn't mean nobody else can.

Are you watching the fluidity from frame to frame? Or are you staring deep into the dark areas of a particular scene to see if there's really information there or if it has been lost in conversion? Those are some of the easiest ways I decide which copies to keep and toss. It is definitely not all about a crisp looking image alone.

Nope, I am using a high end pc with 6TB of hdd space and a 120hz gaming PVA screen.
As for the tv, its panasonic VT60 ,the kuro killer.
No apple trash for me.

I just looked better and its hard to see but the smaller one seems to be more fluid, the bigger one has less noise and looks less sharp.
Correct me if i'm wrong, I  remember to know that these things have something to do with the processing of the image and not the quality of the image itself.
