We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

im very new to ripping dvds and i want to know if there's anything i can do to improve the quality of my rips for my collection; when i was watching one of my dvds in my ps4 i noticed that the video quality was significantly better than my own rips; i followed the dvd decrypt [iso] to makemkv

i hope this is the right subreddit lol

Rip directly with MakeMKV if you want something truly lossless.

The picture on top (even not zoomed) shows all signs of upscaling, adding excess contrast and aggressive sharpening.

It looks like VLC is deinterlacing it automatically as soon as you play the ISO. The default method is probably YADIF which isn't meant for animation or film sources so set it to IVTC if it's a NTSC DVD or disable deinterlacing altogether to so it can return every frame as-is.

IVTC option does not return much different results from bottom screenshot

disabling deinterlacing makes it like this: [both of the screenshots are from this]

make screenshots from the same source as in both from TV or both from VLC. I have a feeling VLC is doing some stuff here and the same is happening on the TV.

i think now its not the rip itself, moreso the de-interlacing used
