Rest assured that there are archivists ripping their discs losslessly somewhere in the dark corners of the internet. Hidden because the copyright mafia will otherwise ruin their lives.
- walterbell 10y agoWhat's the best software for lossless archival ripping?
- ZenoArrow 10y agoThis is an interesting one, in that most data on DVDs is already stored in lossy formats (such as MPEG-2 for video https://en.m.wikipedia.org/wiki/DVD-Video https://en.m.wikipedia.org/wiki/DVD-Video ). The best form of preservation is to rip the contents as a DVD ISO, which will use the same video and audio formats, as well as preserving extra features like the DVD menus. Any DVD ripper that can rip to a DVD ISO format and perform checksums on the ripped contents will suffice.
- eltoozero 10y agoh.264 or h.265 is going to yield a much better compression ratio for equivalent quality, even after transcoding formats. On the order of 2:1 or 3:1 vs MPEG2 format for DVD.
- ZenoArrow 10y agoLossy in top of lossy is never going to be the best approach for archival purposes, which is what the GP was looking for. If the question was about balancing quality and file size I would've given a different answer.
- HNSucksAss 10y agoNo. With sources as heavily compressed as DVD, you never want to recompress them. Rip the original stream and keep it. Of course, ripping DVDs is pretty silly these days if there's an HD source available.
- web007 10y agoI've generally used MakeMKV to get from protected-source to open-copy, but still as MPEG-2 streams without any loss / transcoding. That's not what you'd use as an archivist - you would want something that does structure-level copying instead, so you get menus and chapters and whatnot. Unless you're talking about archiving just the feature, then it's about perfect and lets you preserve everything you care about in a single file.
- theandrewbailey 10y agoMakeMKV preserves chapters.
- ldjb 10y agoI have used DVD Decrypter [0] (unfortunately Windows-only) to make ISOs from DVDs. All the menus are retained, so I can still access special features (image galleries, character profiles, etc.). I also hear good things about MakeMKV [1], which apparently allows some sort of lossless ripping of video files (I haven't used it, so I cannot confirm this), although the MKV format does not support menus.

- rodgerd 10y agoI'll second DVD Decrypter. I archive DVDs with that, then use handbrake to pull all the useful bits (the film and special features, or programs in the case of TV series) for Kodi.
- michaelmrose 10y agoWorks via wine although some disks stopped working in recent years with the software at all that is not with wine
- circular_logic 10y agoYou can just use bash to make a 1:1 copy: sudo cat /dev/sr0 > ~/example.iso
- germinalphrase 10y agoI once knew of a group like this. eventually, thy disappeared - but it was the most wonderful way to access otherwise unavailable arthouse and experimental cinema. I miss it.
- javajosh 10y agoI'm curious: how did they meet? Secure irc?
- shiftpgdn 10y agoLook up the history of what.cd
- zymhan 10y agoAnd now I'm sad again.
- Fnoord 10y ago(I'm not OP) Experienced the same. I never got into this via IRC. My main thing was music genres, but also on the side quite some non-fiction(documentaries), and a few fiction. I met some awesome people on Soulseek and went from there into DCPP and FTP. This was around 2007-9. DCPP being the frontend for the users. It was a gentlemen's club and from there you just meet different people who see your collection and who invite you into different circles. Back then, there was an auto trader app written in Java, using self signed SSL certificates (w/o pinning). I never understood why they didn't just use rsync over SSH, but it takes more than 1 person to change such habits.
- wingworks 10y agoAlso read the "how music got free" book, covers allot of that stuff.
- nemof 10y agosc? i used to knew a few groups like this that concentrated on obscure arthouse films, but i've long since forgotten their names about from sc. there was another one that had something to do with a crow i think. hmm.
