I'm sorry, is this a special version of DVD that can store 4K video? Uncompressed?
4K BluRay discs are compressed with HEVC. There's no way to get consumer 4K video uncompressed.
Uncompressed 4K@30fps requires A 6000mbps data rate. BluRay caps out at 144mbps.
A 90 minute movie would be 4TB. BluRay caps out at 128GB.
Exactly. And a regular DVD caps at 4.7 GB if I'm not mistaken. Not even close.
That's just single layer - dual layer is something like 8.4 if memory serves (which it often doesn't...)
Yep, single-layer.
They're talking about 4K Ultra HD Blu-ray, which was introduced in 2016. The video is still compressed, but it's still much higher quality than DVD and Blu-ray, and can hold 60-100 GB of data.
But they wrote "DVD". I'm just nitpicking.
Ah, gotcha. It's annoying when people use "DVD" as a catch-all term for all optical media.
It is 😅 Words have meaning!
Exactly. I can't play Bluray disks in my DVD player. That's a pretty important distinction.
It's easy as long as you're okay with only being able to fit probably 1-2 minutes of video, the resulting disk not playing in any consumer player ever, and probably not even being capable of real time playback on a powerful PC with a fast drive.
😅 I'm not sure if I am, to be honest.
At the very least, it's still (generally speaking) higher quality video than streaming. It's not uncompressed, though.
Surely not? DVD is 576p/i (PAL) and 480p/i 💀. Not even 720p. 720p looks like garbage on a 4K display IMO. I really hope you are getting higher resolution from your streaming services than that, otherwise I think you're getting ripped off. (Streaming services are a ripoff to me regardless, but that's another point.)
Others replying to the comment included Blu-ray, so I did, too. I assumed it was a given to include that since others had already brought it up.
No harm done. I'm mostly just being facetious. 😅❤️
No, you're absolutely correct. Many people just don't realize how crappy the resolution is on DVD, and I would hate for people to buy some and be surprised at how bad it looks.
I ripped all of my DVDs because I have them, and combined they're something like the size of one or two 4k Blurays. So don't go out and buy a bunch of old DVDs if Blurays are an option for you.
Ha! That's pretty funny to me.
I think that would be a fun hobby for me, if I had the time for it. To gather a sizable blu-ray collection, and rip into a smaller size media library. There's so much to get into though, with all the codec options and settings and quantizing and shit. Mind-boggling when you haven't even started researching yet. 😅
Well, just start somewhere and optimize as you go. I've got an 8TB NAS (two 8TB drives in mirror), and it's not even halfway full, despite having a ton of DVDs and Bluray rips. I haven't bought many Blurays lately bags because Netflix was good enough, but I'm getting back into it.
DVD max quality is 480p, and it takes up ~2GB for longer movies at super quality m4v format with Handbrake (the first Hobbit movie was 2.5GB). 1080p Bluray rips are like 10x that.
I accidentally ripped a few with the wrong settings, but it's easy to redo it. So just get started, but make sure you have plenty of disk space. I use Jellyfin for watching on my TV and it works pretty well and was pretty easy to set up.
Yeah I have like 16 TB of raw storage (no backups, kek) but I'm nearing filling that up soon actually. 🏴☠️😅
But I do intend to set up a NAS and a Pi or something that talks to the NAS and serves Plex or (preferably) Jellyfin. Also it would act as a seed box.That would be sweet. I don't know where to start looking into what I need though. I want a Pi because it should run 24/7 and reboot very seldom, and it needs to be small because I live in an apartment and don't have a basement or anything like that. This is all so I can let my desktop computer rest when I'm not using it.
