Widescreen 480p video on TH-cam is 854x480 resolution, which equals 409,920 pixels. It would only be "about 300,000 pixels" if it was 4:3 aspect ratio (640x480 = 307,200). And The Wizard of Oz may not have been shot on an ARRI Alexa, but it was shot on film, which can easily exceed 1080p or even 4K resolution, depending on the quality and condition of the film. Thus, older movies which were shot on film will be able to have true 4K releases, while many newer movies which were shot digitally at 1080p or 2K resolution will never be able to have a true 4K release because the original cinema master is not 4K to begin with.
+vwestlife Ah, so that's why I occasionally see digital rereleases of old VHS videos. I've always wondering how in the world they took a VHS and made it a DVD... Never thought to consider the original media.
+Lady vor Edocsil 3K (let alone 4K) is definitely way too much for a 35mm film. Even at 1080p you can clearly tell the difference between a 35mm source and a 65mm source. Just watch the Dark Knight (Rises). The difference in sharpness between scenes shot on 65mm film and ones shot on 35mm is huge. Just make sure to watch in full blu-ray. That's quite important; low bitrate rips destroy all the 65mm goodness.
I guess Linus would have to explain that term itself again, regardless of whether he namedropped it or not. So there's no point bringing it up, and then intimidating people. Ofc he did refer to interpolation -- as the logical stuff "that can guess" (1:45-1:50) the pixels. Just easily and sneakily as you say!
Anolaana Seranaar The point is that IMHO you can't really convey much information about this topic at all if you don't at least explain three different cases: no interpolation (nearest neighbor), _some_ form of interpolation (let's say linear to keep things simple) and the ... let's dub it "fancy shit" upscaling in TVs and Blu-ray players that uses all sorts of prediction algorithms. If you don't do that, you have to explain all kinds of upscaling as "the hardware is guessing what pixel goes there" which is exactly what happened in this video. I therefore doubt it taught people who don't already know this any useful concepts.
Penny Lane Hmm. I would question the value of the distinction of "interpolation quality", seeing as though this video is constrained by the time and target audience. To be fair, you can explain that without namedropping "interpolation" as well. But most importantly, as a scientific-communication-education-type-person I would think it's important to not go too deep, nor go over peoples' heads. That is just a waste of time -- because people just turn off and switch away.
+Mateusz Wojtkiewicz Wizard of Oz was shot on 1939-era 35mm film, which makes if far inferior to modern digital cinema cameras. Not even close. Modern 35mm film on the other hand...
What the hell is wrong with people? Before this video, everyone was like, "We want Linus back. Where is he?" Now that he's back, nobody cares one bit. So I'm gonna say it. Welcome back, Linus. We've missed you.
+Christopher Newman “Big Tank” I'm surprised people don't use mpc-hc with madvr, and instead prefer to use the usually bad filters of k-lite codec packs and similar solutions.
Y'know, after discovering this channel I thought it'd be nice if Linus made a video explaining MIDIs, something like "MIDIs As Fast As Possible". Afterall, they've been pretty important for both computers and home consoles in the past!
I just wish that Integer scaling was more popular. I don't care if if has black bars around it, I want my retro games PC games looking pixel sharp, not this crappy bilinear filter that makes the text so blurry you can't even read it. You WOULD think that such scaling would be the least process intensive.
OMG they actually answered my question. I asked like 3 months ago but I guess production schedule dictates that it would take that long. Thanks guys for the great response!
I really hope we can someday develop displays with re-sizable pixels to get around upscaling, just like in the days of CRT, but without any of the tradeoffs.
Well. Upscaling can be an very useful "plan B" in some situations. The first is, for exemple, if your console or even your gaming PC isn't powerful enough to display 4k resolution. It can happen. Currently, the only video card that can run the most recent games in native 4k, at high/very high settings is the GTX 1080ti. And it's, for now, unaffordable for most consumers. however there is a trick: closest the native resolution is to 4k, better the upscale. For exemple: if you play a game at native 1920x1080p, the upscaling factor will be 4 times that resolution, but if you play at 2560x1600p the factor, will be only 2x. It will just shrink the pixels and multiply the ammount by the scale.
TehOnlyShoe Yeah the UK one. One of the kids looks like Linus to me. It' uncanny. Now the really dumb one, but the dumb one. I swear he's a linus clone
I find it kinda funny that his squarespace add in this one explicitly says their site always works but in the last video I watched, Luke broke the web store. I get why you'd skim over that because it wasn't squarespace's fault, but it's still pretty funny
I undestand this is a "As Fast As Possible" video but I thought you were going to explain more how it knows which pixels should go where but I can wait for a video from computerphile and others channels that do more detailed videos and don't have the time of the video as a problem
+Ryan Gunn More or less. It's all about how you calculate the color of the missing pixels. There are some pretty amazing algorithms for it (e.g. bicubic interpolation). That's what makes the difference.
The word "UPSCALING" should ONLY be used to describe going from actual DVD to actual BLU-RAY to actual 4K and so on. "UPCONVERTING" should be used when a medium is altered. With out this distinction I have trouble talking to everyday people about my DVD player and its HDMI output.
Great video, I'd like to say though, that the wizard of oz probably isn't the best example. Most old filmstocks look surprisingly sharp on modern scans, technicolor maybe even more so than others.
+Reiden Lightman Yeah and as an american I feel as I shouldn't be getting 1.0Mbits per second that costs $45 a month, but what's worse is that it's the best we can get here and there's no other companies outside at&t.. The best I've seen here is 1.3, and we pay for 1.5, and usually when everyone is using it it's at .4-.6. depending on time..
Thats not how standards work. It would be like calling DVDs CDs, and saying that they are both indeed compact discs, so why shouldn't they both be called CDs? Yes, Standard Definition is a crappy name from a modern perspective, as standards change, but back then it made perfect since. Remember that 480i was the standard definition for video all the way from the late 40s til the late 90s, and it didn't seem like an upgrade in the standard was realistic till the mid 90s.
I have a ton of 480p video on my server stored as MKV files with zero compression. I have Plex running on my server and it's setup to push everything out at 1080p with max quality. I was surprised just how good 480p movies looked on my 55 inch TV after Plex pushed it out. Works pretty damn good. Not as good as my bluray MKV files, but still way better then expected.
A while back I noticed VLC player did this o.o 480p upscaled looks pretty good and a lot smoother - especially on anime with still shots. Movements make the lines blurry again.
This video only seems to talk about upscaling as a positive thing. I understand the point was to talk about why you might want a DVD player or 4k TV which totes it's 'upscaling quality', but I recently had a run in with the nastier variety. So, I don't have TV service anymore, but I do have an older HD TV. Since I do watch a lot of TH-cam videos and Netflix (which is essentially my replacement for TV service), I decided I could get some use out of the TV by getting Chromecast so that I don't have to be at my desk to watch TH-cam. The trouble is that it would upscale only TH-cam content on me. And when I say 'upscale', I mean that the image would be bigger than the screen could render; cutting off some on every edge. Netflix worked fine. Google searches on this problem said to 'change the image format on your TV'. Trouble is that the earlier HD TVs would automatically adjust the image. If you wanted to change formats, you needed to do so at the source. Further searches on what to do if you cant change the format resulted in the extremely unhelpful comment of 'just get a new TV'. No. I'm willing to spend under $100 to fill this niche role, but not more. And what is the point of Chromecast if you cant make old, dumb TVs smart? Anyhow, I did figure out a solution. I didn't see this posted anywhere, I just figured it out: get a HDMI to VGA and audio adapter, then plug those into the TV. The TV doesn't upscale on the VGA input, it's 1-to-1.
But when you watch 480p videos on the phone which has FullHD 1080p resolution, they look better than watching them on 23" monitor with same FullHD 1080p resolution.
+1sonyzz That's because the phone's screen is OBVIOUSLy much smaller. You'd have to get your eyes physically within 2 inches just to see about the same pixelation as you would watching that 23" 1080p monitor at around probably 1 foot. It's all about pixels dealing with screen size versus distance from your eyes.
+JohnByeBye This little spelling correction speaks oodles about how popular culture is changing everything yet...you should probably fight the fights you can win. Kudos for trying!
nice ending, though a quickie could be made concerning why the likes of Ben Hurr, Baraka and Samsara will be out in 8K eventually and why some other films will never benifit from more than 720P, specially if shot on 8 or 16mm
I remember when HD-DVD and Blu-ray where in that fight. And you had upscaling DVD players. "just as good." No, not just as good, yes it had HDMI or another HD output method but it depended upon upscaling and decoding MPEG2. And one of the big changes HD-DVD and Blu-ray brings is MP4. It is just a better codec able to put more quality in the same amount of datastream. Still for a while, upconversing a DVD was also a third option. Well nowadays we have allot of streaming media and we are even getting dependant upon HVEC, because MP4 just doesn't cuts it for 4k Streams.
Except Linus - film stock (depending on the size, quality, etc.) contains typically more information than 1080p video, and often as much or more (again depending on age, size, type quality) than 4K. The thing with analog signals (and yes, this is taking it to a theoretical extreme) is that they can, again theoretically, capture at what would equal an infinite bitrate in a digital format. So to say that 1080 or even 4K will expose the technical limitations of, as you cited for example, The Wizard of Oz, you are incorrect. The Technicolor print of that film contains both more color data and equivalent pixel density than a 4K compressed format can reproduce. The digital enhancements to the film for Blu Ray 1080p release were entirely restoration related to age, not any form of wizardry generating extra color or pixel data (except what was lost to damage). This is why older digital films, such as the Star Wars prequels will never exist in a true 4K format - the data simply doesn't exist because they were captured on a medium with an inherent and arbitrary quality limit, whereas even certain 70s cheap TV captured on film (case in point, Dr. Who: Spearhead From Space) can meet or exceed the quality capacity of modern digital formats. I'm not trying to be hipster here, but the automatic assumption that "new is better" or "digital is better" doesn't apply to all media, at least, not yet. At the consumer level? Sure. Most DSLRs still capture more picture data than consumer-grade 35mm film did 20 years ago. Phones capture much more information than VHS-C camcorders of long past. But at the professional level, digital capture is still just a smidge behind the pinnacle of analog capture technology, in terms of maximum data stored - and to say that high-grade film, even film nearing a century old, will somehow limit the quality of a digital release, right now in 2016, is to fundamentally misunderstand the entire basis of the medium.
+Salamand3rTech Lol, at the moment he mentions the Arri Alexa and Wizard of Oz I knew he was shooting himself in the foot, came here just to see if this was already mentioned, of all the films he choose one that was actually already scanned at 8k which might be a bit overkill for 35mm.
Sometimes - actually, pretty often, Linus gets a bit caught up in digital media. I actually blame whoever edits or writes the scripts as much as I blame him. It's a common misconception that digital is always superior to analog media, but people like Linus should be dispelling misconceptions like that, not mindlessly repeating them. He really needs to hire a geek over the age of 40ish to add some perspective to some of this stuff.
I heard that 1080p blu Rays look better on a 4k TV than on a 1080p TV because of upconversion? True or not? I know standard def looks like crap, but I heard normal HD scales better with 4k
+PhaseSkater If you scale it with a good up-converter like MadVR, it can look a bit sharper. Ultimately, though, you're not getting any more detail out of the picture.
Somehow Linus always reminds me of the Doctor, don't really know why. Maybe because he's always talking about things i don't have the slightest clue of and he takes them as natural...
What about using DSR in video games ? Why does using DSR for 4K, on a 1080p monitor, look better than native 1080p gaming ? What is scientifically going on there ?
The Wizard of Oz was shot on 35mm film, arguably superior to an Aria Alexa. You can get clean 6K scans from 35mm negatives assuming they've been properly archived and cared for. You can get 8K+ from 65 and 70mm film.
The wizard of Oz was shot on triple 35mm Technicolor so it may theoretically be possible to make a 24k master out of three 35mm 8k scans(about the best you can get from a 35mm master) so the Arri Alexa can suck it Linus.
![ILLSLICK - KILLSHOT REMIX [FULL VERSION]](http://i.ytimg.com/vi/RIK8RrqIAzE/mqdefault.jpg)

I pretty much agree, however I've heard, that scanning 35mm film stock above resolutions of 3K basically just ads grain...

So upscaling explained without even once using the word "interpolation." This was again an example of "faster than possible."
Many years dealing with 480p and 480i and they didn't even mentioned the darn term.
+Penny Lane I have a feeling he specifically tried to avoid this term

I really hope we can someday develop displays with re-sizable pixels to get around upscaling, just like in the days of CRT, but without any of the tradeoffs.
+DeusGladiorum

WoW, Linus, you are back! Hurray :D
Well. Upscaling can be an very useful "plan B" in some situations. The first is, for exemple, if your console or even your gaming PC isn't powerful enough to display 4k resolution. It can happen. Currently, the only video card that can run the most recent games in native 4k, at high/very high settings is the GTX 1080ti.

It will just shrink the pixels and multiply the ammount by the scale.
Shooting the Wizard of Oz on a digital camera is a bad move. Most movies should be shot on regular film so that they can be remastered.
4K has over 9000 individual pixels per pixel, making it the better upscale option for most board room projectors.
+The Hoax Hotel That's 65% more pixel per pixel!
4K has in fact more than 9.4 MILLION pixels

+Marcello Morales Space them out, then fill in the gaps with pixels in a gradient from the one pixel to the other. Totally guessing. :p

+1sonyzz That's because the phone's screen is OBVIOUSLy much smaller. You'd have to get your eyes physically within 2 inches just to see about the same pixelation as you would watching that 23" 1080p monitor at around probably 1 foot.
It's all about pixels dealing with screen size versus distance from your eyes.
Woah! Linus with the actual segue for once
So the slideshows are in a button that Linus and luke control with their pocket. I thought they were video edited.
Lol I love how he segways into the sponsored content.
+MattsMotorz *Segue ;)
Lol Thanks
+JohnByeBye This little spelling correction speaks oodles about how popular culture is changing everything yet...you should probably fight the fights you can win. Kudos for trying!
+G “Jerry” Henrickson ?
I only watched the 2 year long ad so I could see what Linus could possibly rant on for that long.
nice ending, though a quickie could be made concerning why the likes of Ben Hurr, Baraka and Samsara will be out in 8K eventually and why some other films will never benifit from more than 720P, specially if shot on 8 or 16mm
I remember when HD-DVD and Blu-ray where in that fight. And you had upscaling DVD players. "just as good."
No, not just as good, yes it had HDMI or another HD output method but it depended upon upscaling and decoding MPEG2. And one of the big changes HD-DVD and Blu-ray brings is MP4. It is just a better codec able to put more quality in the same amount of datastream.
Still for a while, upconversing a DVD was also a third option.
Well nowadays we have allot of streaming media and we are even getting dependant upon HVEC, because MP4 just doesn't cuts it for 4k Streams.
Wait so those 4k hd quality movies that were promise to me aren't truly 4k!!!
+Kornelius Heydrich only if they were on 35mm film they can be made 4k
+Kornelius Heydrich it depends on how they were shot
Someone told me that pre digital film from cinemas are such a high resolution that it is only now tvs are catching up is that right ?
Linus senpai he is back!!! GLORY!!!!
480p is NOTHING pitted against GLORIOUS PAL 576p!!
720p for 15" or lower sizes, 1080p for 16" to 24", 1440p for 25" to 36", and finally, 2160p for 36" or more
And apple offers 27" imac with 4K or 5K, that is 5120x2880 / "2880p"
YEAH ITS LINUS!!!!!!!!!!!!!!!!!!!!!!!!
Except Linus - film stock (depending on the size, quality, etc.) contains typically more information than 1080p video, and often as much or more (again depending on age, size, type quality) than 4K.
The thing with analog signals (and yes, this is taking it to a theoretical extreme) is that they can, again theoretically, capture at what would equal an infinite bitrate in a digital format.
So to say that 1080 or even 4K will expose the technical limitations of, as you cited for example, The Wizard of Oz, you are incorrect. The Technicolor print of that film contains both more color data and equivalent pixel density than a 4K compressed format can reproduce. The digital enhancements to the film for Blu Ray 1080p release were entirely restoration related to age, not any form of wizardry generating extra color or pixel data (except what was lost to damage).
This is why older digital films, such as the Star Wars prequels will never exist in a true 4K format - the data simply doesn't exist because they were captured on a medium with an inherent and arbitrary quality limit, whereas even certain 70s cheap TV captured on film (case in point, Dr. Who: Spearhead From Space) can meet or exceed the quality capacity of modern digital formats.
I'm not trying to be hipster here, but the automatic assumption that "new is better" or "digital is better" doesn't apply to all media, at least, not yet. At the consumer level? Sure. Most DSLRs still capture more picture data than consumer-grade 35mm film did 20 years ago. Phones capture much more information than VHS-C camcorders of long past. But at the professional level, digital capture is still just a smidge behind the pinnacle of analog capture technology, in terms of maximum data stored - and to say that high-grade film, even film nearing a century old, will somehow limit the quality of a digital release, right now in 2016, is to fundamentally misunderstand the entire basis of the medium.
+Salamand3rTech Lol, at the moment he mentions the Arri Alexa and Wizard of Oz I knew he was shooting himself in the foot, came here just to see if this was already mentioned, of all the films he choose one that was actually already scanned at 8k which might be a bit overkill for 35mm.
Sometimes - actually, pretty often, Linus gets a bit caught up in digital media. I actually blame whoever edits or writes the scripts as much as I blame him.
It's a common misconception that digital is always superior to analog media, but people like Linus should be dispelling misconceptions like that, not mindlessly repeating them. He really needs to hire a geek over the age of 40ish to add some perspective to some of this stuff.
My internet isnt even fast enaugh for 720p so....
SQUARESPACE
+Lukas Netzker You should
I heard that 1080p blu Rays look better on a 4k TV than on a 1080p TV because of upconversion? True or not? I know standard def looks like crap, but I heard normal HD scales better with 4k
+PhaseSkater If you scale it with a good up-converter like MadVR, it can look a bit sharper. Ultimately, though, you're not getting any more detail out of the picture.
And why is that video still 1080p and must be upscaled on my 4k monitor ?
yasss he's back
360p upscaling is life. alaska only has limited bandwidth ISPs...
Well, I always upscale my 1080p to 4K before uploading on TH-cam; but not for the better resolution; I do it for the higher Bitrate :^)
Somehow Linus always reminds me of the Doctor, don't really know why. Maybe because he's always talking about things i don't have the slightest clue of and he takes them as natural...
What about using DSR in video games ? Why does using DSR for 4K, on a 1080p monitor, look better than native 1080p gaming ? What is scientifically going on there ?
This video should be called Upscaling as that is the proper term while upconversion is jargon
The Wizard of Oz was shot on 35mm film, arguably superior to an Aria Alexa. You can get clean 6K scans from 35mm negatives assuming they've been properly archived and cared for. You can get 8K+ from 65 and 70mm film.
Given the possibility, couldn't you avoid the blurry mess caused by upscaling by using Nearest Filtering?
The wizard of Oz was shot on triple 35mm Technicolor so it may theoretically be possible to make a 24k master out of three 35mm 8k scans(about the best you can get from a 35mm master) so the Arri Alexa can suck it Linus.
