Widescreen 480p video on UA-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.

This should be the top comment.
+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.
+vwestlife
I pretty much agree, however I've heard, that scanning 35mm film stock above resolutions of 3K basically just ads grain...
+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.
Anyone notice the weird "hey" near 2:00?

+Hunter Ray (TheYoungerGamer) good spotting
I thought the voice said "dang"
Damn! That's why Linus voice is up-pitched!
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 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.
Downconvert his voice to a normal range for a human.

+Sukeerat Singh Goindi (Sukuu) *lol
+Scott Warren Nah,Linus is the Geddy Lee of tech :)
lololol
Well Wizard of Oz was shot on film thus making it superior to pretty much everything that's come out to this day in terms of "resolution" so...
+Mateusz Wojtkiewicz Film is overrated but still yea id would look great in 4k, the blu ray looks really good.
Aleksanderh It's isn't better than today's 6k but pretty much everything shown in cinemas right now is only 2k.
Mateusz Wojtkiewicz i know.
+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...
+Mateusz Wojtkiewicz Maybe 5 years ago, but not anymore. The vast majority of films now are shown in theaters in 4K.
how about a fast as possible explaining MP4 MKV Etc
+Derrick Mulder to add and how to open em some of em are hard to open wwithout the right program and which is best for best resolution
+Jonathan Laig im suprized you never heard of k-lite codec pack.... with mpc-hc....
www.codecguide.com/download_kl.htm
+Derrick Mulder So a fast as possible video file containers, if he added a fast as possible codecs with that I think that would make a good video.
+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.
that sound bite at 2:00
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.
I watched this video in 144p fullscreen just for fun :)
I watch it on 144p because of my bad Internet 😭😭😭😭
+Simon L I Feel YOU.
+Simon L In watched it in 360p because I'm using the UA-cam app...
I watched in 1080P on iPad mini 2 in the UA-cam app
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!
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!
0:24 "Recorded on a potato"
Linus, you crack me up man! xD
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
CRTs looked like crap when the wrong pixel aspect ratio was used but still better than the blurry and blocky look of LCDs and such...
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.
Thanks linus for showing videos that arent even out yet.
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.
1:33 "Mr Stark, I don't feel so good"
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 UA-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 UA-cam.
The trouble is that it would upscale only UA-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.
0:30 No Linus It's called dlss 2.0(or newer)
I question the statement "It's so easy that even I could do it." This is freaking Linus we are talking about here.
I watched this in 144p...
+Bradley Gibbs Stay strong.
zombiebirds I thank thee...
The WiFi reception in my room doth have me disturbed.

5:39... "So easy that even I can do it" ~ Linus Sebastian
The Wizard of Oz was shot in Technicolor which has a screen resolution of 125 million pixels which far exceeds an Arri Alexa.
the way he said on a potato
haha, I laughed so hard
when you get italian accent from somewhere
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.
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
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.
He has returned.
Anyone else seen The Inbetweeners? Linus is totally that one kid.
+Aj Koorstra I don't get you? Are you speaking about the UK version? Because, then, I still don't get you lol.
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
+Marcello Morales It could be another video?
+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
+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.
***** Heh, I meant that I was totally guessing, but it sounds like the algorithms are, too ;)
Someone hasn't activated their Windows 10 (1:03 right bottom corner)...
Linus is the first non cinema related guy i ve seen who prefers "Arnold und Richter"
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
UA-cam should have pitch control
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.
FINALLY LINUS. I avoid most videos from this channel if they don't have Linus.
Actually some DVD players can upscale Component, but most of the industry doesn't like to do it because of how easy piracy is through analogue cables.
LINUS IS BACK ON TECHQUICKE!
+Kelvin Techu-Chan Tran ikr
Should i watch more Techquickie? Linus: You Should!
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.
I really wish 640x480 wasn't called Standard Definition anymore. I really with 720p would be the new standard definition.
+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..
I watch 480p on UA-cam all the time. No need for 720p. Atleast not for UA-cam.
Hurriname I watch in 4k even though i only have a 1080p monitor, it looks better because of the higher bitrate
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.
Finally Linus is back here.
liked this video because the transition to square space. YOU SHOULD do that more often.
play the video...
see the linus...
but wait, it's a youtube ad!
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"
IDK why, but this video started in 240p. I thought it was an effect to prove his point for a bit
+MeroDN I had the exact same thing happen.
Wasn't finished being uploaded by YT yet.
RalphArwen
But it gave me the option for 1080p and it worked
Oh I thought you meant it only had 240, sorry.
RalphArwen There's no need to be sorry.
But as long as you are,
please subscribe! :-D 👍
(lol)
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.
1:30 Luke needs activation!
As a cinematographer, the segue at 4:32 was uh... awkward. Still lots of love for the channel though, Linus. :)
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 ?
WoW, Linus, you are back! Hurray :D
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
There are some really advanced upscaling algorithms out there, like "waifu2x" that requires a 980ti to watch upscaled 360p in real-time. It uses neural networking, whatever that is...
How'd he get through this video without referencing crime drama on TV or saying "enhance"?
1:33 mr stark i dont feel so good
For 4k TVs, a 1080p video should be scaled to where 1 pixel from the 1080p source equals 2x2 pixels on the 4k display. 720p might not scale as well but the scaling should be as close to perfect as possible. maybe it doesn't fit the screen perfectly (black bars) but there could always be an option to fit to screen with a warning that the image will be distorted
Nope. 4K is not 4 times 1080p. It's slightly bigger. 2160p has just 8.2 million pixels and 4K has 9.4 million pixels.
I got an ad that features linus nice
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.
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.
for once an actual seaway... wow im proud of you linus.
HEY! LINUS IS BACK/ THE KING IS BACK
can you explain crt upscaling or pixels? 480p content looks so much better on my crt than in a lcd of the same dimensions
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.
Linus is back! Finally!
What is that background noisy thing? Am I crazy or every techquickie do this?
Amazing video as always btw
Here's my version of upscaling - Set my CRT monitor to the native resolution of the video and then play it. It has the best upscaling logic out of all of my displays............wait a moment, CRTs don't need upscaling!
480p is NOTHING pitted against GLORIOUS PAL 576p!!
Ah upscaling...I have not so fond memories of this from my console peasant days.
LINUS IS BACK
Upconverse deez nuts.
Goteeeeeeeeem
Paul Andreas Allik No*
bluephreakr Did I type Up-converse or Upconverse?
+bluephreakr savage af
you don't deserve those 4 likes
how many people start skipping at 4:35 ? sorry, but i know everything about SquareSpace now, Lynda is also no stranger...
360p upscaling is life. alaska only has limited bandwidth ISPs...
Yeah but The Wizard of Oz was shot on film which has tens of millions of silver halide crystals. It could be scanned in 4K or 8K and still have resolution to spare.
+Grant Pluntze that depends on quality of that film
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.
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...
Do not expect to see 144p in a UHD Monitor, compared to 360p native, it still looks worse. I think.
Well, I always upscale my 1080p to 4K before uploading on UA-cam; but not for the better resolution; I do it for the higher Bitrate :^)
When you'd thought they'd run out of ways to advertise SquareSpace...
Speaking of upconversion, why do I have to upconvert FAP. I likes watched at 4k and down scaling to 1440p because of the added bitrate and "super-sampling". Even Linus argued that this is a reason to watch at a higher resolution than the display is capable of. Can we have 4k FAP back?
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 is back? :D
TL;DR It's a thing that tries to make lower resolution video look better on higher resolution displays. Just thought I need this for GOD DAMN TECH *"QUICKIE"*
"Hey"
1:59
just use madvr with mpc hc to watch movies. it's got godly algorithms för both upscaling and downscaling
so that it can look super crisp
I only watched the 2 year long ad so I could see what Linus could possibly rant on for that long.
The smooth 'you should'
linus is back
But UHD blurays are out now rite? They sell them on Amazon for 22-30 bucks a pop

Which will look better, 4K upsampled to 8K then downsampled again to 4K or native 4K resolution alone?
So. If you had a 1080p display that you were playing a 4K video on would it stay the same? Look sharper? or screw with the video? I'll use this video "Tempura Udon Noodles" as an example because at the beginning it shows a nice representation of how nice 4K could look. But, my monitor is something like 920p or 960p and I've never really experienced true 4K but the video looked all funky when I tried watching it in 4K. I'm not sure if it's trying to autocorrect itself to become sharper or if that's just how 4K looks. In the beginning, I thought it would stay the same because the monitor can only fit so many pixels onto the screen that it was made with, but now I think it might screw with the colors but make it sharper. But if that were the case there would be no point in buying a 4K monitor in the first place, so here I am in a bubble of confusion.
So your saying if in this age of 4K Televisions , which barely has any 4K content , the TV would start assuming pixels all the time based on that chips algorithm, and hence bad quality images ? So u suggest to go for Full HD TV's now rather than 4K?
MPC HC + madVR for offline videos(movies) of any resolution, if it's lower resolution then it doubles the picture or even quadruples it. For UA-cam always 1080p, I wish I had internet for that and I don't want my CPU to go to 90% just for a 4K UA-cam video. :)
+Филип Пешић Wouldn't streaming yt videos to like Vlc media player don't consume so much cpu? on youtube 1080p video is very laggy on my pc but when i stream it to vlc its smooth 60fps.
CinmarRS VLC's codec is not powerful enough to handle 4K, I tried it in every possible way. :)
I was using VLC for 5+ years and a friend of mine barely got me convinced to switch to mpc - hc + madvr combo to be honest.
Филип Пешић i see, sucks.
Linus is back! 😃
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.
Use needi3 upscaling on madvr if you want to upscale like the pros.
I live in Australia so I already watch in 480p and 360p :(
