Sure, Progressive is better than Interlaced. But Interlaced wasn't introduced to be better. It was introduced because hardware wasn't fast enough to transmit progressive frames.

Why did films skip 2560x1440.
technicly they didnt. most films are/were shot in that resolution the upscaled/down scaled to fit a 1080p or 4k tv. also they skiped it due to it being an odd number
That's called 2.5K and is available on some devices like go pro's and drones.
+Elliot Kaufman it's called 2K and isn't used because 4K is a thing. 4K is a perfect multiple of 1080p while 2K is not, so 1080p can be "perfectly" upscaled to 4K. plus its a bigger number than 2K, easier to market, etc etc.
lol no its 1440p.
+scootbmx01 well, 1440p, QHD, WQHD, 2K & 2.5K are all valid as the standard is less well defined having only taken off in niche markets.
As someone who works with this I am happy to see that Linus didn't mess any facts up. Stamp of approval! Important to point out that 1080p24 (any movie and most scripted TV) can fit into 1080/60i signal (what is commonly known as Telecine) and be decoded by most TVs "worth their salt" as the original 1080p24 picture with very little loss in quality. On a codec level, encoding interlaced is typically less compressible so a true P encoded signal would still be of benefit, but it's hardly the end of the world.
Mentioned a politician without starting a flame war? Well done.
Deinterlacing is a type of anti-G SYNC
Anti g sync???? Lol
wut
@@jawknee4088 gsync basically forces every frame to go in its own spot with a smooth transition from frame to frame to elimimate frame tearing. (Poor) deinterlation takes two different frames and forces them together, essentially making the worst screen tear effect possible, combing. Gsync uses extra resources to keep every frame apart, and deinterlacing forces frames together in order to save resources, so they are doing essentially the opposite.
Does the same apply for free sync

@@epicbread1310 Meh, that is barely half of Frank’s TV
CZcams decided to show this 4 years later, and I’m not complaining
I don't understand why 60 half frames would save bandwith opposed to 30 full frames. :O
60i is actually better than 30p in that it has smoother motion for fast moving video. 60p would be better than 60i, but requires twice the bandwidth to broadcast.
TheShonenJumper Because it refreshes faster (since it doesn't have full frames to render).
None of the replies to this comment makes sense , so no it doesn't save bandwidth but gives you a smooth image at the same bandwidth as the jittery one with the one exception of quality loss . But who really cares it's 2018 and we are fighting to get the first 144k monitor then 240k , so on to 1080k
For the same bandwidth you get a smoother motion.
Xistence Studios do you not know the difference between framerate and resulotion
When he said, "Not progressive like car insurance or Bernie Sanders.", that cracked me up.
Well, interlacing was actually also a way to achieve smoother motion (very visible on rolling credits, for example), and the half fields are not from "slightly different frames" - they are straight up from precedent and following frame, so to speak, so deinterlacing that isn't complicated algorithmically at all (as long as we're not talking about standards conversions, where things get really messy, with cadence, frame rate, and scan order).

Thank you Linus. This channel is an easy way for me to catch up on the latest tech. I work in computer repair so this helps a lot.
Annoys me how even in 2019 the BBC STILL deliver shows in 480p,
BBC is European so it probably doesn’t deliver in 480p and I think that BBC is broadcasting in 1080p50 (in UK)
They broadcast in 576i or 1080i. Progressive is not used on UK broadcasts.
"But come on, Linus, this is 2016; Why do we have to sacrifice anything?"
We have to sacrifice thing to gaben.
because it is not 2020
Setting playback to 1.25x makes this as fast as he presents these days. 2023
The interlacing of analog video was not only convenient back then but today it's EXTREMELY convenient that such a standard was in use for video recording because once de-interlaced we can recover 50 or 60 fps video by de-interlacing the frames of that old material, add digital processing to those extracted fields and you get the best quality AND THE BEST FRAMERATE just like that.

+Tiago Luz They don't need to right now, it'll be a huge waste of money because of the very low amount of games that use async anyways.

Asynchronous Compute is NOT an AMD thing.
and for the trolls that talk about nvidia and Async:
maxwell already can perform async-compute, but it highly depends on the developer to utilize it.
Asnccomput is there to utilize the GPU a bit better - well nvidia has always done that by writing their own drivers for big games and making sure they run as efficiently as possible.

Nice to see you on here again Linus.
I didn't come here for this info but sat through the whole thing. Interesting stuff!
so what about the tv channels that are broadcasting 4K (bein sports in the middle east)
yea they offer a hihgh line expensive receiver! Euro 2016 & world cup 2018.
but my questions are:
1- does 4k have an interlaced signal ? or is it only progressive ?
2- if they can broadcast 4k, then i think we can easily have a 1080p 60 fps broadcasted as well, am i right ?
Linus is talking about North America mainly where the infrastructure for this stuff has been there for years and to expensive to change.
Though you are correct the 4k footage you are watching nowadays is in progressive and they do easily also broadcast 1080p.
4K is the resolution it doesn't necessarily denote whether it's interlaced or progressive you can have an interlaced 4K resolution image
Broadcasts have tended to be progressive for 4k, ie 2160p.
When I bought my first LCD back in like 2007 I spent HOURS and HOURS searching for 1080i vs 1080p. In the end I settled on an off brand 32" LCD that was 1080i for $599 and that was CHEAP for that time period. Man how times have changed, now you can buy a 32" 1080p for next to nothing.
Just asking for a reference. How much does it cost though? I'm from India so just wanna know
quality has gone to crap, thats why these TV's are getting cheaper and cheaper
I have tried to understand this for a while, and this is the best explanation Thank you.
I'd love to show this to my high school students, but I can't show teenage boys anything with a guy wearing a shirt that says "holy balls." 😆
Pretty good although some facts are wrong. Basically, TV is recoded at 60fps (ntsc) or 50fps (pal). Each frame is stored in half the horizontal resolution to save space/bandwidth. This means that when we blend two fields to one frame, we are actually merging two pictures takes at different point in time. (we are reducing temporal resolution) This is why any movement will cause combing (those horizontal lines). The result is 30 merged pictures per second instead of 60. For this reason 720p@60 is better than 1080i@60. 1080i@60 is better for fast moving scenes than 1080p@30. However one big reason for choosing 720p@60 over 1080i@60 for sports is because of so many straight horizontal lines that would flicker on TVs with poor quality deinterlacing.
In the clip he shows sum of lines on i, cant be right? should be every other i think
Actually, you never see combing in normal viewing environments. I have a Philips LCD widescreen TV from 2008 that is able to do 720p@60 and 1080i@60 and I don't see ANY! combing at all with the latter
Anyone notice his T-shirt "Holy balls"
You know which way to think,right
Today i was messing with HANDBREAK to convert some old video and I saw deinterlace thing I had no idea what was it thanks for this video :)
Wow man. This is probably the most high quality engineering tutorial video. I was searching for interlace scanning mechanism and stumbled upon this video. Typically, engineering tutorials on youtube are of poor audio/video quality.
It's also somewhat wrong, as it gives the impression that the consecutive half-frames form a full-frame. That's not the case. A 60i signal is a 60fps video with every other line skipped, alternating between even and odd. The missing lines are completely discarded. There is never a full-frame in an interlaced signal, each half-frame is created at a different point in time.
And what is with IPTV? Is there interlacing too?
i would like to know too
I think that no, we have cable and also IPTV from the same provider - cable channels are mostly delivered in 576i50 and 1080i50, but the same channels, but via IPTV are delivered mostly in 576p25 and 720p50.
IPTV is delayed and rubbish, tends to be progressive

nanopulga098
But this video doesn't have a 4k option
They are in USA so I don’t think that they’ll shoot at 50p
@Lucas Silva 60fps also doesn’t look good unless it’s displayed on 60Hz or 120Hz xdd
25/24 FPS is used in films and tv and is sufficient.

why does old consoles like nes/snes/genesis/ps1 all look better on interlaced crt tvs vs newer progressive screens (small lcdtvs 16"-21")?
Because that's what they were made for
Because most TVs have poor quality deinterlacers.
because they don't scale appropriately to hd resolutions?
+Brett Kessner consoles output at 240p, a whole different standard that cheaply made TV scalers either can't handle well or completely misinterpret as 480i

I understand the 480i and 576i signals as they were born so long ago that there were really not much alternatives, but the 1080i standard should never ever been created. Deinterlacing is never the same as an originally progressive video and also it is bad for editing and playing videos.
On the time that HD resolutions arrived if for some reason still there was any bandwidth issue preventing 1080p60 to be used (which probably wasn't, they just wanted to fit lots and lots of channels more on the satellite links with low bandwidth), 720p60 should have been chosen as a default instead.
….and it is what they used and still use prob over 50% anyway, still… HAH, TRUE that / (ON) This BROSKi … ......
Interlaced is bad for playing videos, really? I've got a bunch of family footage from the 2000s that was filmed on different cameras, etc - the interlaced videos, when deinterlaced, look like they're going at 60 fps, they blow the competition out of the water. If I could choose between double the percieved fps at the cost of not being able to get good still frames when pausing, I know what I'd pick.
@@andreivaughn1468 interlacing is bad when all our displays are progressive nowadays. If possible, everything should be at least 60 progressive frames. I also have lots of VHS footage from the 90's and 2000's. Indeed when properly deinterlaced they look good and it was needed back then as there was no pratical way of recording 480p60. When high definition standards were conceived, there were 60p options, so 1080i shouldn't exist. 720p60 is better than 1080i for editing, recording, playing...
@@arthurand1006 I've used progressive displays all my life... I am not that old, but what I am saying is...clearly there was an era where 60 progressive fps was not feasible, and in that era, the "faux" 60 fps that could be gained by using interlacing looks better than standard 30 progressive fps. To my eyes anyways!
I'm not saying 60 interlaced frames is better than 60 progressive frames, I am just saying 60 interlaced frames seems to take up the same storage space as 30 progressive ones AND looks better.
