Interlaced vs. Progressive Scan - 1080i vs. 1080p 

Linus: ‘come on guys its 2016’ Me: *laughs in 2021*

When he said "cmon guys, it's 2016" I realised this is year 2020 EDIT: It’s 2024 now and I am still getting likes on this comment….crazy imo

Lol I thought p stood for pixel

RU-vid Recommended: here Me: *watches* Linus: "Its 2016" Me: *visible confusion*

UC i always thought the p in 1080p stands for "pixels"

Dat sunburn.

"the problem is bandwith" >video stops to try and buffer for 2 minutes yeah you're god damn right

*_2016:_* 720p 60fps *_2020_* 1440p 240fps

I can't wait until the day interlacing finally dies

If only Linus uploaded in 1080p60...

_"Oh come on, Linus. This is 2016."_ Simpler times. 😔

In 2010 we got a 50 inch 1080p TV and we were really excited to open it just to find out most channels are ONLY in 576i

I was watching this and learning only to hear him say "it's 2016!" Having my life flash before my eyes

0:35 That picture of Bernie Sanders was taken in my highschool gym. 😂😂

Linus: "it's 2016" Damn has it really been that long?

You know you're watching a Canadian channel when the first Sport that Linus could think of was Ice Hockey :D

That P stands for Pascal. GTX 1080P for 4K.

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.

in 2023 and the bbc’s live broadcast service is still in 1080i (some channels 4K60)

Mentioned a politician without starting a flame war? Well done.

Why did films skip 2560x1440.

Deinterlacing is a type of anti-G SYNC

RU-vid decided to show this 4 years later, and I’m not complaining

When he said, "Not progressive like car insurance or Bernie Sanders.", that cracked me up.

Linus, I think you are about 10 years late with this one...

I don't understand why 60 half frames would save bandwith opposed to 30 full frames. :O

Me an intellectual: p = pixels i = inch

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).

Annoys me how even in 2019 the BBC STILL deliver shows in 480p,

Setting playback to 1.25x makes this as fast as he presents these days. 2023

In my 17 years of using youtube, this is the first video that does not have a single dislike. Congratulations!!!! great video

Why did I think the title was: *“1080 vs 1080ti”*

2020: 8k over antennas Me: excuse me WTF?

"But come on, Linus, this is 2016; Why do we have to sacrifice anything?"

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.

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.

heh, right when he said 720p my video quality dropped to 360p

Yet another reason to join/continue the PC master race, thnx Linus

You give really great advice and explanations but dude, take a chill pill. I'm still processing the intro when you're wrapping up. Gold medal for most words per second! For realsies though keep up the good work.

Makes 2016 video on tech that's been around and explained over 10+ years ago. Way to go.

3:44 come on linus this is 2016 me looking up when this video upload.

3:43 I say " Come on Linus THIS IS 2020 WHY DO WE HAVE TO SACRIFICE ANYTHING"

Some of you seem very shook that videos from the past exist and it's lovely.

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." 😆

Linus: "Its 2016" Me: whaaaaat

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.

"Come on Linus, this is 2016!!" Watching in 2022, wish I could go back then once again

AND my TV experience is solidly spoiled. Thanks LINUS.

I love the way he said "come on linus its 2016 why do we have to sacrifice anything!" Like its 2021 now and we have sacrificed a lot over this virus...

"we won't get 1080p any time soon" four years later - 8k with 64 times as many pixels

"Pee in the 1080p, makes life more easier" - Confucius

your video brought back my engineering days , electronics engineering rockss😎

Shiny happy electronics👌😂 Great video Linus!

Could you please film and edit in 50 or 60 fps. RU-vid supports it now and it was really apparent in this video with Linus's many fast hand gestures.

You know i thought my eyes were fucking with me when i was watching 1080i videos compared to 1080p on my computer. I legit thought my eyes were broken and im the only one who could see those lines during movement. I didnt see these kind of videos since 2 years ago. This cleared up everything and i no longer think my eyes are fucked up. Thanks man.

Time ran so quickly 2021 has come

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.

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.

Every time my mind wanders and I think of a technical question. I always end up here with You Linus. Cheers for being you Subscribed.

I always thought 1080i looks less jagged with fast motion and wide panning due the motion blur that interlacing introduces...

AMD Asynchronous Compute as fast as possible

1080p generally produces a sharper image than 1080i, and often with less motion blur on an LCD TV. For this reason, I find 1080p better for gaming.

I take exception with your use of the word frame in regards to 1080i. With 1080i, each FRAME is composed of 2 FIELDS displayed one after the other, referred to as upper and lower fields (odd lines or even lines)

Man we have come a long ways in 4 years.

Anyone notice his T-shirt "Holy balls" You know which way to think,right

Wait so p doesn't mean pixel?

I feel like these videos have become alot... calmer

Bravo Linus. I am currently working with video Quality Control and have to deal with those issues daily. Keep up the good work!

why does old consoles like nes/snes/genesis/ps1 all look better on interlaced crt tvs vs newer progressive screens (small lcdtvs 16"-21")?

And what is with IPTV? Is there interlacing too?

Bourgeoisie is a noun. If you're trying to use it as an adjective, you want Bourgeois.

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 :)

"or Bernie Sanders" xD I laughed but also cried a little bit.....rip. Heros never die, they only re-spawn.

2:46 The Aristocrats! by Gilbert Gottfried !!!

"Come on linus! This is 2016" *laughs in 2023*

"Come on it's 2016" Me, in 2022: *starts crying*

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 ?

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.

2016 Linus was so cute, lol.

When he said it's 2016 I just realized im living in 2021

I always thought the P in 1080p stood for 1080 pixels

3:43 wait wait wait... HOLD ON let me check

Fun fact, in France, the poorest video quality on TV is on Fance 3 channel, wich is one of the "France TV" channels that are public service. I have never seen a TV that could deinterlace the signal correctly. Other channels don't have this problem (yet I don't know if they are 1080i or 1080p but FR3 is 720i). I think the reason is that, while the signal being 720i, It's the channel that handle most data on the broadcast sign, as we have localised FR3 channels, almost one for each region, all sent to France TV, then to the ISPs or TNT antennas. So they might need some more bandwith than other channels. And in some cases, like France 3 Poitou-Charentes, they broadcast in 480p upscaled.

". .. this is 2016!" *Laughs in 4K in 2023*

Me: laughs in 2019

"it's 2016" 😭

here in 2022 and this video is like fine aged wine

Nice to see you on here again Linus.

damn, when u say its 2016 im almost cry =(

"Come on Linus, this is 2016!" wat

RIP TunnelBear

What I've noticed is that most cable companies in the US almost always support progressive scanning. DirecTV didn't however from what I remember, they mainly used interlaced, you had to pay for a progressive signal. Spectrum lets you choose what you want your resolution to be, whether it be 480i, 480p, 720i, 720p, 1080i, or 1080p. But for my antenna that I'm using most channels use 480i and almost never drop in signal. But some local channels like channel 9 (ABC) use 720p but channel 36 (NBC) and channel 3 (CBS) use 1080i. I've noticed that sometimes because of this, lag can be terrible if it's raining or even if it's windy. Meanwhile channels that are using a lower resolution or a progressive signal, are more clear and reliable, even during a heavy storm. This is why I'm glad my antenna doesn't need it's own power supply because I can just plug my TV into my UPS and watch TV if the power is out.

I still use my CRT Sony Trinitron from 1987 (480i, I think?) lol...

Liked just for the Bernie reference

*Cries with Sky+HD.*

Dude, you might be the reason I pass my Digital Television course at Uni.

My Internet is hell slow

He is talking about 720p and 1080i And I am watching this video in 1080p🥲

Dear youtube commenters. 1080p, 1440p etc, are digital television formats, not display resolutions. The word you're looking for is "Full HD" or FHD (1920x1080) or QHD (2560x1440)

I didn't come here for this info but sat through the whole thing. Interesting stuff!
