Adding black bars to get 16x9 aspect ratio

[Knocks]

If you don't believe that youtube applies different compression schemes on SD, HD and UHD just lighten up yourself by googling it, or ask the coding experts here they will clue you up.

So this is the first time someone actually formulated the essence of this argument in this thread. People can't read your thoughts, why get mad when people don't understand them?

And yet my point remains valid. I asked for proof of the claim that Google encodes 480p videos at lower "quality" (which, I assume, means fewer bits per pixel, crudely speaking, or perhaps using an inferior codec or algorithm) compared to how it processes HD videos. In response, you linked an article that does not address that issue at all. If you point to an article written by a competent person that's well-written and backed up by sources, everybody will win. I'll have something to read and you'll have nothing to argue about.

The article I posted just an announcement that 720p has been added to SD list in response to the poster who posted numbers of different resolution thinking 720p is HD, it's not what you think. But if this doesn't ring a bell to you then why youtube have classification by resolution then? explain that to me. But instead of trying to argue to disbelieve, do some tests and see for yourself, that kb per pixel means nothing, I see the quality by my eyes and I see the excessive compression on 480p, I even posted about it here before -see link below- and I did numerous tests on different sources and all checked out, Now show me your samples that prove otherwise:

The linked "article" was poor to say the least. It may nevertheless in some way reflect internal thinking at Youtube (all devices/networks can play now play 480p, most available content has at least 720p resolution, with 1080p being the real HD resolution ?).

Google isn't providing free video hosting out of the goodness of their heart, it's a business. Check the terms of service: I doubt they guarantee encoding bitrate.
All online video services use bitrate-resolution pairs (referred to as a bitrate ladder) and subject to change, nothing unusual there. If the service doesn't meet your needs don't use it or complain to youtube (good luck with that).

After resizing to 1080p I'm very pleased with the service, Thanks to the knowledgeable members here.

If you wonder why I need the padding, it's to prevent YouTube from downgrading my uploads to 360p. If a video is even one line shorter than 480, YouTube no longer considers it 480p, so padding with black bars is a workaround to keep whatever quality the video had.

Why not just resize it to 480p? So what if the width increases a little?

@Knocks If your content is natively 16/9, you should avoid unecessary padding and just upscale to 480p. It's a fair assumption that most users will upscale your video at playback to at least 480p.

@dellsam34 Expect some negative user responses to upscaled 1080p videos obtained from SD sources, unless the quality of the result approaches the standard for native HD (which seems unlikely).

Well, 1) “SD” is just a meaningless buzzword, actually YouTube

No.
SD = standard definition, and max SD is 720x486/768x576 (but digital, and analog equivalencies).
Where has Youtube referred (and wrong, if so) to anything greater than 480i/p as "SD"?

“HD”

Technically, quotes isn't unreasonable here.
HD is "high definition", and no resolution is matched to it. So 720, 1080, 4K, 8K, WTFK ... all "high" compared to "standard".
More myopia in jargon. Welcome to video.
They added "ultra" at some point, to refer to anything that was (arbitrarily) over 1080p.
At some point, we'll have Super Ultra HD. (You think I'm joking?)

What I mean is : it's totally arbitrary that those particular resolutions were (retroactively) labeled as “standard”, and resolutions above 1279x719 (or 1919x1079 since 1280x720 is sometimes designated as “HD ready”, whatever that's supposed to mean) were marketed as “high” definition. There may be historical explanations, but it's still arbitrary, it has no character of necessity — and thus no character of perenniality.
And apparently (I learned about it here) YouTube has decided overnight (without bothering to tell Tchaikovsky the news, or anyone for that matter) that videos with a “720p” resolution would now no longer be labeled as “HD”, so even denominations which seem well established can have their meaning changed over time. (I still don't know how they now label a video that is for instance 1920x800 — is it “HD” because of the 1920 width, or not-HD-after-all because of the 800 height ?)
And if I'm not mistaken, 1024x576 is still considered “SD”, although the height is superior to a “HD” or “““HD ready””” (triple quotes aren't unreasonable here) video with a 1280x528 resolution (A.R. 2.40:1, just looking at one right now, happens to be the movie Gattaca).

Technically, quotes isn't unreasonable here.

Arbitrarily — that's the operative word.

Unfortunately, no, very serious people in fancy suits are probably talking about it right now in a well heated room, while I'm freezing over here and none of my whimsically convoluted ideas will ever contribute to the Technological Future of Society...
(“You think I'm joking?” reminds me of two quite frightening yet also quite hilarious cinematic scenes involving Joe Pesci and a pencil, or Arnold Schwarzenegger shaking a woman to death in his legendary early performance as Joseph Schmidt in The streets of San Francisco... That scene from the beginning of the episode is relatively well known on teh Internetz for its outstanding memetic quality, I shared another one at the end which might be even more funnierer. It's all about progressive resistance — but for some odd reason he doesn't mention anything about interlaced resistance.)

[butterw]

For landscape videos with AR different from 16/9, "720p" format typically refers to width=1280.
For vertical/portrait mode videos, "1080p" format likely refers to height=1080.

No, I'm not seeking HD quality, just less compression from youtube?.

That clip has severe compression artifacts, Try an upscaling test to 1080p and see how much you can get away with, You will be surprised.

You left out Enhanced Definition.

Where I live, I'm pretty sure 576p was legally considered (by whoever sets the broadcasting rules) to be HD in the early days of digital.

I have no idea if that's still the case. I never watch free-to-air TV.
