YouTube Upload Quality Issue

Dicehunter · 4 Dec 2015 at 14:25

So I recorded a little gameplay segment of Battlefront for a friend who's a big star wars fan, Uploaded it and in the fast moving segments the video starts to look a tad pixelated but the video before it's uploaded looks great.

I've tried uploading in 10Mb/s, 20Mb/s, 30mb/s, 40Mb/s and 50Mb/s video quality and nothing helps.

This is the video, You'll notice when the action speeds up the video becomes slightly pixelated but doesn't happen with the locally stored video -

What video codec & container did you use? H.264 & MP4?

Did you compress it before you uploaded to youtube?

Also, what recording / editing software?

Sometimes, I find it varies from game to game, e.g. the grass in S.T.A.L.K.E.R. - you haven't seen pixelated until you've seen that.

Are you following those guidelines?

Sorry forgot to mention that.

I'm recording using Shadowplay and editing in Adobe Premier, Rendering in MP4 with an audio quality of 48KHz and video quality of 20Mb/s but I've also tried up to 50Mb/s which didn't make a differenc.

I've also tried uploading the raw file which made no difference either in the fast sections of gameplay.

I think you're just seeing the limitations of YouTube to be honest. They're only going to want to consume enough network capacity to deliver "good enough" quality.

Have you tried Vimeo?

Are other recordings like it, or just this one?

I don't know if it will help much, but I recently saw these videos of Gopher's (whom I tend to regard as having some of the best quality I've seen), so maybe take a look at this :

He seems to use AVI / MP4, but what with AVI being so disk space hungry, I've been sticking to H.264.

I'll post some of my settings shortly, as I've recently started using Adobe Premiere Pro, too (free trial).

I don't know if I have the best settings, but so far I've been using these :

Why are you using constant bitrate?

Cheers, I'll have a look.

Edit : Two passes doesn't make much, if any difference imo. Maybe it will vary from title to title.

It's the bitrate for 1080p. Apparently in 4K the bitrate is much better (in terms of how much bitrate is allowed for 1080p, 4K being 4x the size of 1080p has more than 4x the amount of bitrate).

Try applying a bit of a sharpening filter on it and uploading it. See if that makes a difference.

Even after YouTube converts and they say there 1080p they can take a few hours to become max quality

The video you posted looks fine to me

Well I'm only uploading in 1080P 60FPS but as I said I've tried varying bit rates with no success.

Watch again and you'll notice at the edges when the action gets fast you'll see quite harsh pixelation.

You could upload it uncompressed, and it won't make a difference because YouTube is compressing it to the bitrate it has set for different streams.

For that set bitrate at 1080p60 it can't keep the image quality at the amount of motion in that video, which is why it'll always appear blocky and horrible during fast movement.

I uploaded some test footage straight from shadowplay and it still shows pixelation, Guess YouTube need to do something on their end in the future.
