Youtube pixelation?

[Danny Hays]

I took a screen shot of your original and used these settings and this is what a 5 sec you tube vid looks like for me.


In the render settings, in the project tab, I set render quality to best.

Hello Danny,

thanks a lot for your input. I took a look and the only difference in our settings is that you selected CBR at 50mbps and 32bit (full range) quality colors. I’m going to try the CBR at 50mbps as well and at the same time I’ll try to select 32bit (video levels) color quality. It seems as if the colors with the full range quality are a bit too dark.

Anyway I’ll write back when I’m done with the testing, I’m in the process of doing it.

Once again, thanks a lot for reply!

Ok Danny,

I just tried the same as you did with the screenshot. Just to be sure if it’s not something with my pc etc.

The result is the same. Crystal clear quality… -> https://www.youtube.com/watch?v=9v0p-qG1zvc

that means, what destroys the quality is the movement. I’ve tried smart resample (which I really hate) and no resample, it seems to be a problem when using both of them.

Did you upload a video to YouTube using the settings I used? If you did, can you post a link for me to see?

Yes I did. Except for the 32-bit full color, Youtube didn’t want to process the video using that option.

So I just chose 32-bit video levels

I hope it’s just not me, but the quality is still terrible… you can immediately see the pixeling on the trees.

That’s weird. YouTube did it for me with those settings,,,,?? I can’t see your video unless you set it to listed or public. Private means only logging in as you lets it be viewed.

Gosh.. sorry 😀 I swear I set it as Unlisted, apparently not 🙂

You should see it now.

I see what you mean. Does it look good after the Vegas render, before YouTube encodes it? That’s a pretty small clip. Anyway you can dropbox it to me, or even a one second sample so I can experiment with it? A 1 sec. clip may be small enough to email it to me. danhays2004@yahoo.com

It looks absolutely amazing when I watch it from the PC. But once Youtube encodes it, this is the result.

Yes sure I can, I’m just going to sleep so I’ll get it for you tomorrow!

Thanks once again for your replies.

Have a nice day!

If what you render from Vegas looks good on playback and the Youtube result does not, then there is NOTHING you can do.

Youtube re-encodes everything uploaded to their own spec. Their spec is very low bitrate and very often game material does not compress well enough to maintain a certain visual quality. This has nothing to do with some magic encoding setting. It is entirely dependent on exactly what is going on in the video at at every instant in time.

Again, if your encode looks good, then how is it possible that giving Youtube something different can possible help. The loss of quality is entirely from the Youtube re-encode. If someone elses game video looks better then the the specific sequence of frames in their video just compressed better into the low Youtube bitrate than yours did.
