Question / Help Stream fuzzy

[Icycoldd]

Hey, after receiving an internet upgrade today (50 mbps down/10 mbps up) I tried to stream. Everything was fine when I was standing still on my screen but when action started (MMO) the screen gets really fuzzy and seems like there's maybe 8 pixels on the screen.

I googled and found some solutions from these forums. They recommended to turn on CBR, don't resolution downscale (I was downscaling to 720p), etc. I turned on CBR, set my resolution to it's default 1920x1080 and still get a really fuzzy stream during movement.

If you want to see what I'm talking about or how bad it is see here starting at 6:48:

1500 is way too low bitrate for a 1080p stream, you really need around 3000 to make it look decent. The max bitrate for Twitch is 3500, but the problem is that a decent number of people will not be able to watch that lagfree. It just depends what you want out of your stream. If you want an average looking stream that people can watch downscale to 720p and use 2000 bitrate.

Which downscale filter do I use? It's currently at bilinear.

Lanczos is best quality. And yes, for 1500kbps you can pull off a (mostly) decent-looking 720p@30fps stream.

Wow, what a difference. I'm using quality balance 8 only as well. Not sure if I can do 10 but this is a lot better I really just wanted to eliminate the fuzz.

Quality balance is irrelevant when streaming with CBR.

I was going to make a new thread, but considering this one isn' too old:

If I want to stream BF4 with this system: i5-3570k GTX 670 FTW and 6GB of ram, what kind of OBS setting should I run?

 

[Krazy]

You should absolutely use QuickSync. BF4 is a very demanding game, you likely won't have spare CPU resources to stream and play smoothly without using the QSV encoder. You may have to drop to 480p if you can only use 1500 or so bitrate as Ivy Bridge QuickSync isn't as good as veryfast preset encoding quality.

 

[Icycoldd]

Where can I get QSV?

 

[FerretBomb]

QuickSync Video (QSV) is supported on certain Intel CPU/Mobo combos. You may have to enable it in the BIOS. There should be a checkbox in the OBS settings to enable its use, if your CPU/Mobo are compatible and it is enabled in the BIOS.

 

[Icycoldd]

Alright, when I enable it will that have an effect on other games I stream which are not as demanding such as an MMO?

 

[FerretBomb]

Yes. QSV encoding is a bit worse than the Veryfast preset, but it essentially becomes 'free' on the CPU side, or effectively enough.

You can set up a QSV preset profile, and a non-QSV profile though. Just remember, create the profile FIRST, then change the options while the profile is active. Not the other way around. You'll have to stop the stream to switch between them, but so long as you activate the one for the game you plan to be playing for that day before you go live, it should not be an issue.
