Reading inspector stats

[matizzrawr]

Hi. Recently I noticed that during more action the stream goes full pixels extravaganze. It's... rather bad, to say the least. Especially if comparing with other streams that use same resolution and play same games - 720p60 to be exact. I've checked my setup, did some configuration changes both in OBS and to my network. Inspector of course says that everything is fine, no adjustments needed, but, I to be fair have no idea how to read the bitrate scale. I know there is a whole boadcast health post from twitch itself, but it's still a little bit confusing for me.
Could someone take a look at this graph here, which is a 10 minute test after the adjustments I did around, and tell me if this is good or bad and I should go full panic mode? I'm adding the OBS log too. Would be much appreciated!

(Side note. I analyzed one test log previously before doing adjustments to my network settings on the rig, and it have definitely more warnings then this one here now - mostly unmatched sound settings which I corrected. Still, if someone more tech-savvy with OBS/streaming/network would take a look I would greatly appreciated you!)

Best regards!

Twitch inspector is a Twitch app. You should contact Twitch support.
Anyway, in the image looks fine.

As of the log file from OBS, it only shows you need to update windows.
Is your display 720p? It's strange as normally it's 1080p

10:37:02.494: base resolution: 1280x720

Probaly you'll want to run the Auto-configuration Wizard (tools menu), aply the settings it gives (do not change it), restart OBS and test it as is. If it goes well, keep it this way.
To better measure your internet connection against twitch servers you can use this tool:

TwitchTest | r1ch.net

Test your upload bandwidth and connection quality to Twitch

r1ch.net

Anything bellow 90 quality is bad and probably reflects an issue within yout ISP

Thanks for the reply!
Yeah I didn't know if going to support right away is a good call since, I kinda don't have an issue? It's more of lack of knowledge really. Cause they show all those like examples of instability in Broadcast Health, but then there is some red area, and is that the problem? The read area? Or the whole graph shows that connection is bad?
Thanks for looking tho, I do tend to get a bit jumpy in terms of tech so I wanted to be sure and ask :v
As for the resolution. So, very long time ago, someone sold me a trick they were using, which is setting both original resolution to the one in which you want to stream, instead of putting your native and then downscale. I used that for... quite some time now to be fair. It's to pretty much omit the need for downscale and make room for resources to go to other stuff? In lay terms, I don't remember the full explanation, sorry. But for a noob like me getting rid of downscaling sounded fine.
I could probably push for 1080p streaming - ryzen 5 3600 x RTX 3060 12Gb with upload 40mb - but never felt the need, plus I heard 720p is easier for viewers, plus the dreaded pixelization scares me. Not that it does not happen from time to time apparently, hence my investigation.

I actually ran one more test. The one above is with MTU 1462 which was the highest without dropped packets - read some guide that changing MTU helps with bitrate overall. But then read that one shouldn't really mess with it, and that modern systems and routers have ways to deal with the default settings anyway, so I got back to 1500, which was stock setting, so to speak. This is the graph:

It's also to the best possible server after running TwitchTest app you've mentioned, a server with 100Q - 19ms - 10k+ bitrate
It kinda looks more stable than previous one. If it doesn't show any red points like the examples from Twitch itself, is it good and stable then?
One more question - sorry! - I once heard that if the bitrate fluctuates a lot, it's actually a good practice to set it in OBS to the Average shows in Inspector, to make it more stable, is that a thing or a myth?

Unless you know exactly what you're doing, don't mess with settings within windows and it's drivers.
The MTU 1462 it's an old thing back from when we have ADSL connections, wich where far slower than current connections.

If it works, don't brake it.

Base resolution should always be the display resolution.
Output resolution is the one you aim to stream to. Unless you have issues with the network or an old computer that can't handle it, you're safe setting it at the same resolution of the base resolution, this way you avoid the extra scaling process saving resources.
If your display is 1080p, simple set both at 1080p

Don't overthink it. Keep it simple.

 

[matizzrawr]

I see. I'll give it a go then and see how 1080p works maybe.
How about the graph with default MTU, are those jumps worry worthy or nah and if it says stable it's stable and leave it?

Don't overthink it. Keep it simple.

 

[matizzrawr]

Yeah, you're right :v maybe I'll see what the OBS itself says about the possible settings for my machine and go from there. I used to approach all this much simpler damnit :v
Thanks for your time sir! For what it's worth I really appreciate it!
