Hi Guys,

I will try to explain it quickly. I am a non-partnered twitch user.
after a yearly pause, I started again to stream but my stream quality is more worse then before.

Now i use 2 machines(i think thats the reason of the bad quality) a desktop and a gaming laptop. below the specs.

Gaming machine:
i7 7700K
GeForce GTX 1080 GameRock 8gb
Corsair Vengeance LPX DDR4 16GB

Streaming Machine:
Asus Rog G751JY
i74860HQ
NVidia GF GTX 980M
8GB Ram

My upload speed is 6mb

I think more specs are not needed.

I was trying to use an Avermedia LGP 310 capture card, but the quality of the stream was pixelized.

Today i tried to use the non capture card method with the NDI plugin but the quality of my stream is still poor.

I'll tried different bitrates and presets but everything gets laggy or is still in bad quality...

I dont want to stream in 1080p.
720p 30fps is ok for my viewers.

Do you have any suggestions how could i exceed the quality of my stream? What settings would you use on my machines? What kind of connection avermedia or the ndi plugin?

If it would be possible, i would love to go ahead with the NDI plugin..

Hope for some good news...

All the best,
Konrad

We'll need logs from the streaming PC to know for sure what's going on.

Please post a link to a clean log file. To make a clean log file, first restart OBS, then start your stream/recording for ~30 seconds and stop it again. Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc. When you're done select Help > Log Files > Upload Current Log File. Copy the URL and paste it here.

I just tried to record a video as sample and the quality of the recorded video is the same as the stream quality. So i guess the problem is not really the stream just the OBS game capture quality. What would you suggest guys?

Im out of any ideas..

Your CPU is still overloaded on your laptop, although (as Fenrir asked) you only streamed for a few seconds. But we really need a longer stream to really know if that was an aberration or not. Try a five minute or longer stream of high action video, and post that log file. This is why I always ask for five minutes... 30 seconds can tell us if your config is horrible or not, but the encoding stats will be skewed by startup costs in a video that short.

Make sure Windows 10 Game Mode is turned off. Try also adding a custom x264 command of "threads=10" if you're using the Advanced encoding option.

You mentioned streaming, but your log is only of recording. If you intend to record, use a higher bitrate, or CRF mode. If you intend to stream, then run your tests while streaming. Which brings me to my next point, if your upload speed is 6Mbps then 5Mbps might be too much for it. The logs will tell though if you test it.

Hello,

I did a nice setup which made my quality look better but a few minutes ago, on the stream when i started to play counter strike GO - OBS started to "LAG" it was almost like 5 fps stream... Here are the LOGS

I really hope you can help me with this.
My CPU is overloaded on my laptop? Usually Everything is closed, only OBS + Deep bot / youtube for music are on.

Everything performance wise looked fine in that last log, save some dropped frames due to connection:

20:58:23.501: Output 'adv_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 773 (2.2%)

So Maybe the NDI plugin is not that good for dual pc setup? I mean, the quality looks really good but when there is a lot action or faster movement ingame, the stream looks like it would get fps drops every 5 secs..

NDI should be just fine for that. If the preview looks good in OBS, something else is going on.

I took another look and noticed that you have these two values backwards:

20:37:31.560: base resolution: 1280x720
20:37:31.560: output resolution: 1920x1080

The BASE should be 1080p, and your output should be 720p. Try flipping those in Settings -> Video and see if that helps.

There are also big FPS drops on the preview of OBS (streaming machine).

I tried several vartiations, but everything is still the same. The only thing what came in my mind is to...recover my windows on the streaming PC. I didnt do it since i got this machine so for around 2 years, and the last half year it was not used often.

Addionally i noticed that i have some problems with the Battery in my laptop novadays (I think the bat is dead...). I already contacted ASUS support about this and they should pick up my machine next week.

Yeah but now i try to re-install windows and let's hope it can fix the issue cause as you said, it looks that its not OBS fault..

You're using NDI with a wireless connection, that sounds like a bad time waiting to happen to me. Use a wired connection.
