Question / Help Doubt about bitrate

[tiba]

Hello guys, im new on OBS.

I used xsplit from a long time ( pay to use ) and now im changed to OBS.

My main question is the following.
In xsplit, I left 2400 bitrate for video and 96 for audio bitrate
When I started it was just the transmission bitrate of 2500 (I have 3mb upload ie if you spend that amount which I put my ping is affected within the game)
However in OBS can not limit it, but now I put it always passes and arrive at 2800 ~ 3000
How do I limit it?

And another point is this, I think my machine is powerful enough to transmit 1080p at 30 fps with the preset "FAST"
But I'm not sure, I would ask for the recommended settings for my computer

You could do with whom they had a autodetec and to test what would be the best option for each machine right?

Follow my config:


I7 4770k@4.4GHZ - H100i - 16GB 1866MHz DOMINATOR PLATINUM - ASUS MAXIMUS VI HERO - POWERCOLOR 7970 3GB - AX860 PLATINUM

Depending on your game, you may be able to do Fast preset at 1080p30. If the game is very light on CPU usage.

You might also try Quicksync. The Quicksync encode on the Haswell line is rather good quality at those bitrates, significantly improved over Ivy / Sandy Bridge.

By its nature, H.264 encoding has a target bitrate, not an exact bitrate, but you can constrain the bitrate fluctuations by lowering the buffer size. This will reduce quality the more you reduce the buffer, similar but less severe to lowering the bitrate itself. I do this, and stream at 3000 bitrate and 2000 buffer. You might try 2400 bitrate and 1600 buffer, for example. Play around with it until you find what works.

If all else fails, post a log file.

Boildown, how i enable Quicksync? No have this function on my OBS.

still going to 2700 and my ping grow up...
like a said, i had 3mb upload, if i used more than 2.6mb my ping grow than 20~30 to 100~120

look

No one? helps?

Check "use custom buffer size". To use Quicksync, you probably have to enable it on your motherboard, install the driver, and attach the video port on your motherboard to your monitor's alternate input (even though you don't use it). I'm not exactly sure TBH, a forum search here should reveal the answer.
