Hello Guys,

I would like to stream some LoL games..
I only have 0,85 in upload but i found out that a lot of people stream a with a decent quality.
I mean, they stream lol games without blurry or stuff like that.

http://www.twitch.tv/muladdino/b/473050076 That's a video of my latest stream. It's blurry when i move the camera.
I need some help for find the best settings for me.

my spec :

i5 750 2.67 ghz
ram 4gb
graphic card: ati radeon 4500 series (this isn't so good but never gave me problems at all with lol..)

(I can also buy 4gb more ram if needed..)

The settings that i use now are those:

Encoding: flagged use cbr, enable cdr padding,
quality 3
max bitrate 280, buff size 180
Audio : acc 96 bit

Video: Resolution : 960 x 540 30 fps
x264 cpu preset: very fast
x264 econding profile: high

Can you tell me how to stream with a "decent" quality in a 480 p ? I don't wan't a HD stream but a watchable stream ^^
Thank you

Reduce to 25 or 20 fps and try to lower the cpu preset (choose a "slower" one).
Not sure if you can go all the way down to medium with this CPU tho, but a slower preset reduces the block artifacts a bit.

My first thought is that your video card and CPU could both be holding you back. Both are older and OBS uses them both, as does LoL. You may be able to do one or the other fine, but both at the same time could be a problem, especially if you want to use a higher quality (slower) preset.

P.s. post a log file.

downscale to 480p use 25 fps bitrate 500 and uncheck custom buffer so the buffer is the same as your bitrate and see how your ping goes

What about my bitrate? 300 is low.. but if i get it to 500, i start to lagg in game..
Anyways with this settings :
bitrate 400
buff size 300
aac 96bit
use cbr on
enable cbr on

resolution 1280x720 downscale 1.75 bilinear,
30 fps

preset : medium

i have a good quality stream but the ping gets to 100 and spike 80-120 from a stable 60..

If you lag in-game, you need to determine if its your computer lagging or your connection that's lagging you. If its your connection, you have little choice but to lower your bitrate. But since you haven't posted a log file, we have no way of telling you which it might be. Also, use Very Fast, your CPU/GPU cannot handle Medium.

Drop your framerate to 20-25. Drop your AAC bitrate; 96kbps is good, but you honestly don't have the bandwidth to spare to spend almost an extra 100kbps on your audio, on top of the video stream. Try dropping to 48kbps and see if it will work well.

You need more upstream bandwidth, is the short version. See if your ISP offers a package with a faster upstream, and consider switching to it.

at some point you gotta agree that you need some sort of uploadspeed... if you cant literally got nothing to spare for streaming you are not really supposed to stream at this point :(

Click to expand...

1) Set your audio devices to 44100 instead of 48000. Don't make OBS do extra work.
2) Increase your downscale to lower your resolution a bit more.
3) Very important: Use Very Fast preset, not anything else. Right now you have it on Slower, which is a Really Bad Idea.
4) You're streaming to Twitch, which means you need to turn CFR (Constant Frame Rate) to "ON" i.e. "YES", not "off" i.e. "no".

Do that, stream with it for at least a couple minutes, then report back here with your thoughts on the quality and post a new log file.
