Question / Help Can I get a better stream?

[pierpa91]

Hi guys, I'm trying different settings for my stream, but maybe somebody here can tell me more and how obtain a better stream.

I use my iMac Late 2012 27'', with Windows 7 64bit installed with Bootcamp.

This my computer specs:
Processor: 3.2GHz quad-core Intel Core i5 processor (Turbo Boost up to 3.6GHz) with 6MB L3 cach
RAM: 8GB (two 4GB) of 1600MHz DDR3 memory; four user-accessible SO-DIMM slots
GPU: 3.2GHz NVIDIA GeForce GTX 675MX graphics processor with 1GB of GDDR5 memory

My internet test:

I have a PS3 and an Elgato Game Capture. I set the Elgato at 720p 60fps.
Now, my OBS settings:

Encoding

Video:
Use CBR: enabled;
CBR padding: enabled;
Quality Balance: 8;
Bitrate: 2800 kb/s;
Buffer Size: 3200 kbit;

Audio
Codec: AAC;
Bitrate: 160;
Format: 48khz stereo;

Video
Base Resolution (Custom): None (1280x720)
FPS: 60;

Advanced
Use Multithreaded Optimizations: Enabled;
Priority Class: High;
Scene Buffering Time: 400;
x264 CPU Preset: veryfast;
x264 Encoding Profile: high;
Keyframe Interval: 2 (for Twitch);
Use CFR: enabled;
Custom x264 Encoder Settings: opencl=true;

Your audio bitrate is too high, turn it down to 128. Also set your audio devices (console), audio inputs (sound card line in or whatever Elgato uses) and OBS all to 44100 for most efficient use of your resources (or all to 48000, they should all be the same, but in theory 44100 is best of all).

Don't exceed your bitrate with your buffer size. So if you are streaming at 2800 bitrate, don't have your buffer at more than 2800. This isn't a hard rule, but a recommendation. Personally I stream at 3000 bitrate and 2000 buffer. The smaller the buffer the less variable the bitrate is, which makes Twitch and my connection happier.

I don't know what game you're playing and speedtest isn't a viable speed test for streaming. Use testmy.net instead. Tell us those things, but also make the changes above, do a stream for 5 minutes, then come back here and post the log file from that stream.

I usually stream CAll of Duty and the test with the testmy.net says that my upload connection is 8Mb/s.
I will come back at home on sunday, I'll post the log file on sunday :)

About the audio, I think I should set at 44.1, I don't know which is used by elgato, probably 44.1 :)
Thanks for your suggestion!

Just a slightly obvious note... run the testmy.net test on the connection you use for streaming.
Pointing this one out as we have had people run a speed test on their work connection, and not understand that the results they get there have no bearing on their home (streaming) connection.

I tested my home internet :)
