Setting up OBS
Recommended Settings - (Current as of v. 0.14.2)
The best settings for you will depend on a lot of different factors. Here are a few suggestions to get you started.
- Start with a mid-bitrate, around 2000 - 2500.
- Leave encoder at Software (x264)
- Leave audio bitrate at default setting.
- Choose a folder to store your streams locally. The default recording quality and recording format will work OK. (Your streams will be automatically recorded on our servers and can be downloaded from your StreamMe Video Manager, if you have archives enabled).
- Ensure your base resolution is set to your display's native resolution or the resolution you use in your game.
- Set your output resolution to the same value as your base resolution.
- Do not change downscale filter.
- Keep FPS at 30 to start and try to maintain this. Go down to 15 later, if you're experiencing issues or your network connection is poor.
Adjusting Settings / Troubleshooting
Once you've tried the recommended settings, you can adjust up or down depending on your network connection and the awesomeness of your computer. Below are a few more-detailed explainations of the basic settings.
The video bitrate should be based on your upload speed. You can google sites that will help you find out what your speed is. Your bitrate should be just below that. 3000-3500 is probably the max you'd want to raise your bitrate to.
If your computer can handle the CPU impact, you can leave this setting at Software (x264). Otherwise, if you have an nvidia card, you can try Hardware (NVENC) if CPU seems to be your issue. You can also try to lower CPU impact by clicking on Enable Advanced Encoder Settings and increasing the Encoder Preset.
Try the default setting to start and work your way up or down depending on your network connection.
If you have several devices to choose from, make sure the correct audio device is selected. Otherwise, leave as default.
Choose your native resolution. StreamMe also supports 4k resolution. Just be sure to use the following origin server when setting up your stream: rtmp://sea-origin.stream.me/origin
If you find that your stream quality is poor, try scaling down your output. Many streamers broadcast at 1280x720. This is the resolution that viewers will see your stream in. Lowering this can help with video quality but will decrease image size. We recommend the following upload speeds for each resolution.
- Upload Speed for 1080p (1920x1080): 3.5mbps-5mbps +
- Upload Speed for 720p (1280x720): 2mbps-3mbps
- Upload Speed for 480p (854x480): 1mbps-1.8mbps
- Upload Speed for 360p (640x360): 0.5mbps-0.8mbps
- Upload Speed for 240p (508x240): 0.50mbps
30 is the default setting and a good one to try to maintain. You can try lowering to 15, if your network connection is poor or increase to 60 if you're working with a better computer and network connection. 60 FPS would mostly only be good for gameplay with a lot of detail and/or fast-moving content.
5. Set up your stream
Open your StreamMe dashboard. Select the correct origin server closest to your location and notice your stream key (below Stream Title and Archive toggle):
In OBS, under File -> Settings, select Stream.
Select Custom Streaming Server as the Stream Type.
Copy the origin server into the URL field (you can use the copy button to the right of the origin server link and then ctrl +V into the OBS field).
Copy the Stream Key into the Stream key field. Keep this key secret! This is how you broadcast to your channel. If anyone ever gets a copy of your stream key, make sure to to use the reset stream key link on your StreamMe dashboard. Note: It is recommended you use the copy button to the left of your stream key to avoid copying extra spaces (which will make your key invalid).
Leave the Use authentication checkbox cleared.
Click OK to save your settings.
6. Start streaming!
Once your settings are good to go you can click on Start Streaming and watch yourself in action!
