SSBM Streaming Guide – Part 5: Configuring OBS

Now that you have all your hardware, you need software that will record and stream your content.

The most popular free software for this is a program called Open Broadcaster Software.

The software has two versions: OBS Classic, which is the original brew, and OBS Studio (previously called OBS Multiplatform) that runs on Windows, Mac, and Linux.

The difference? Well, if you have a Mac or Linux PC then you’ll obviously only be able to use OBS Studio. If you have a Windows machine, then you have a choice.

OBS Studio is new compared to Classic. Studio aims to have all the features of Classic and add more. Currently, I think nearly all of the features in Classic are in Studio.

However, I’ve been using Classic since it was even in beta. If I were you, though, I’d try both and see which one you like better.

This guide will be focusing on OBS Classic, although most of the settings are similar so you could also apply them to OBS Studio.

Here is the download link.

Once you have installed it, open up OBS.

At the top, click on Settings -> Settings.

Section by section, I’ll tell you the proper settings.

1. General

Language: English (or your preference)

Setting Profile: Give your profile a name (Smash Stream would be good)

The check boxes below should all be unchecked unless you want them to be checked.

2. Encoding

Encoder: x264 is great, if you know what the other options do then choose your favorite.

Use CBR: Checked

Max Bitrate (kb/s): The maximum amount here is 3500. If you can this site to test your speed. Multiply your upload Mbps by 1000 to get your kb/s. If your maximum upload speed is below, say, 3700, then set your max bitrate to your upload speed minus 200.

If you are recording, then you can set this as high as you want (5000-10000 are good) but make sure your computer can handle it.

Enable CBR padding: checked.

Use Custom Buffer Size: Unchecked.

Audio Encoding: Leave this alone unless you know audio.

3. Broadcasting Settings

Mode: Your desired mode.

Streaming Service: Twitch (or hitbox for Project M) (or your favorite streaming service!)

FMS URL: Choose your nearest city.

Stream Key: Go to your dashboard on Twitch, click on Stream Key, and copy and paste this value into this setting.

Auto-Reconnect: I like this checked so that the stream gets back online ASAP.

Minimize network impact: Leave this unckecked unless you’re streaming Netplay or you’re hosting a League of Legends tournament at the same time.

Automatically save stream to file: this lets you record and stream at the same time.

File Path: Where you want to save your recording if recording. .mp4 is the recommended file type.

Replay buffer: Not going to cover this feature. Google it if you’d like.

4. Video

Video Adapter: Should be one option. If there are two, make it your graphics card.

Base Resolution: Always use custom. Here are some combinations I recommend.

1280×720 – Good for anything except 1080p Smash 4. Could be 30 fps or 60 fps

1920×1080 – Smash 4 1080p at 30 fps.

If your internet sucks, go for a Resolution Downscale. Otherwise, keep it at None.

Disable Aero: If this option is available, check it.

5. Audio

Desktop Audio Device: Default

Microphone/Aux Audio Device: Select your microphone if you have one. Otherwise, disable.

Leave the other settings the same.

6. Hotkeys

If you want to set some hotkeys up, here is the place!

7. Advanced

Keep all of these settings the same other than the following:

Video -> CPU Preset: veryfast

Video -> Encoding Profile: main

Video -> Keyframe Interval : 2


That’s it for settings. In the next split, I’ll be talking about building your stream or recording scene in OBS. Now is a good time to try plugging all your devices in and just fiddling with the software.
