OBS in one page: the name, the words and the settings that matter

Short on time? This is the compact version. Learn what the letters stand for, understand the handful of terms every OBS tutorial uses, and keep a cheat sheet of hotkeys and numbers within reach.

What does OBS stand for?

In streaming and screen recording, OBS means Open Broadcaster Software. “Open” points to the public source code, and “Broadcaster” to the original goal: sending live video to an audience.

The three letters are also used as an abbreviation in unrelated fields, so a general web search can mix topics. On this site, OBS always refers to the video capture and streaming program.

OBS versus OBS Studio

In everyday talk the two names are interchangeable. Strictly speaking, OBS Studio is the modern application that runs on Windows, macOS and Linux, while the older Windows-only generation is no longer what people install today.

The OBS glossary

Learn these ten words and most tutorials will make sense.

Scene
A saved layout of sources. Think of it as one “screen” of your show.
Source
A single ingredient inside a scene: a display, camera, image, text or audio input.
Canvas
The base resolution of your picture, for example 1920×1080.
Output
The resolution actually sent or recorded, which can be scaled down from the canvas.
Bitrate
How much data per second the video uses. Higher looks better but needs more upload speed.
Encoder
The part that compresses video. It can run on the processor or on dedicated graphics hardware.
Stream key
A private code that tells a platform which channel your video belongs to. Never share it.
Filter
An effect attached to a source, such as colour correction or noise suppression.
Transition
The animation used when switching scenes, like a fade or a stinger.
Dropped frames
Frames that never made it out, usually due to a weak connection or an overloaded computer.

Hotkeys worth setting up in OBS

OBS has no required default shortcuts, so assign your own in Settings, then press them even when another window has focus.

Start / stop recording

Try Ctrl + Shift + R so a stray key never ends a take.

Mute microphone

A push-to-mute key such as F8 saves you from sharing a cough with the audience.

Switch scene

Map your three main scenes to F1, F2 and F3 for instant cuts.

Save replay

Bind the replay buffer to a key you can reach in one move during action.

Start / stop stream

Give it an awkward combination so it is hard to press by accident.

Show / hide source

Toggle a camera or an overlay without opening the Sources list.

Common OBS mistakes beginners make

Black screen on capture. Try switching between display capture and game capture, or run OBS and the game with matching permissions.
Choppy video. Lower the output resolution or frame rate, or move to a hardware encoder.
Echo or doubled sound. You may be capturing the same audio twice, once from the desktop and once from the application.
Leaked stream key. If it ever appears on a stream or in a screenshot, reset it in your platform account.
