    How do I use OBS Studio to stream or record?Save

    Quick Answer

    Download OBS Studio from obsproject.com (it is free), open Settings, set Video to 1920 by 1080 base and output with 60 FPS, and set Output Mode to Advanced. Pick NVENC if you have an Nvidia GPU, AMD VCN if you have an AMD GPU, otherwise x264. For 1080p60 streams use 6000 Kbps bitrate, for 1080p30 use 4500 Kbps.

    Build at least one Scene, add your Display Capture or Game Capture as a Source, add your microphone as an Audio Input Capture, and put your webcam on top with Video Capture Device. Press Start Recording or Start Streaming when ready.

    What OBS Studio is good for

    OBS (Open Broadcaster Software) is free, open source, and runs on Windows, macOS, and Linux. It powers most live streams on Twitch, Kick, and YouTube Live, plus a huge chunk of recorded YouTube content. The reason it dominates is the combination of zero cost, hardware encoder support, and the ability to mix multiple sources into one clean output. The price is a learning curve, because the default settings are conservative and the UI hides power features behind menus.

    First boot: the auto configuration wizard

    The first time you launch OBS Studio, it offers an auto configuration wizard. Take it. Tell it whether you plan to stream or record, what platform, and it will guess sensible settings based on a benchmark of your hardware and connection. Treat the result as a starting point, not the final answer, but it saves you ten clicks.

    Video settings that matter

    Open Settings then Video. Three fields decide most of the quality.

    • Base (Canvas) Resolution: usually 1920 by 1080, the resolution of your main monitor.
    • Output (Scaled) Resolution: what gets sent out. 1920 by 1080 for high upload bandwidth, 1280 by 720 if you upload under 6 Mbps.
    • Common FPS Values: 60 for gameplay, 30 for talking head or screen recordings.

    Then go to the Output tab and switch Output Mode to Advanced. Under the Streaming tab, change Encoder. The order of preference is: NVENC H.264 (Nvidia RTX), AMD HW H.264 AV1 or HEVC (modern AMD), then x264 (CPU based, slower and heavier). Hardware encoders offload the work to the GPU so your CPU stays free for the game or the app you are recording.

    Bitrate, the setting nobody understands

    Bitrate decides image quality and how much your upload pipe is consumed. Pick from this table:

    • 1080p60 stream: 6000 to 8000 Kbps
    • 1080p30 stream: 4500 to 6000 Kbps
    • 720p60 stream: 3500 to 4500 Kbps
    • Local 1080p60 recording: 25000 Kbps or higher (you have no bandwidth ceiling on disk)

    Run a real upload speed test before you stream. You want your bitrate to be no more than 75 percent of your upload speed, so a 10 Mbps upload caps out at around 7500 Kbps stream bitrate. Anything higher and frames will drop.

    Scenes and sources, the mental model

    OBS layers sources within scenes; build one scene per situation you will switch to.

    A Scene is a saved layout. A Source is one thing inside a Scene (a game, a camera, an image). Most streamers build at least four scenes:

    1. Starting Soon: a static image with countdown, music, and chat overlay.
    2. Main: Game Capture or Display Capture, webcam in a corner, microphone audio.
    3. Just Chatting: webcam fullscreen, microphone, chat overlay.
    4. Be Right Back: static image and music.

    Build the scenes once and switch between them with the click of a button (or a Stream Deck if you have one). Source order matters: items at the top of the Sources panel sit on top of items below. Drag your webcam to the top so it floats above the gameplay.

    Audio: the mixer and how to avoid clipping

    The audio mixer sits at the bottom of OBS. Each source has its own level meter and volume slider. The colour zones tell you what to aim for: green is safe, yellow means loud, red means clipping (distortion).

    Speak at the volume you actually use during a stream and adjust the microphone slider so peaks sit between 20 and 10 dB below the top of the meter (the yellow zone). Anything that touches red will sound crunchy on the recording.

    Add filters by clicking the gear next to a source, then Filters. A Noise Suppression filter (try the RNNoise option) cuts background hum. A Compressor filter levels out volume swings so quiet speech and loud laughs both come through clean.

    Recording vs streaming

    Recording is set under Output, Recording tab. Use MKV as the file format. It survives crashes. You can remux to MP4 from inside OBS afterwards (File menu, Remux Recordings). For streaming, plug in the Stream Key from Twitch, YouTube, or Kick under Settings, Stream.

    Common first time mistakes

    Black screen on Game Capture usually means you forgot to run OBS as the same user level as the game. Right click the OBS shortcut, Run as Administrator. Mic not picking up means you selected the wrong device in Audio Settings, switch to Default and then back. CPU at 100 percent means you are using x264 with too high a bitrate, switch to your hardware encoder.

    The takeaway

    OBS Studio is powerful because every setting is exposed, which is also why it is intimidating. Get the video resolution, encoder, and bitrate right; build a couple of scenes; and tune the mic so it never touches red. Once those four things are dialled in, the rest is fine tuning and overlays.
