Best OBS settings for streaming
The right OBS settings depend on your upload, encoder, and platform. A walkthrough of resolution, bitrate, encoder choice, and the audio that matters.

The best OBS settings are the ones your computer and connection can sustain without dropped frames or audio glitches. There is no universal preset. The right answer is bounded by three things: your upload speed, your CPU or GPU encoder, and the platform you stream to.
Run the Auto-Configuration Wizard first
In OBS Studio, open Tools, then Auto-Configuration Wizard, and choose "Optimise for streaming". OBS will test your upload, measure your encoder performance, and pick a starting point. Treat its output as a starting point and check a real recording and stream for dropped frames, encoding overload and clear audio.
Use those numbers for your first stream. Adjust later only if you see real problems.
Resolution and frame rate
Output resolution and frame rate are set in Settings, then Video. Two values matter:
- Base (canvas) resolution: choose the layout and aspect ratio you intend to produce. It does not have to match an ultrawide or high-resolution monitor.
- Output (scaled) resolution: this is what is sent to the platform. 1920x1080 looks crisp but needs more bitrate. 1280x720 looks clean and is more forgiving on slower uploads and weaker encoders.
For frame rate, 30 fps is enough for chat-led streams and most slow-paced games. 60 fps is worth the cost for fast-paced action games and reaction-heavy content where motion clarity matters.
A clean 720p 60 fps stream looks better than a stuttering 1080p 60 fps stream every time. If in doubt, drop the resolution before you drop the frame rate.
Bitrate
In Settings, then Output, video bitrate is the single number that decides how much data per second your stream uses. Recommended starting points for Twitch:
- 720p 30 fps: 3000 to 4500 kbps
- 720p 60 fps: 4500 to 6000 kbps
- 1080p 30 fps: 4500 to 6000 kbps
- 1080p 60 fps: 6000 kbps under Twitch's standard published guidance
These are starting points, not a rule that non-Partners always have a separate hard cap. Use the current Twitch broadcasting guidelines (opens in a new tab) for your resolution and the options available to your account; enhanced broadcast modes can have different requirements.
As a cautious starting point, leave substantial upload headroom beyond your combined video and audio bitrate. A two-times margin is a planning suggestion, not a platform requirement. For example, an 8 Mbps video stream on a 10 Mbps upload leaves limited room for audio, overhead and other devices. Test it rather than assuming the remaining capacity guarantees success.
Encoder
In Output settings, the encoder choice depends on your hardware:
- NVIDIA NVENC: a hardware encoder available on supported GPUs. Check the options OBS actually offers for your device.
- AMD hardware encoding: available on compatible devices; quality and load depend on the hardware and settings.
- Intel Quick Sync (QSV): an option on supported Intel hardware; confirm compatibility and test the result.
- x264 (CPU): quality and load depend on its preset and your processor. Compare it with available hardware encoders using the same content; there is no universal quality winner at every setting.
For most modern PCs with a recent NVIDIA card, NVENC at the quality preset is the right answer. Check the recording for your own content before deciding whether another encoder is worth the extra load.
Audio
In Settings, then Audio, set the sample rate to 48 kHz. This is a practical production choice, not a claim that every platform requires that exact rate. Match your devices and OBS settings to avoid unnecessary conversion. Set the encoded output audio track bitrate in Output. This is not a separate bitrate control for each microphone or desktop source. Follow the destination's audio guidance.
The audio that actually matters is in your microphone source filters, not the global settings. Apply:
- Noise Suppression (NVIDIA Broadcast or RNNoise) to remove fan and keyboard noise
- Noise Gate to cut your microphone when you are not speaking
- Compressor to even out loud and soft moments
A microphone that sounds professional comes from filters and mic placement, not from buying a better microphone.
Common mistakes
A few settings choices that cause visible problems:
- Output resolution higher than base resolution. OBS scales up. The stream will look soft.
- A bitrate higher than your upload can sustain. Drops frames during peak network activity.
- Storage that cannot sustain your recording data rate. Check recording settings and disk performance if the file stutters while the live output is healthy.
- Game capture set to "Capture specific window" when the game uses multiple processes. Try "Capture any fullscreen application" instead.
When to revisit your settings
Re-run the Auto-Configuration Wizard if you upgrade your GPU, your CPU, your internet, or your monitor. Recheck if your content or stream destination changes, or the output develops a problem. Most quality problems are scene composition, lighting, and microphone, not bitrate.
