How to set up OBS for streaming, and the five settings that matter
By Elan Harpaz · Published 2026-08-20
Install to live takes ten minutes. The settings the auto-configuration wizard gets wrong take five, and they are the ones that decide whether you drop frames.
Your encoder tops out at 1080p60. A higher-end encoder would go further.

Getting into OBS is genuinely easy: install it, add your camera and microphone as sources in a scene, paste a stream key from your platform, press Start Streaming. That part takes ten minutes and does not need a guide. What needs a guide is the settings page, because OBS ships with defaults chosen to work everywhere rather than to work well here.
| Setting | Set it to | Why |
|---|---|---|
| Encoder | Hardware (NVENC, AMF, or QuickSync) | It runs on the graphics card, so encoding stops competing with your game for CPU |
| Rate control | CBR | Live platforms ingest a constant rate; a variable one is what produces the spikes the headroom exists to absorb |
| Bitrate | 70 percent of sustained upload, capped at the platform’s number | The 70% Headroom Rule, and on Twitch standard the cap is 6,000 kbps |
| Keyframe interval | 2 seconds | Twitch and YouTube both specify it in their published encoder guidance |
| Output resolution | 1920x1080 or lower | The Twitch 6000 Ceiling: standard ingest cannot carry 1440p, so sending it wastes bitrate on pixels the platform will not serve |
Do not let the wizard set your bitrate
OBS opens with an auto-configuration wizard, and it is a good way to get sources on screen and a sane encoder selected. It is a bad way to set your bitrate, because it runs a bandwidth test at that moment and reports what your connection managed once. That is a peak. A stream has to survive the floor: the minute your household starts a backup, or a mobile line hands you to a busier cell. The 70% Headroom Rule exists precisely to correct for the number the wizard is looking at. Run the wizard, then go into Settings and set the bitrate by hand against the upload you can hold all evening rather than the one you hit for eight seconds.
Two things worth adding once it works
- A noise gate and a compressor on the microphone, both built into OBS under Filters. The gate closes when you are not talking, which is what stops your keyboard and your fans being part of the stream; the compressor evens out the difference between your normal voice and your excited one.
- A separate Starting Soon and BRB scene. Not decoration: it is what you cut to when something breaks, and building it before you need it is the difference between a pause and a dead stream.
Free, open source, and the lightest option on CPU, which is the whole reason it is still the default in 2026.
The same core video engine wrapped in alerts and themes. Pick it if a guided setup gets you live this week, and know it costs measurably more CPU and RAM for the same scenes.
Frequently asked
What bitrate should I set in OBS?
About 70 percent of your real sustained upload speed, capped at what your platform accepts. On Twitch standard that cap is 6,000 kbps, so a 1080p60 stream wants roughly 8.6 Mbps of upload underneath it. Set it by hand rather than taking whatever the auto-configuration wizard measured once.
Should I use NVENC or x264 in OBS?
NVENC, or your GPU’s equivalent, if you have one. Hardware encoding runs on a dedicated block of the graphics card and leaves the CPU to the game. x264 on the CPU can look slightly better at the same bitrate and it competes directly with whatever you are playing, which is why it belongs on a second PC or on a machine that is not gaming.
What keyframe interval should OBS use?
Two seconds. Twitch and YouTube both ask for it in their published encoder guidance, because that interval is what their servers cut the stream into segments on. Leaving it on automatic is the most common cause of a stream a platform accepts and then transcodes badly.
