1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsFor a reliable standard-dynamic-range YouTube stream, start with H.264, CBR, a 2-second keyframe interval, Rec. 709 color and a bitrate matched to your resolution and frame rate. YouTube recommends 17 Mbps for 1080p60, 14 Mbps for 1080p30, and 8 Mbps for 720p at either 30 or 60 fps. Those are video bitrates, not total upload speeds; leave about 20% upload-bandwidth headroom and choose a setting your computer and connection can sustain.
Recommended OBS settings at a glance
These are a practical starting point for an ordinary SDR stream. YouTube’s encoder recommendations are platform guidance, not a guarantee of visual quality or a universal OBS preset. OBS control names and available encoders vary by operating system, GPU, drivers and OBS version.
| OBS setting | Starting point |
|---|---|
| Video encoder | H.264, using a hardware or software encoder supported by your system |
| Rate control | CBR |
| Keyframe interval | 2 seconds |
| Video bitrate | Use YouTube’s recommended H.264 bitrate for the selected resolution and frame rate |
| Audio | AAC stereo, 44.1 kHz, 128 kbps |
| Protocol | RTMPS when available |
| SDR color | Rec. 709, 8-bit |
In OBS, these options are generally under Settings > Output for encoder, rate control, bitrate and keyframe interval, and Settings > Video for canvas/output resolution and frame rate. The exact labels and controls depend on the selected encoder.
Choose the right bitrate for your resolution
The figures below are YouTube’s recommended H.264 ingest video bitrates, rather than total upload rates. YouTube’s encoder-settings page, accessed October 3, 2026, lists these values without displaying a publication year. Use the row that matches the resolution and frame rate sent by OBS.

| Ingest resolution and frame rate | H.264 minimum | H.264 recommended |
|---|---|---|
| 2160p (4K) at 60 fps | 14 Mbps | 50 Mbps |
| 2160p (4K) at 30 fps | 11 Mbps | 42 Mbps |
| 1440p at 60 fps | 8 Mbps | 34 Mbps |
| 1440p at 30 fps | 7 Mbps | 21 Mbps |
| 1080p at 60 fps | 6 Mbps | 17 Mbps |

| 720p at 30 fps | 3 Mbps | 8 Mbps |
| 480p at 30 fps | 0.4 Mbps | 4 Mbps |
| 360p at 30 fps | 0.4 Mbps | 4 Mbps |
For many streams, 1080p30 at 14 Mbps is a sensible starting choice; use 1080p60 at 17 Mbps when the content benefits from smoother motion and the system and connection can sustain it. For a constrained connection or machine, 720p at 8 Mbps may be more dependable than an unstable 1080p stream. These are starting decisions, not claims that one format always looks best.
YouTube also publishes different bitrate recommendations for AV1 and H.265/HEVC. For example, its recommended values are 12 Mbps for 1080p60, 10 Mbps for 1080p30, and 6 Mbps for 720p at 30 or 60 fps; corresponding minimums are 4 Mbps, 4 Mbps, 2 Mbps and 2 Mbps. Do not apply those figures to an H.264 stream: select the row for the codec actually being sent.

How to choose resolution, frame rate and encoder
Match the stream to the content
Higher resolution carries more picture detail; higher frame rate can make motion look smoother. Both require more bitrate and encoding capacity. Choose the highest combination your upload connection and computer can maintain reliably, rather than treating 1080p60 or 4K as the default.

Use an encoder your system can sustain
YouTube accepts H.264, H.265/HEVC and AV1 video, up to 60 fps. H.264 is a straightforward baseline for a typical SDR setup. Choose another codec only if OBS, your hardware encoder and your intended workflow support it, and use that codec’s own bitrate recommendations. The available OBS encoder names depend on your system.
Account for latency
YouTube says 4K/2160 streams cannot use its low-latency optimization and are set to normal latency. If low latency matters, do not assume a 4K stream can use that option.

Set the encoder details that affect delivery
CBR and keyframes
Use CBR and set the keyframe interval to 2 seconds. YouTube recommends a 2-second frequency and says not to exceed 4 seconds. These settings are key starting points for the encoder configuration.

Advanced H.264 options
For advanced encoder details, YouTube recommends square pixels, progressive scan, two B-frames, one reference frame and CABAC entropy coding. Some encoders expose these controls and others do not; use the options available for your selected encoder rather than assuming every OBS setup presents the same fields.
Audio
For ordinary stereo audio, use AAC, 44.1 kHz and 128 kbps. YouTube lists AAC or MP3 for stereo. For 5.1 surround over RTMP/RTMPS, AAC is required; YouTube recommends 48 kHz and 384 kbps.
Color and HDR
For SDR, use Rec. 709 and 8-bit depth. For HDR, YouTube recommends HEVC and 10-bit depth and says AV1 is not supported for HDR. HDR needs a compatible end-to-end workflow and hardware; selecting a color option alone does not make an SDR source HDR.

Configure OBS and connect it to YouTube
- Set the video format. In OBS, open Settings > Video. Choose a base and output resolution appropriate for the content and connection, then set the frame rate. Use the matching resolution/frame-rate row from the bitrate table.
- Set output encoding. Open Settings > Output and select the streaming output controls if OBS offers an output-mode choice. Choose a supported H.264 encoder, CBR, the matching YouTube recommended video bitrate and a 2-second keyframe interval. Encoder-specific options vary.
- Set audio. In OBS audio settings and the encoder’s audio controls, choose AAC stereo at 44.1 kHz and 128 kbps for an ordinary stream, where those controls are available.
- Choose the YouTube ingest connection. In YouTube’s live setup, use the stream key and server details shown for the stream. In OBS, open Settings > Stream, select YouTube or configure the server and key as required by the chosen connection method. Keep the stream key private; anyone with access to it may be able to broadcast to your channel.
- Prefer secure transport. Use RTMPS if the available YouTube/OBS connection setup offers it. YouTube describes RTMPS as a secure extension of RTMP.
- Test before the event. Start OBS with representative movement and audio, check the Live Control Room preview, and inspect stream health and messages. YouTube says, “Make sure to test before you start your live stream.”
Menu names can change between OBS versions and platforms. For encoder-specific requirements, consult YouTube’s encoder settings and the setup instructions in Create a YouTube live stream with an encoder.
Make sure your upload connection has headroom
The recommended video bitrate is only useful if the connection can sustain it. YouTube advises that total stream bitrate must not exceed available upload bandwidth and recommends leaving 20% headroom. Other people and devices sharing the connection can reduce the bandwidth available to OBS.
- Run an upload speed test close to the time and place you plan to stream.
- Include audio and any additional stream traffic when considering total bitrate; the video bitrate table is not a total-network-usage figure.
- Account for other people using the same connection, especially during the live event.
- Use a reliable network and test under conditions similar to the event.
- If the connection cannot reliably support the selected bitrate with headroom, lower the bitrate and, if needed, reduce resolution or frame rate.

Preflight checklist for a scheduled stream
- Arrange the stream in YouTube ahead of time and confirm the correct stream key is configured in OBS.
- Start the encoder at least 15 minutes before the scheduled event, as YouTube’s preparation checklist advises.
- Test with audio and movement similar to what viewers will see, then check the Live Control Room preview.
- During the event, keep checking stream health and messages as well as the actual audio and video quality.
- Verify that any local archive files and the YouTube watch page are available as expected.

Troubleshoot dropped frames, disconnects and overload
| Symptom | What to check and try |
|---|---|
| Network or connection warnings | Check available upload bandwidth and other users’ activity. Ensure total bitrate fits the connection with YouTube’s recommended 20% headroom; lower bitrate and, if needed, resolution or frame rate. |
| Encoder overload or unstable rendering | Check whether the computer and selected encoder can sustain the resolution and frame rate. Reduce resolution or frame rate if the system cannot keep up; choose a supported encoder. |
| Bitrate is set but delivery remains unstable | Confirm the selected bitrate row matches the actual codec, resolution and frame rate. Test again under conditions similar to the event and inspect stream health in YouTube’s Live Control Room. |
| Preview or stream does not appear as expected | Confirm OBS is connected to the intended YouTube stream with the correct stream key and server details, then check YouTube’s preview and encoder status before going live. |
| Audio is missing or poor | Check the OBS audio source and meter, then verify the selected audio codec, channel layout, sample rate and bitrate against the stream configuration. |
Network and encoder problems have different causes: lowering video bitrate may help a bandwidth constraint, while lowering resolution or frame rate can also reduce encoding demands. YouTube recommends testing and monitoring, but no single OBS setting can diagnose every computer or network.
Copyright and YouTube live-stream rules
Encoding settings do not grant permission to stream the material in your broadcast. Use video, music and other material you have rights to use, and review YouTube’s current live-stream requirements before broadcasting. A technically healthy stream may still face a copyright claim or enforcement action if its content is not authorized. Likewise, changing resolution, codec or bitrate does not determine whether content complies with YouTube’s rules.
Or let it run in the cloud
If your goal is keeping a pre-recorded YouTube stream running rather than encoding a camera or desktop live in OBS, StreamNeo is a cloud alternative: upload a recording or build a playlist, add your YouTube stream key once, and go live. It loops uploaded videos; it does not broadcast from a camera.
Quick Recap
- Nothing has to stay on at home: the stream runs from the cloud, so your computer can be off.
- Every slot streams the video as uploaded, at any quality up to 4K 60fps, for one flat price per slot.
- It automatically recovers if YouTube drops the stream.
- The first day is free with no card, one free day per account.
- Monthly: $9.99 per month.
