For example, YouTube recommends 8 Mbps for H.264 at 720p30 and 14 Mbps at 1080p30. Treat those as ingest recommendations—not a guarantee your internet connection can sustain them—and test the actual demo scene before relying on it for a continuous stream.
Recommended OBS settings for YouTube Live
These are a practical starting point for an ordinary SDR product demonstration using RTMPS. Match the settings to the stream key and encoder options available in your setup; HDR is a separate workflow.

| Setting | Starting point | Why it matters |
|---|---|---|
| Protocol | RTMPS | YouTube recommends RTMPS, the secure extension to RTMP. |
| Video encoder | H.264 | A straightforward baseline for standard SDR streaming. |
| Rate control | CBR | Provides a constant target bitrate for the live feed. |
| Keyframe interval | 2 seconds | YouTube recommends two seconds and says not to exceed four seconds. |
| Color | Rec. 709, 8-bit | Recommended SDR color configuration. |
| Audio codec | AAC | YouTube lists AAC or MP3 for RTMP/RTMPS; AAC is a suitable starting choice. |
| Stereo audio | 128 Kbps, 44.1 kHz | YouTube’s listed stereo audio recommendation. |
| Latency | Normal | Prefer normal latency if the demo does not depend on real-time audience interaction. |
YouTube also supports H.265 and AV1 ingest, with their own recommendations. Use another codec only after confirming that your OBS encoder and YouTube stream-key configuration support it. YouTube’s HDR instructions require supported hardware and HEVC, with specific color and protocol configuration; do not apply HDR settings to a standard SDR demo by default.
Choose resolution, frame rate, and bitrate together
Pick an output that makes labels, controls, and other product details readable, then select the matching row in YouTube’s current encoder recommendations. These H.264 examples are YouTube recommendations, not measured connection guarantees:

For the full set of resolutions, frame rates, and codecs, check YouTube’s live encoder settings rather than assuming the examples cover every combination. YouTube transcodes live streams into multiple viewer formats, but that does not remove the need to deliver a stable ingest signal.
Match motion to the frame rate
A static product display may not benefit from 60 fps. Closeups, hand movement, or fast camera motion can make a higher frame rate useful, but it also changes the bitrate requirement. Test the product and movements viewers will actually see, and check that small on-screen details remain legible.
Check upload capacity before committing to a continuous run
Measure outbound upload speed; download speed alone does not show whether OBS can sustain the stream. YouTube recommends keeping 20% upload-bandwidth headroom. Leave capacity for other network traffic and any backup stream, and remember that OBS may receive less than the connection’s advertised speed when the network is shared.

- Run an upload-speed test on the network and at the location where the stream will operate.
- Choose a resolution and frame rate that make the demo clear, then use YouTube’s matching bitrate recommendation as the target.
- Test with the intended camera movement, lighting, overlays, and sound. Watch YouTube’s preview and stream-health messages.
- If frames drop or stream health deteriorates, lower the target bitrate or address the network bottleneck before trying to increase quality.
OBS documents dynamic bitrate as a beta measure that can lower bitrate during congestion. OBS cautions that it does not fix the underlying connection problem, and a lower bitrate reduces image quality. Treat it as a possible mitigation, not a substitute for adequate, stable upload capacity.
Choose an encoder your workstation can sustain
OBS says hardware encoding generally shifts work from the CPU to a specialized GPU component. Modern hardware encoders can offer good quality with minimal performance impact, while earlier generations may produce lower image quality at the same bitrate. Select an encoder actually available on your system and evaluate it under the full OBS scene load; the evidence does not support recommending a particular GPU model.
Preflight the demo before leaving it live
Use YouTube’s streaming tips and check the live preview and health indicators before the continuous run. YouTube’s guidance says: “Make sure that you test before you start your live stream. Tests should include audio and movement in the video similar to what you’ll be doing in the stream.”

- Confirm that the product is framed clearly and labels or interface text can be read at the selected output resolution.
- Listen for clear speech and make sure product handling noise does not overwhelm the voice.
- Review the preview, stream-health messages, and viewer-facing stream before treating the setup as ready.
- If using a backup encoder, test failover rather than assuming it will work when needed.
A successful preflight reduces avoidable setup risk; it does not guarantee an uninterrupted 24/7 stream. OBS settings alone cannot provide an unattended recovery plan for application or operating-system failure, power loss, ISP outages, or YouTube ingest interruptions. If continuity is critical, plan monitoring, recovery procedures, and power and network resilience, then test them.
Follow YouTube’s content rules for a product demo
Before leaving the channel live, make sure the stream’s audio and visuals are yours to use or properly licensed. Product demos can include music, screens, or third-party material that raises copyright questions even when the product itself is the focus. Review YouTube’s current live-streaming requirements and applicable copyright rules before broadcasting; encoder settings cannot resolve a rights issue.
