You can run two simultaneous 4K 60fps YouTube Live loops from one PC, but the right setup depends on whether both broadcasts show the same video or different videos. For the same loop, one encoded feed can be bound to multiple broadcasts through YouTube’s Live Streaming API. For different loops, use a separate stream and output for each broadcast, then verify that your PC’s encoders and internet upload can sustain both.
First decide whether the loops are identical
“Two loops” can mean two YouTube broadcasts carrying the same video, or two broadcasts carrying different videos. That distinction determines whether you need one outgoing encode or two.
| What each broadcast shows | Stream design | Main constraint |
|---|---|---|
| The exact same loop | One incoming stream can be bound to multiple broadcasts using YouTube’s Live Streaming API. | One PC encode and one outgoing feed; both broadcasts receive the same incoming content. |
| Different loops | Create a distinct stream resource for each broadcast and send each its intended video. | Two live outputs, their combined upload bitrate, and enough encoder capacity for the workload. |
YouTube documents both the shared-stream arrangement and the separate-stream approach in its Live Streaming API guide. The shared arrangement is documented at the API level; a particular YouTube Studio account or interface may not expose the same workflow as a simple button, so do not assume a specific Studio path.
Set up one feed for two broadcasts
Use this approach only when both broadcasts should carry the same live video and audio. Binding the same incoming stream to two broadcasts does not create a second, independently edited loop.

- Bind both broadcasts to that same incoming stream through the Live Streaming API.
- Start the single encoder output and verify that both broadcast feeds receive the same content and show healthy ingest.
The API guide describes this pattern with a 24/7 feed and another broadcast that shows a subset of the feed. It does not establish a universal Studio UI path or account-specific availability; consult the API workflow if you need this exact binding arrangement.
Set up two different loops
When the videos differ, one shared feed cannot carry both. Configure a separate incoming YouTube stream for each broadcast and send the intended loop to each one.

- Run both together in a test broadcast and check encoder performance, outgoing bitrate, dropped frames, audio, and YouTube stream health before relying on them.
Two outputs have to be played, encoded as configured, and sent concurrently. Their actual resource demand depends on your PC, codec, encoder implementation, source content, and other workloads; no single CPU, GPU, or RAM minimum can be specified for every setup.
Use YouTube’s 4K60 encoder settings
YouTube Help’s current live-encoder guidance, checked in 2026, lists these 2160p60 settings. The bitrate figures are per stream. Minimums are not recommended quality targets: aim for the recommended bitrate if your sustained upload can support it.

| Setting | YouTube guidance for 4K / 2160p at 60 fps |
|---|---|
| AV1 or H.265 / HEVC bitrate | 35 Mbps recommended; 10 Mbps minimum per stream |
| H.264 bitrate | 50 Mbps recommended; 14 Mbps minimum per stream |
| Rate control | CBR |
| Keyframe frequency | 2 seconds recommended; do not exceed 4 seconds |
| Ingestion protocol | RTMP or RTMPS; YouTube recommends RTMPS |
| Audio | AAC or MP3; 128 Kbps stereo recommended |
For two independent streams at YouTube’s recommended video bitrates, plan for about 70 Mbps combined with AV1 or HEVC, or 100 Mbps combined with H.264, before allowing network headroom. These totals are arithmetic from YouTube’s per-stream recommendations, not separate YouTube recommendations. Test sustained upload performance; a momentary speed-test result does not guarantee that the connection will hold two high-bitrate streams. If it cannot sustain the selected total with headroom, lower the targets or use another connection or streaming design.
YouTube says it automatically detects encoder settings and transcodes incoming live video into formats for viewers. You still need a stable ingest at your chosen source resolution and frame rate. At 4K/2160p, YouTube’s guidance says low-latency optimization is unavailable; the stream uses normal latency. See YouTube’s live encoder settings for the current recommendations.

Check that the PC can encode both outputs
With one shared feed, the PC sends one encoded output. With two distinct loops, it must sustain both outputs under the actual workload. Hardware encoding can be a practical starting point if your GPU provides it, but the specific model, codec support, number of concurrent sessions, and scene complexity matter. Test your exact settings rather than relying on a general hardware minimum.
- In OBS, use its Auto-Configuration Wizard as a starting point, then confirm the output settings match YouTube’s 4K60 guidance.
- For distinct feeds, watch encoder overload, skipped or lagged frames, and rendering performance while both streams are active.
- Check your GPU’s model-specific encoder capabilities. NVIDIA’s January 30, 2025 guide notes that some then-current GPUs include dual or triple encoders, but this is not true of every GPU and does not establish a universal requirement for two separate encoder blocks.
- OBS’s connection goes directly from your computer to the streaming service. If frames drop, investigate the local upload path and connection to YouTube rather than assuming OBS relays the stream through its own servers.
OBS documentation and its streaming connection troubleshooting guide can help distinguish connection issues from encoder or rendering problems. NVIDIA’s broadcasting guide is specific to supported NVIDIA hardware; its recommendations should not be treated as universal advice for every PC.
Test both loops before scheduling them
- Run a private or unlisted test broadcast, or another test workflow appropriate for your channel.
- Use representative motion and audio. Static footage alone may not reveal the load of a more complex loop.
- For two distinct feeds, run both at once for long enough to observe sustained encoding and network behavior.
- Check outgoing bitrate, frame rate, audio, dropped frames, encoder warnings, and YouTube’s stream-health indicators.
- Only schedule the intended broadcasts after both feeds remain stable at the settings you plan to use.
YouTube specifically advises testing before a live stream and monitoring stream health. Its health documentation includes issues such as low bitrate, frame-rate mismatch, missing audio, and video-ingestion starvation. See YouTube’s encoder settings guidance and the Live Streaming API stream resource documentation.
Troubleshoot common two-stream problems
| Symptom | Likely cause | What to check or change |
|---|---|---|
| YouTube reports low bitrate or unstable ingest | The connection cannot sustain the combined outgoing rate, or upload is fluctuating. | Check measured sustained upload while both streams run; reduce the bitrate targets or reconsider sending both feeds over that connection. |
| Encoder overload, lagged frames, or skipped frames | The PC cannot sustain the selected resolution, codec, and number of outputs under current load. | Inspect OBS performance and encoder statistics; test a hardware encoder if supported, or reduce workload/settings and retest both outputs together. |
| One broadcast shows the wrong video | The output or stream credentials may be associated with the wrong broadcast, or the setup shares one feed when distinct content is required. | Confirm each output is mapped to its intended stream resource and video. Use separate streams for different loops. |
| Frame-rate mismatch warning | The configured or delivered frame rate differs from the intended 60 fps setting. | Check source and encoder frame rate, then verify YouTube’s ingest health during a fresh test. |
| No audio on one broadcast | That output may have no audio source or may be using the wrong audio track or format. | Check each output’s audio routing and confirm audible test content reaches the matching broadcast. |
| Video ingestion starvation | The encoder or local connection is not delivering frames consistently. | Check PC load and encoder performance alongside upload stability; test again with both outputs active. |
