Under Settings > Video, set your desired Base (Canvas) Resolution and Output (Scaled) Resolution, typically 1920x1080 for high-definition streams.

2. Adding Zoom as a Source in OBS

Capture the Zoom meeting window or your screen to include it in your OBS scene.

Follow the installation instructions specific to your operating system to set up the virtual audio device.

b. Routing Zoom Audio through Virtual Audio Cable

Open Zoom and navigate to Settings > Audio.
Under the Speaker section, select the virtual audio cable (e.g., "Cable Input (VB-Audio Virtual Cable)") as the speaker output device.

c. Adding Audio Sources in OBS

In OBS, click the "+" icon in the Sources panel and select Audio Input Capture to add your microphone:

Name the source (e.g., "Microphone").
Select your physical microphone device from the dropdown menu.

Again, click the "+" icon in the Sources panel and select Audio Output Capture to add Zoom's audio:

Name the source (e.g., "Zoom Audio").
Select the virtual audio cable as the device.

4. Configuring YouTube Live Settings

Set up your YouTube account to receive the live stream from OBS.

a. Obtaining the YouTube Stream Key

Once satisfied, click Go Live to broadcast your Zoom meeting to YouTube.

Additional Tips and Best Practices

Optimizing Stream Quality

Resolution and Bitrate: Ensure that your OBS settings match YouTube's recommended streaming parameters for optimal quality.
Monitor CPU Usage: Streaming can be resource-intensive. Close unnecessary applications to free up system resources.

Enhancing Audio Management

Avoiding Feedback Loops: Use headphones during the Zoom meeting to prevent audio from your speakers re-entering your microphone.
Audio Level Balancing: Adjust audio levels in OBS to ensure clear and balanced sound between your microphone and Zoom audio.

Using Overlays and Graphics

Visual Enhancements: Add overlays, such as lower thirds or branding elements, to make your stream more professional.
Scene Transitions: Utilize OBS's scene transition features to switch between different layouts seamlessly.

Testing and Troubleshooting

Pre-Stream Testing: Conduct a test stream to ensure all configurations work correctly before going live to your audience.
Monitoring Stream Health: Keep an eye on YouTube's Live Control Room metrics to identify and address any streaming issues promptly.

Troubleshooting Common Issues

Encountering problems during the streaming setup is common. Here are solutions to frequent challenges:

1. No Audio in Stream

Verify that the virtual audio cable is correctly selected in both Zoom and OBS.
Ensure that OBS has the correct audio input and output capture sources configured.
Check system sound settings to confirm that audio is being routed through the virtual cable.

2. Lag or Delay in Video Feed

Lower the video bitrate in OBS settings to reduce the load on your internet connection.
Ensure that no other bandwidth-heavy applications are running during the stream.
Use a wired internet connection instead of Wi-Fi to minimize latency.

3. OBS Not Capturing Zoom Window

Ensure that Zoom is running and the meeting window is active.
Run OBS as an administrator to grant necessary permissions for window capture.
Try using Display Capture instead of Window Capture if issues persist.

Conclusion

Streaming a Zoom video call to YouTube using OBS allows you to reach a broader audience while maintaining interactive capabilities. By meticulously setting up OBS, managing audio through virtual cables, and configuring YouTube's live streaming settings, you can deliver high-quality, professional live streams. Remember to optimize your settings, enhance your stream with overlays, and conduct thorough tests to ensure a seamless broadcasting experience.
