In the world of live streaming, audio and video sync is paramount. A few milliseconds of misalignment can make your stream look unprofessional and unprofessional. In this video, we'll show you how to use OBS and NDI to get your audio and video ideally in sync, ensuring a flawless live presentation.

Problem:
Audio and video sync issues can arise from a variety of factors, including:

Latency:
The time it takes for audio and video signals to travel between devices and processing systems.
Frame rates: Different devices and codecs may have different frame rates, which can cause jitter and sync problems.

Codec compression:
Codec compression can impact audio and video quality, potentially introducing delays or artifacts.

Solution:
Combining OBS and NDI provides a powerful solution for ensuring audio and video synchronization in live productions.

Here's how it works:
Use NDI Sources: OBS can receive audio and video signals from NDI-enabled sources, such as cameras, microphones, and switchers. This allows you to seamlessly incorporate multiple sources into your live stream without worrying about sync issues.

Adjust Delay Compensation:
OBS offers advanced audio delay compensation features. This allows you to fine-tune the audio delay based on your specific sources and equipment.

Optimize Encoding Settings:
Please make sure your encoding settings are consistent across all sources. This will help to minimize any potential sync problems caused by framerate differences.

Monitor Audio and Video Sync:
OBS provides real-time audio and video sync monitoring. This allows you to identify and fix any sync issues as they arise.

Benefits of Using OBS and NDI:

Seamless Integration:
NDI integration with OBS makes it easy to bring multiple sources together without sacrificing sync.

Reduced Latency:
NDI offers low latency, ensuring that your audio and video are in sync with minimal delay.

Flexibility:
OBS and NDI can create complex live productions with multiple sources and transitions.

How to Use This Technique in Your Live Productions:

Configure NDI Sources:
Set up your NDI-enabled cameras and microphones in OBS. Could you ensure they send audio and video signals at the correct bitrates and frame rates?

Adjust Delay Compensation:
Fine-tune the audio delay compensation for each source individually. Use the waveform monitor and audio scrubber to accurately align the audio and video waveforms.

Review Sync:
Monitor the audio and video sync in the OBS preview window. If any issues arise, adjust the delay compensation settings as needed.

Conclusion:
Using OBS and NDI together, you can effectively eliminate audio and video sync issues in your live productions. This will ensure a smooth, professional presentation that engages your audience and makes a lasting impression.
