Tips to Improve Live Streaming Quality

Introduction

Live streaming quality is crucial to delivering an engaging and professional viewer experience. If you or your viewers notice low video resolution, buffering, or lag, it could be due to several factors. In this help article, learn why the live stream quality may drop and how you can enhance it.

Common Reasons for Low Live Streaming Quality

Multiple variables influence streaming quality, both from the broadcaster's end and the viewer’s end. Below are the primary factors:

1. Internet Speed and Stability

• Upload speed affects the broadcaster's ability to send a high-quality stream.
• Download speed impacts the viewer’s ability to receive and play the stream without buffering.
• Unstable connections can lead to dropped frames or resolution downshifting.

Recommendation: At least 5-10 Mbps upload speed is recommended for streaming in 720p or higher.

2. Input Feed Quality

• A poor-quality camera or a low-resolution source feed directly limits the maximum output quality.
• Improper lighting or unbalanced audio can further degrade perceived quality.

Recommendation: Use HD or 4 K-capable input devices and test your feed before going live.

3. Adaptive Bitrate Streaming (ABR)

Our platform uses adaptive bitrate streaming, meaning the viewer receives a version of the stream based on their current internet speed and device capability.

• If a viewer's internet slows down, the stream automatically switches to a lower resolution.
• This ensures smoother playback but may result in temporarily lower quality.

4. Streaming Settings Configuration

Incorrect or overly aggressive encoding settings, like high bitrate, resolution, or frame rate can cause performance issues on both the broadcaster and viewer ends.

Recommendation: Use a balance between quality and performance. For example:

• 720p @ 30fps:5–4 Mbps bitrate
• 1080p @ 30fps: 4–6 Mbps bitrate
• 1080p @ 60fps: 6–8 Mbps bitrate

5. Device Limitations

Older devices or browsers may not handle high-resolution video streams efficiently, leading to lag or automatic quality downgrade.

Recommendation: Test across devices and ensure you're using updated browsers and hardware.

Tips to Improve Live Streaming Quality

1. Use a Wired Internet Connection
   Wi-Fi can fluctuate. A wired Ethernet connection is more stable and provides consistent upload speeds.
2. Optimize Your Encoder Settings
   Use recommended settings for resolution, frame rate, and bitrate depending on your content type and audience bandwidth.
3. Monitor Your Input Feed
   Ensure that the camera or source input is clear, well-lit, and in focus.
4. Close Background Applications
   On both broadcaster and viewer devices, background apps can consume bandwidth and processing power.
5. Start the Server Early
   If using our on-demand live stream model, ensure the server is started at least 2 minutes before the broadcast to allow proper setup and encoding.
6. Encourage Viewers to Check Their Network
   Viewers with slow or unstable internet may receive a downgraded stream. Recommend switching to a better connection or a different device if necessary.
7. Use a Quality CDN (Content Delivery Network)
   Our platform leverages a robust CDN to ensure quick and efficient delivery from the origin server to global edge locations.
