What Is Video Bitrate Mode?

Video bitrate mode refers to the method used to encode video data and determine the amount of data transmitted per second. There are two primary modes:

  • Constant Bitrate (CBR): CBR maintains a fixed bitrate during video compression. This ensures consistent network traffic, making it suitable for stable network environments. However, during scenes with high complexity, CBR may reduce image quality to maintain the fixed bitrate. It's ideal when network bandwidth is stable but may struggle when bandwidth fluctuates.
  • Variable Bitrate (VBR): VBR dynamically adjusts the bitrate based on the scene's complexity. This method provides higher video quality in complex scenes, but it requires more bandwidth consistency. If the network's bandwidth is insufficient, you might experience buffering or playback issues.

Considerations When Setting Up Video Bitrate

When setting up the video bitrate on your Reolink device, consider these factors:

  • Network Stability: If your network experiences frequent fluctuations, VBR might provide a better viewing experience as it adapts to the available bandwidth.
  • Storage Capacity: CBR uses a fixed amount of storage space, which is easier to predict and manage compared to VBR.
  • Video Quality & Resolution Requirements: To maintain a good video bitrate for 1080p or higher resolutions, preserving video quality is crucial. For applications like 4K video bitrate setups, VBR is often preferred because it reduces compression artifacts during rapid scene changes, ensuring better visual fidelity.

How to Set Up Video Bitrate for Streaming

Configuring the right video bitrate for streaming is essential to maintain both quality and performance. Below are step-by-step instructions to set up video bitrate modes on Reolink devices, including the Reolink App, Client, web browser, and NVR.

  • Via Reolink App

    Step 1. Tap gear icon in the upper right corner and navigate to Camera Display > Stream.live view duostream settings
    Step 2. Choose Bitrate Mode, where you can select either Constant Bitrate or Variable Bitrate.
