[VBR vs CBR] Which One Do You Prefer for Video Encoding/Transcoding?

Author by Kevincy Berel

Jan 17, 2020

VBR vs CBR are widely used in the vigorous development of digital media nowadays, However, due to their different characteristics, the application and usage also vary. Therefore, in order to ensure a reliable, convenient and efficient conversion, this article will vulgarly explain the difference between CBR and VBR and how to convert VBR video to CBR and vice versa.

CBR means Constant Bitrate, the bit rate remains constant in a fixed value during the video encoding, e.g. 3000kbps, which means the video will be encoded in 3000kbps from beginning to end. Based on this, CBR is the most effective solution for video streaming. Think about it, if there is the limited bandwidth on some streaming platforms that matters the maximum bit rate, CBR encoding will take full advantage of the capacity to reach the best quality. However, CBR is not suitable for local multimedia storage, because CBR will result in insufficient bitrates to encode complex video scenes (thus leading to quality degradation), while some bitrates will be wasted on simple scenes.

As opposed to CBR, VBR is the abbreviation of Variable Bitrate. As its name implies, the video bit rate can vary with the complexity of the image, so the video encoding in VBR mode is very efficient with high quality but smaller file size. That is to say, during a VBR video encoding, the video bitrate will dynamically go higher or lower based on the changes of different parts, increased for complex scenes and decreased for simple scenes, which will save storage space. So VBR is suitable for local multimedia storage rather than streaming. VBR encoding seems pretty good, huh? Not really, this encoding process may take more time to encode, and you may run into incompatibility issue on some players & devices by the lack of ability to decode VBR video files.

What Are the Differences between CBR and VBR?

If you're bored with the above obscure content, go straight to the summary below.

Simple Guide for Switching CBR or VBR Encoding

Load Source Video Files

Before start, please free downloadfree download the software.

Step 1 - Load Source Video Files

Launch HD Video Converter Factory Pro, go to Converter module. In the new intuitive window, import your video files via Add Files button. Alternatively, simply drag them into the interface.

Switch CBR or VBR Mode

Step 2 - Switch CBR or VBR Mode

Expand the Output Format list on the right side and select one desired profile from 500+ preset formats and devices. Then press the Parameter settings button to open the Settings window, here you can select video encoder, modify resolution and change video bit rate as well. You are able to select one optimized CBR option from the Smart Fit drop-down list, or press the nearby Customize button to manually input the specific bit rate. In contrast, to enable VBR mode, you have to check the box alongside the VBR mode, then you can move the slider to High quality below. Click OK and go back to the main interface.

Start Video Conversion

Step 3 - Start Video Processing

Finally, navigate to the inverted triangle on the bottom of the program and specify a destination folder to save your converted file. Then hit the Run button to start the conversion between VBR and CBR mode.

Tips: This program also allows you to compress video, trim/merge/watermark video at full hardware-accelerated speed. Some bonus features are waiting for you to discover.

At last...
