Variable Bit Rate (VBR)

VBR or Variable Bit Rate is a term used in computing and telecommunications that relates to the bitrate used in video or sound encoding. VBR files differ the amount of output data per time segment contrasted with constant bitrate (CBR). While a smaller amount space is allocated to less complex segments, VBR allows a higher bitrate (Hence needs more storage space) to be allocated to the more complex segments of media files. The average of these rates can be calculated to produce an average bitrate for the file.   

VBR encoding regulates the data rate down and to the upper limit you set, depending on the data required by the compressor. This means that during a VBR encoding process the bitrate of the media file will dynamically decrease or increase based on the media files bit rate requirements. VBR produces the most favorable results even though it takes longer to encode as the quality of the media file is superior. Most commonly, VBR is used for http delivery of video content.  

Also VBR encoding, a technique that dynamically adjusts the bitrate during the encoding process, offers significant advantages for live audio streaming service. By intelligently allocating bits based on the complexity of the audio content, VBR ensures that the highest possible audio quality is delivered to listeners, even in challenging network conditions.

Introducing TrueComply: Scaling Video Compliance with AI Automation
Introducing TrueComply: Scaling Video Compliance with AI Automation

Video compliance has always been a critical requirement for broadcasters—and today, OTT platforms, streaming services, and enterprise video teams face the same challenge at a much larger scale.

Every video must pass compliance checks before release. And whenever regulations or platform policies change, entire video libraries need to be revalidated. Manual reviews make this slow, expensive, and error-prone, often delaying launches and increasing operational risk.

 

This webinar introduces TrueComply, an AI-powered compliance engine that automates video reviews, validations, and required compliance edits—helping teams keep content compliant continuously and at scale.

What this Webinar will Cover:

 

  1. Why Video Compliance Is Breaking at Scale
    The limitations of manual reviews, spreadsheets, and region-by-region workflows.

  2. How AI Is Transforming Compliance Operations
    Using automation to flag risks, enforce rules, and reduce dependency on human moderation without compromising accuracy.

  3. Inside TrueComply: How It Works
    A practical demo of how TrueComply centralizes compliance management, automates checks, creates detailed reports, and scales across regions and content types.

  4. Real-World Use Cases
    How video businesses can apply AI-driven compliance to real publishing workflows.
