Upcoming Webcast: Intro to QVBR, Quality-Defined Variable Bitrate Control

 

QVBR

If the most important characteristic of encoded video is quality, a simple and certain way to achieve it is through quality-defined variable bitrate (QVBR), a new rate control mode designed to deliver constant video quality and waste zero bits in the process. When your video quality requirements are high, but your bandwidth budget is low, QVBR fulfills both needs.

This webcast will give you an introduction to QVBR and a demonstration of how it works, and will cover QVBR’s benefits including:

  • Save costs: Less transfer with CDN egress and less storage, saving up to 50% or more, depending on video content
  • Improve video quality (VQ) consistency: Maintain uniformity across content, and use a higher peak bitrate only for complex scenes
  • Easy to operate: No more content-based bitrates. Instead, just set a fixed video quality level and a max bitrate (according to connectivity and device requirements) and let the encoder do the rest
  • Multi-codec support: Use with AVC codec, or the HEVC codec for even greater compression efficiency
  • Start using it now: Available now in AWS Elemental Live software, with no additional licensing fees
