Make Sense of a Complex Aspect of Encoding

Streaming Learning Center’s Jan Ozer discusses the choices available to video encoders between using constant bit rate or variable bit rate for streaming videos.

He writes, “The recommended bit rate control technique for VOD files produced for adaptive streaming is one of the most fundamental decisions encoding professionals make, but in my view also one of the most confusing. If you scan the white papers on the topic, most recommend using constant bit rate (CBR) encoding to simplify the stream selection process. On the other hand, if you survey the techniques actually used by streaming professionals, most seem to prefer constrained VBR.”
