Lesson of the Week: Why BD-Rate is a Poor Predictor of Real-World Bandwidth Savings

BD-Rate computations are a valuable metric when comparing theoretical codec performance. But just because they prove that HEVC is 40% more efficient than H.264 doesn’t mean that you’ll save 40% of your bandwidth if you switch to HEVC.

This 6-minute video lesson explains why and suggests a better alternative for estimating real-world benefits. I include a link to the presentation below.
