Video: Video-Evaluation Best Practices: Testing & Optimisation Techniques

In this webcast, AWS Elemental dives into a topic other companies don’t discuss: The video encoding techniques some vendors use to sway judgment during proof-of-concept demos.

Improve your discerning eye and your analysis acumen, and obtain essential knowledge:

  • Methods and best practices for evaluating video quality
  • Examples of scenes which look totally different, but have the same metrics score
  • Important considerations for accurate evaluation of video results
  • Subjective vs. Objective results
  • How encoder settings affect output and how you can fine tune them for the best results
  • What is Adaptive Quantization and how can it improve your video output quality
  • Encoding techniques that impress in shootouts but might not be practical in production

Video encoding comparisons should inform, not fool. Learn what you need to know, before you start the process.

Video: Streaming at 250 kbps – raise your expectations


Megha Manohara discusses Netflix’s ongoing efforts to reduce the bitrate of movies whilst maintaining their enjoyability showing their success right down to 250kbps.

As a Senior Software Engineering on Video Algorithms, Megha’s talk focuses on the research and implementation challenges of Dynamic optimizer – an innovative shot-based encoding tool that raises the perceptual quality of streams at bitrates as low as 250kbps. Visiting VMAF, PSNR and other metrics on the way, this talk gives great ideas on reducing bitrate and measuring success.
