Download Handout from Video Quality Metric Session

I had a 45-minute session at Streaming Media West 2019 entitled HOW-TO: Fine-Tuning Your Encoding With Objective Quality Metrics

You can download the handout here. This version is about 200 MB because it contains three video demonstrations of the SSIMPLUS VOD Monitor and several other videos, but you’ll need Flash installed to run them (it’s PowerPoint, not me). You can download a version without the videos here; it’s only 4 MB.

Here’s the session description. When the video is available I’ll add it below.

Choosing the number of streams in an adaptive group and configuring them is usually a subjective, touchy-feely exercise, with no way to really gauge the effectiveness and efficiency of the streams. However, by measuring stream quality via metrics such as VMAF, SSIMPlus, and others, you can precisely assess the quality delivered by each stream and its relevancy to the adaptive group. This presentation identifies several key objective quality metrics, teaching how to apply them using commercial and open-source tools and how to use them to fine-tune your adaptive bitrate ladders and encoding settings.

For more information on computing and using video quality metrics, I have a video course with over 3 hours of video instruction. For more on the course, click the course image below, or click here.
