Native Frame Rate Playback

1 post · Jun 2023

What this trail covers

Netflix is evolving its playback experience by implementing native frame rate playback across various consumer streaming devices. This involves leveraging device capabilities and developing in-app solutions to mitigate visual artifacts like judder, which occur during frame rate conversions. The goal is to maximize member immersion by delivering a smooth, glitch-free viewing experience, adapting to different HDMI standards and device limitations.

  1. Native Frame Rate PlaybackThis post details the problem of judder caused by frame rate conversion (FRC) in streaming devices, where content's native frame rate is converted to the HDMI output frame rate (typically 50/60Hz). It outlines three solutions: 1) Matching HDMI frame rate to content native frame rate (with potential screen blanking on older HDMI standards), 2) Utilizing HDMI 2.1's Quick Media Switching (QMS) for seamless transitions without blanking, and 3) Implementing in-app frame rate manipulation by adjusting presentation timestamps to minimize judder. The Netflix application dynamically selects the best approach based on device capabilities and user preferences.
