Native Frame Rate Playback
Jun 5, 2023Netflix Technology Blog

Summary
This 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.
