Video latency is measured as the delay between the time a video stream is requested by the viewer and the time the video stream is initiated. Networks that deliver significantly lower delays are termed low-latency networks. Optimizing for negligible delays and low latency streaming leads to better audience retention and improved end-user experience.
The time a video player takes to initialize and be ready for inputs from the viewer to start video playback is tracked as the player start-up time.
Nothing is more off-putting than a gray box loading on a webpage without video playback. Longer player start-up time invariably leads to a drop in audience retention. By tracking this metric, you can:
The time a player takes when a viewer clicks the play button for the first time to the time the first frame of the video is shown to a viewer is tracked as video start-up time.
Viewers start abandoning videos if it takes more than two seconds to start. Tracking video start-up time helps optimize and retain viewers.
The total time spent waiting for playback to resume after the viewer seeks a new location on the video is measured as seek latency.
A single buffer event can lead to a 39% drop in viewers. Optimizing for seek latency is crucial to delivering a better video experience for your end-user. Track seek latency to:
