In Wowza Video, Quality of Experience (QoE) metrics are key performance indicators that measure various aspects of video streaming from the viewer’s perspective. These metrics help evaluate how effectively video content is delivered and how viewers experience the stream.
Note: Quality of Experience metrics is a premium feature available exclusively to Wowza Video subscribers with an annual subscription. To access this feature for enhanced streaming insights, contact our sales team.
Note: For Wowza Streaming Engine with Wowza Video subscribers, we provide Quality of Experience metrics, including video start time, rebuffer time, and rebuffer count for live streams and stream targets.
The following are the QoE metrics provided by Wowza Video:
- Video start time – The duration it takes for a stream to begin playback after the playback is initiated by the viewer or when the video begins to auto-play. It measures the time from when the user clicks play until the video actually starts. This metric is essential for evaluating user experience, as a shorter video start time signifies a more responsive and seamless viewing experience.
- Rebuffer time – The total duration during which video playback is interrupted to load additional data. This occurs when the video player runs out of buffered content due to network limitations or insufficient bandwidth, leading to pauses in playback.
- Rebuffer count – The total number of times a video stream pauses to buffer during playback. Each time the video player runs out of data and has to stop for additional content to load, it registers a rebuffering event. This metric is important for assessing the quality of the viewing experience.
You can review general analytics for each metric, then drill down to more specific data for each QoE metric.
These metrics are crucial as they directly impact user satisfaction. Shorter video start times and minimal rebuffering lead to a smoother, more seamless viewing experience. Monitoring and optimizing QoE metrics helps video providers deliver high-quality, reliable video streams, enhancing the overall user experience.
