How to Read This

Green means healthy, yellow means caution, and red means likely problem. Let warm-up finish (30s), then run at least 60s more before trusting the result.

Good Watch Problem

Thresholds adapt to selected quality mode and live playback mode, then update in real time.

Video Data Rate

How much video data is arriving to you right now. Judged against the quality you selected.

Smoothness (FPS)

How smooth motion should look. Higher usually means smoother video.

Safety Buffer

How many seconds of video are ready ahead. More cushion usually means fewer stutters.

Playback Stability (Estimated)

An overall smoothness score for your current viewing session. Higher is better.

Skipped Frames

Cumulative frames your player could not show in time. High totals alone do not always mean an active issue.

Skipped Trend

How quickly skipped frames are increasing. Healthy is close to zero.

Delay From Live

How far behind live your playback is. This is expected to vary by stream settings.

Overall Health Score

A simple summary score of how healthy playback looks right now.
