DIAGNOSTIC RESULT
Observed signal state
No observation yet
Start the local check to create eight plainly classified diagnostic results. Permission status is not inferred before you act.
Deterministic thresholds
Visible engineering defaults—not validated broadcast tolerances.
- Black tendency
- Mean luma ≤ 8% in ≥ 80% of sampled frames
- Freeze tendency
- Pixel delta ≤ 1% for ≥ 1500 ms
- Video continuity
- Warning when browser sample gap > 750 ms
- Silence tendency
- RMS < 0.01 in ≥ 80% of windows
- Clipping tendency
- Peak ≥ 0.99 in ≥ 1% of windows
- Audio continuity
- Warning when browser analysis gap > 500 ms
