Read which object owns the number
A media inspection report can contain information for the enclosing format and information for individual streams. Those are different objects. Before comparing two duration numbers, label each one as container, video, audio or another track, and retain its units. A player’s rounded time display is another observation. It should not automatically be equated with every detailed value printed by a diagnostic tool.
Work through a hypothetical example
Suppose a local report shows a format duration of 600.08 seconds, a video track of 600.00 seconds and an audio track of 600.08 seconds. The difference between the latter two is 0.08 seconds. That arithmetic alone is not evidence that eight seconds of an episode disappeared, and it does not locate a playback fault. First check the decimal point, units and whether the application rounded its visible total to ten minutes.
Use content observations as well
If the viewer reports a cut ending, record the final audible and visible content and compare the same authorised file in another documented player. A short duration discrepancy and a missing final scene are different evidence. Conversely, equal duration values cannot prove that the correct edition or complete programme was supplied. A nominally ten-minute test clip can still contain the wrong material, so keep identity separate from timing metadata.
Preserve uncertainty in the report
ffprobe provides format and stream sections, but available fields depend on the input. Do not manufacture a track duration when the report lacks one. A useful support note might say that the format reports a total, one stream has no duration field, and playback stops at a recorded position. That gives the publisher a specific case to investigate without converting one metadata difference into a universal diagnosis.
