What needs to be clarified
Review interval measurement, compare the native stream and export, align frames and assess whether the chosen frame rate supports the reported event duration.
Materials to prepare
- Native recorder file and export with checksums
- Report identifying boundary frames and the interval formula
- Export log, player version and transcoding settings
What to compare
Use verified working copies, preserve originals and document decoding. Compare presentation timestamps, frame durations, repetitions and omissions. Calculate from the supported timeline, checking start/end choices; assess displayed clock time separately from stream timebase and recorder clock offset.
Possible outcome of the analysis
A frame correspondence table, reproducible calculation and plausible interval range may be possible; precise duration may remain unsupported if export discarded essential source timing data.
Limits of the conclusions
Average frame rate need not mean uniform timing. One export proves no editing and cannot restore lost chronology; technical records identify no event participants.
