Description
Estimate transcript-to-audio sync drift in seconds per hour from the change in alignment offset over the elapsed interview duration.
Transcript Sync Offset Drift Seconds per Hour Estimator: Estimate transcript-to-audio sync drift in seconds per hour from the change in alignment offset over the elapsed interview duration.
When to use Transcript Sync Offset Drift Seconds per Hour
Use the result while planning ingest, digitization, quality control, reporting, or preservation work where the stated rule needs to be repeatable and reviewable.
- Start offset
- Sync offset in seconds at the reference point.
- End offset
- Sync offset in seconds at the later checkpoint.
- Elapsed hours
- Interview playback hours between the two checkpoints.
How Transcript Sync Offset Drift Seconds per Hour works
Estimate transcript-to-audio sync drift in seconds per hour from the change in alignment offset over the elapsed interview duration. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Drift per hour
- Estimated drift in seconds per hour of playback.
- Total drift
- Total offset change between the checkpoints.
Limitations and assumptions
- Repository policies, format profiles, equipment capabilities, and descriptive standards vary. Preserve the source value and record the rule version instead of treating this utility as an authority-record or preservation-system validator.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Complement the calculation with format validation, fixity checks, provenance records, and human review. For policy decisions, apply the profile adopted by the repository rather than an undocumented local convention.
