Private beta · Dubbing sync QC

Catch sync drift before delivery.

DubMetric compares a reference master with a dubbed version and surfaces timing problems that deserve human review — global offset, progressive drift and suspicious local ranges.

Workflow

From two masters to a reviewable signal.

Minimal input. Focused output. DubMetric narrows attention to synchronization issues without pretending to replace professional QC.

01

Upload

Reference master + dubbed version.
Two source files. One comparison.
02

Analyze

Measure offset, drift and suspicious ranges.
Timing evidence is surfaced automatically.
03

Review

Inspect timecodes and export the QC report.
PASS / WARN / FAIL / INCONCLUSIVE.

What it checks

Three failure modes. One review surface.

Each check answers a different synchronization question and returns evidence that a human reviewer can verify.

Global Offset

Detect when the dubbed track is consistently early or late against the reference.

+150.000006 ms

Progressive Drift

Identify alignment that gradually moves away from the reference over time.

+300.009 ms

Local Sync Anomalies

Highlight suspicious time ranges that deserve closer editorial review.

Evaluate DubMetric on a controlled synchronization case.

We are inviting a small number of dubbing studios and localization teams to evaluate the private beta using demo, synthetic or non-confidential material and share direct workflow feedback.
