Lip sync is good on some inputs, described as more precise in one case and good for slow to medium speech, but it becomes weaker on fast speech with slight delay, sync inconsistencies, and slightly off audio-video alignment.

What was measured
Lip Sync Accuracy

Does the dubbed audio visually match lip movements in the original video?

decisive for this rankingtransformation

The ranking is specifically about lip sync, so visual alignment of speech to mouth movement is a core success criterion. (3 of 3 judges)

What was given, what came back

Input — what we sent
No input — this is a capability finding
The observation is about the tool itself rather than one test input, so there is nothing to show on this side by design.
Output — unretouched
No output artifact
The verdict rests on the tester's written observation alone — no file was captured for this cell.
