Lip sync is good for slow to medium speech, but fast instruction segments show a slight delay and fast speech parts show a noticeable audio-video mismatch.
What was measured
Lip Sync Accuracy
Does the dubbed audio visually match lip movements in the original video?
decisive for this rankingtransformation
If the dubbed audio does not match the on-screen mouth movements, the core purpose of video translation with lip sync has failed. (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.
