✦ WHY THIS WORKFLOW
Editing lip movements on real footage is far more convincing than full synthetic avatars. MuseTalk runs in real time and supports multilingual phoneme alignment.

Perform **Isochronous Dubbing Adaptation** on the timestamped transcript below:
1) Translate each line into natural spoken target language;
2) Match the syllable count and speaking duration within ±0.3 seconds of the original line so body gestures stay aligned;
3) Mark stressed words that coincide with head nods or hand gestures.
