When the offer changed from 20 to 30 percent off, the editor used lip sync to fit the new line to the spokesperson's mouth, with her written approval on file.
In the illustration
Sound runs on one wheel and picture on the other; the stylus reads each syllable on the track and redraws the mouth in the frame beside it until every shape matches its sound.
Use lip sync in your creative tool to match the presenter's mouth to the approved Spanish voiceover for the 15-second cut, and flag any frames where the jaw or teeth blur.
