The Rythmo Band: Dubbing's Best-Kept Secret

In 1949, French dubbing studios invented the "rythmo band." It's a strip of scrolling text that guides voice actors' lip-sync timing, not just their lines. In this episode, Margaux Christie, Product Manager at Voxdub, walks us through three parts. First, the history. Where the rythmo band came from, and how it spread across the French-speaking dubbing world (France, Belgium, Switzerland, francophone Africa, Quebec with a slightly different path) Second, dubbing today. The shift from hand-inked film to scrolling text in modern software. And how AI fits in, not to generate voices or replace actors, but to speed up the mechanical groundwork: transcription, draft translation, scene detection, audio cleanup. That frees up time for what still can't be automated, adapting the translation, personalizing the performance, getting lip-sync exactly right. Third, the next five years. As AI capabilities grow, does the core bottleneck, rhythm and lip-sync precision, stay a human craft, or start to shift?
