Original series written and shot in South Indian languages, then carried into others without reshooting the performance.
Play with the sound on. The lip-sync is the point, and it is inaudible muted. Films play vertically, as they are made and as they are watched.
One production, two languages. The promo pair opens; the episode pair shows it holds for a full episode, where a sustained dialogue scene has nowhere to hide.
Two further original series, in a different register.
How the performance travels. The comparison reads with the sound off; the breakdown shows the working.
The same method applied to explanatory work, direct to consumer. The Tamil piece is an original, not a localisation.
