Designed for authentic Spanish video
The extension is focused on RTVE Play rather than generic page translation. It works with the player’s caption timing so the original and translated lines stay connected to the scene you are watching.
It is useful for Spanish learners, bilingual households, and viewers who want translation support without replacing the original captions.
