set them to translate directly
thanks for the suggestion. If there is any explanation to get YouTube to translate directly, let us know.
Using the 2-device methos with Google Translate helped to get a sense of the presentations today.
In the Youtube video player, first click the "CC" icon to enable captions. Then click the gear icon (settings), choose "Subtitles/CC", choose "Auto-translate", and then choose your target language.
