Name And Composer Of A Music In German (?)

I wonder whether anyone can help with this....
Underneath is a link to a video from Portuguese Television for seasons greetings.
At 0:21, a hymn in german starts. Does anyone know its composer and name of the hymn? I suppose it's for new year's greetings, but I really cannot say.
Thank you!
