In the late 1960s and early 1970s the Hamburg State Opera cooperated with Polyphon and NDR to make a series of thirteen films for television of assorted operas. They are all available as a boxed set called Cult Operas of the 1970s but one or two of them are also available separately. One such is a 1968 recording of Weber’s Der Freischütz. It was directed for film/TV by Rolf Liebermann and recorded in the studio using the HSO’s stage production. I think the action is lip synched to a pre-recorded soundtrack (normal practice at the time) but I’m not sure.
