I assume the film dates back to around 1974-75 with the transition to colour as well as Gough Whitlam making Advance Australia Fair the national anthem around that time before God Save The Queen was reinstated by the time Malcolm Fraser was in office. Of course Advance Australia Fair was brought back by Bob Hawke in 1984. Hence off air recordings of Australian sign offs pre 1984 using that film.
That NBN one i posted from 1991 looks like they eventually replaced the Navy one with one produced in house basically made of footage of the Newcastle harbour
The tape/film was probably worn out by that stage. It’s actually better because it’s nice and slowed down. Remember, it was played in the middle of the night when you wanted people to go to sleep.
The other national anthem clip that was used by multiple stations was this one, as used by GMV (and I’m guessing BTV) and SES (and RTS) - stretching into the 90s and early 2000s as WIN SA. IIRC, another station may have used this vision but changed the instrumental OR used a vocal.
A second version of the clip had different scenes and used a different instrumental. This one was from TNT pre-Tas TV days but IIRC another station used it too. https://www. youtube .com /watch?v=6Xvo0L_oUWQ
ITQ used that 2nd version but inserted their own music - I don’t know the song.

As for who produced it - maybe someone can shed light on it? Maybe someone produced it for multiple stations and they took them up on it?
