These shots are more likely from the early 70s. The Hotel Duna InterContinental (today the Budapest Marriott Hotel), from where the shots were taken, was only opened in 1970 and you can also see a Lada 1200 (VAZ-2101) driving by, this car did not exist before 1970 either. However, there is still tram traffic on the Elizabeth Bridge, a service that was discontinued in winter of 1972/73.
