The 1982 World Championships were held in Argentina. They were won for the second time in a row by the Soviet Union, and both under the coaching of the legendary Vyacheslav Platonov and led by Vyacheslav Zaitsev and Alexander Savin. This tournament was the pinnacle of the Soviet domination of world volleyball. To win the final of a World Championships 15-3, 15-4, 15-5 (#spoileralert) is a special kind of domination.
Here is a YouTube playlist of a variety of videos from the tournament, including the final and both semi finals from a team scouting camera. Not all of the videos are crystal clear, but you can easily understand the game as it was played back then.
