These are Scopitones. They're video jukeboxes that were invented in France in the early 1960s and were made from surplus WWII airplane parts. They only lasted a few years. This site has a bunch of Scopitones. The colors were very vivid and the costumes and dancing were somewhat risqué, as evident in one of the most well-known Scopitones: Nancy Sinatra performing Boots.
Check out the Scopitones at 1:58 in the video above.
This is my all-time favorite Scopitone. Whoooooooooaaahhhh!
