As has been mentioned here before I'm sure, Richelieu and Jean Bart went on exercise together only once in their careers, in January 1956. There are photos of this rare event in some of the books on the class.
However it seems the event was also filmed. Look what I found on the French Ministry of Defence Images website:

No commentary or anything, but the 17 minute long clip contains some lovely aerial and onboard footage of both Richelieu and Jean Bart.
