no, there is no footage of charlie parker together with lester young. the film you mean is norman granz´ promotion film "improvisation" from his j.a.t.p. group in the fall of 1950. prez is on two numbers, "pennies from heaven" and "blues (up-tempo)" together with harry edison, bill harris, flip phillips, hank jones, ray brown, buddy rich and ella fitzgerald. this movie forms a whole with a performance of coleman hawkins and bird with jones, brown and rich (at gjon mili´s not sound proofed photo studio), playing "ballade" and "celebrity". but prez and bird together on film, unfortunately not! (and i don´t know what 52 seconds means the other). the other with sound is the famous "hot house" with dizzy. and than there is only one more silent from sweden, november 21. 1950.
