Use a Replace method with a regular expression...
Replace: .*_([^_]*)_[^_]*_[^_]*$
With: \1
Use regular expressions
eg for "ActorA_ActorB_ActorC_ExampleMovieTitle_4096x2160_24fps.mp4":
".*_" matches a string of as many characters as possible ending with "_" ie "ActorA_ActorB_ActorC_"
"([^-]*)" matches any string of any characters not including "_" and saves the result as \1 ie "ExampleMovieTitle"
"_[^_]*" matches "_" followed by a string of any characters except "-" ie "_4096x2160"
"_[^_]*&" as previous but must be at the end of the filename ie "_24fps"
