Following the helpful suggestions given, I am attempting to write a 
python program to automatically rename the movie files for me.  However, 
I have gotten stuck.  Here is the code.

import os
import re
with os.scandir() as i:
     for entry in i:
         if entry.is_file():
             filename = entry.name
             basename, ext = filename.rsplit('.', 1)
             print(basename,ext)
             basenameregex = 
re.compile('^([^.]+(?:\.[^.]+)*)\.(\d{4})\.(\d+p)')
             title = re.split(basenameregex, basename)
             print(title)
             movietitle = title[1].replace('.', ' ') # replace periods 
with spaces
             #movietitle = re.split('^([^.]+(?:\.[^.]+)*)',title)
             yearregex = re.compile('\.(\d{4})')
             year = re.search(yearregex, title)
             resolutionregex = re.compile('\.\(d+p)')
             resolution = re.search(resolutionregex, title)
             print (movietitle, year, resolution)

This program gives the following error messages when run.

/home/john/bin/renamemoviefiles.py:9: SyntaxWarning: invalid escape 
sequence '\.'
   basenameregex = re.compile('^([^.]+(?:\.[^.]+)*)\.(\d{4})\.(\d{3}p)')
/home/john/bin/renamemoviefiles.py:14: SyntaxWarning: invalid escape 
sequence '\.'
   yearregex = re.compile('\.(\d{4})')
/home/john/bin/renamemoviefiles.py:16: SyntaxWarning: invalid escape 
sequence '\.'
   resolutionregex = re.compile('\.\(d+p)')

I can't seem to find my error.  Suggestions and improvements welcome.
