import win32com.client
import time

powerpoint = win32com.client.Dispatch("Powerpoint.Application")
try:
    # Attempt to open file
    #presentation = powerpoint.Presentations.Open(FileName='lol.pptx', WithWindow=False)
    presentation = powerpoint.Presentations.Open(FileName=r'C:\Users\tomd\Development\PPPTX2MP4\lol.pptx')
except:
    # If file cannot be found
    print('File cannot be found')
    exit

try:
    # May need a few other parameters as well
    presentation.CreateVideo(r'C:\Users\tomd\Development\PPPTX2MP4\out.wmv')
