Example usage demonstrates how to import the library, extract a subclip from 50 s to 60 s, create a centered text title, overlay it on the video, and write the result to a new file:

from moviepy.editor import *
video = VideoFileClip("myHolidays.mp4").subclip(50,60)  # Make the text. Many more options are available.
txt_clip = (TextClip("My Holidays 2013", fontsize=70, color='white')
    .set_position('center')
    .set_duration(10))
result = CompositeVideoClip([video, txt_clip])  # Overlay text on video
result.write_videofile("myHolidays_edited.webm", fps=25)  # Many options...
