Examples of using the python library MoviePy
Summarizing a video
from moviepy.editor import *
clip = VideoFileClip("CC501_hypercard.ogv")# .subclip(10, 15)
x = clip.subclip(10, 15)
# x.write_videofile("x.webm")
p = []
# ADD STUFF TO OUR PLAYLIST
for i in range(0, int(clip.duration), 60):
print "i am editing from", i, "to", i+1
x = clip.subclip(i, i+1)
p.append(x)
# SAVE THE MOVIE
n = concatenate_videoclips(p)
n.write_videofile("loop.webm")
Cutting with subtitles (videogrep)
Here's a file that should be called "srt.py":
