#Python 🐍 – concatenate video and add blur effect 🎦 using moviepy and scikit-image

Hi !

Today I’ll share another cool sample using moviepy, and I’ll also use scikit-image to add some extra effects.

This one is again based on the cat videos, and perform this steps:

Using the cat video, open 3 video objects with different segments: 1-2 seconds, 2-4 seconds, 4-6 seconds
Resize each video to be smaller
Apply a blur effect to the 2nd video
Concatenate the 3 videos
Export the output to Gif

The code is super simple:

	from moviepy.video.compositing.concatenate import concatenate_videoclips
	from skimage.filters import gaussian
	from moviepy.editor import VideoFileClip, clips_array, concatenate_videoclips

	def blur(image):
	""" Returns a blurred (radius=4 pixels) version of the image """
	return gaussian(image.astype(float), sigma=4)

	# open video and resize to 460
	clip1 = VideoFileClip("cat1.mp4").subclip(1,2).resize(width=200)
	clip2 = VideoFileClip("cat1.mp4").subclip(2,4).resize(width=200)
	clip3 = VideoFileClip("cat1.mp4").subclip(4,6).resize(width=200)

	# blur clip 2
	clip2_blurred = clip2.fl_image( blur )

	# final
	final_clip = concatenate_videoclips([clip1, clip2_blurred, clip3])
	final_clip.write_gif("blurdemo.gif")

Super, easy. It and the output is a 2MB gif file.
