How to make a movie out of images in python
PythonImageVideoScreenshotPython Problem Overview
I currently try to make a movie out of images, but i could not find anything helpful .
Here is my code so far:
import time
from PIL import ImageGrab
x =0
while True:
try:
x+= 1
ImageGrab().grab().save('img{}.png'.format(str(x))
except:
movie = #Idontknow
for _ in range(x):
movie.save("img{}.png".format(str(_)))
movie.save()
Python Solutions
Solution 1 - Python
You could consider using an external tool like ffmpeg to merge the images into a movie (see answer here) or you could try to use OpenCv to combine the images into a movie like the example here.
I'm attaching below a code snipped I used to combine all png files from a folder called "images" into a video.
import cv2
import os
image_folder = 'images'
video_name = 'video.avi'
images = [img for img in os.listdir(image_folder) if img.endswith(".png")]
frame = cv2.imread(os.path.join(image_folder, images[0]))
height, width, layers = frame.shape
video = cv2.VideoWriter(video_name, 0, 1, (width,height))
for image in images:
video.write(cv2.imread(os.path.join(image_folder, image)))
cv2.destroyAllWindows()
video.release()
It seems that the most commented section of this answer is the use of VideoWriter. You can look up it's documentation in the link of this answer (static) or you can do a bit of digging of your own. The first parameter is the filename, followed by an integer (fourcc in the documentation, the codec used), the FPS count and a tuple of the dimensions of the frame. If you really like digging in that can of worms, here's the fourcc video codecs list.

Thanks , but i found an alternative solution using ffmpeg:
def save():
os.system("ffmpeg -r 1 -i img%01d.png -vcodec mpeg4 -y movie.mp4")
But thank you for your help :)
Solution 3 - Python
Here is a minimal example using moviepy. For me this was the easiest solution.
import os
import moviepy.video.io.ImageSequenceClip
image_folder='folder_with_images'
fps=1
image_files = [os.path.join(image_folder,img)
for img in os.listdir(image_folder)
if img.endswith(".png")]
clip = moviepy.video.io.ImageSequenceClip.ImageSequenceClip(image_files, fps=fps)
clip.write_videofile('my_video.mp4')
Solution 4 - Python
I use the ffmpeg-python
binding. You can find more information here.
import ffmpeg
(
ffmpeg
.input('/path/to/jpegs/*.jpg', pattern_type='glob', framerate=25)
.output('movie.mp4')
.run()
)
Solution 5 - Python
When using moviepy's ImageSequenceClip
it is important that the images are in an ordered sequence.
While the documentation states that the frames can be ordered alphanumerically under the hood, I found this not to be the case.
So, if you are having problems, make sure to manually order the frames first.
