write_videofile gets stuck

[rschmaelzle]

Hi,
I am trying to convert a series of about 1000 images (previously created using matplotli and saved) into a movie.

import moviepy.editor as mp

files = [s for s in os.listdir('/Users/Ralf/Desktop/movieplots') if re.match('tmp2',s)]
f2 = files[0:400]  #here i try to select subsets to see whn it crashes, but doesn't seem to be fixed number
clip = mp.ImageSequenceClip(f2, fps=30)

#clipaudio = mp.VideoFileClip(video_filename).subclip(0,34)
#clipaudio.audio.write_audiofile("theaudio2.mp3", fps = 22050)

clip.write_videofile('full_movies_sound.mp4',fps=30, codec='libx264')#, audio=clipaudio) 

I am getting stuck at the last line where the file should be written - it simply stays at 0 forever (but sometimes runs up to a certain number of frames - once or twice also did the job - thus highly unpredictable so far). This is the output.
