Wrong number of frames in .gif file

[avdeevvadim]

Thank you for MoviePy, excellent project :)

I have a problem with correct number of frames in .gif file.
I have a list of images and want to construct an animated .gif file from these pictures. I use ImageSequenceClip and sometimes receive a file with the wrong number of frames.

MWE:

import numpy as np
import moviepy.editor as mpy

frames = 18
fps = 10
height = 10
width = 10
channels = 3

gif = np.zeros((frames, height, width, channels), np.uint8)

gif = list(gif)

animation = mpy.ImageSequenceClip(gif, fps = fps)
animation.write_gif('out.gif')

I expected to get out.gif with 18 frames, but after building file with imageio I received out.gif with 19 frames.
What is the problem here?

I use imageio 1.3, moviepy 0.2.2.11 and Python 3.4.3.

Hello,
I'v met the same problem and believe this problem is not caused by moviepy itself.
Even I specified fps or duration directly in the freeimagemulti.py of imageio 1.3 (which moviepy calls), the same wrong-number-frame problem happened. I am not sure whether this problem is solved in newer version of imageio.

I'm closing this issue because by the sounds of it, the problem reported here was not caused by MoviePy.

If it is/was documented in the imageio repo, please feel free to link any relevant info for future reference/in case others run into similar issues.
