• Getting "TypeError : must be real number, not NoneType" whenever trying to run write_videofile to a clip in moviepy

  9 novembre 2024, par Sato

  Example code :

  


  from moviepy.editor import *
clip = VideoFileClip('video.mp4')
clip.write_videofile('video2.mp4', fps=30)


  


  After showing the following messages, showing that the video is being built and written,

  


  Moviepy - Building video video2.mp4.
Moviepy - Writing video video2.mp4


  


  The following error message occurs :

  


  Traceback (most recent call last):&#xA;  File "<stdin>", line 1, in <module>&#xA;  File "C:\Users\User\Anaconda3\lib\site-packages\decorator.py", line 232, in fun&#xA;    return caller(func, *(extras &#x2B; args), **kw)&#xA;  File "C:\Users\User\Anaconda3\lib\site-packages\moviepy\decorators.py", line 54, in requires_duration&#xA;    return f(clip, *a, **k)&#xA;  File "C:\Users\User\Anaconda3\lib\site-packages\decorator.py", line 232, in fun&#xA;    return caller(func, *(extras &#x2B; args), **kw)&#xA;  File "C:\Users\User\Anaconda3\lib\site-packages\moviepy\decorators.py", line 135, in use_clip_fps_by_default&#xA;    return f(clip, *new_a, **new_kw)&#xA;  File "C:\Users\User\Anaconda3\lib\site-packages\decorator.py", line 232, in fun&#xA;    return caller(func, *(extras &#x2B; args), **kw)&#xA;  File "C:\Users\User\Anaconda3\lib\site-packages\moviepy\decorators.py", line 22, in convert_masks_to_RGB&#xA;    return f(clip, *a, **k)&#xA;  File "C:\Users\User\Anaconda3\lib\site-packages\moviepy\video\VideoClip.py", line 300, in write_videofile&#xA;    ffmpeg_write_video(self, filename, fps, codec,&#xA;  File "C:\Users\User\Anaconda3\lib\site-packages\moviepy\video\io\ffmpeg_writer.py", line 213, in ffmpeg_write_video&#xA;    with FFMPEG_VideoWriter(filename, clip.size, fps, codec = codec,&#xA;  File "C:\Users\User\Anaconda3\lib\site-packages\moviepy\video\io\ffmpeg_writer.py", line 88, in __init__&#xA;    &#x27;-r&#x27;, &#x27;%.02f&#x27; % fps,&#xA;TypeError: must be real number, not NoneType&#xA;</module></stdin>

  


  This occurs whenever I try to perform write_videofile to any kinds of clip in moviepy. It is strange since the exact same code worked for me yesterday, but suddenly not anymore today. Are there any suggestions what the cause is and how to resolve this ?
