  My intention would be to get at the same time, picture1.jpg, picture2.jpg, picture3.jpg to video format such as picture1.mp4, picture2.mp4, picture3.mp4.

  I am currently using Mencoder and Linux bash code mencoder mf: //*.jpg -mf w = 1366: h = 768: fps = 6/60: type = jpg -ovc copy -oac copy -o images.mp4. But this command makes all the images into one video file (images.mp4).

  Can I do it with mencoder or ffmpeg ?
  My linux bash coding skills are basic.

  I’m trying to render a animation.ArtistAnimation object into a 24 fps video file in format mp4.

  I have search about and I reached this. However, even after compiling ffmpeg I get this error message :

  C:\Users\trite\OneDrive\Documentos\MusiTex\Python\venv\Scripts\python.exe 
  
  "C:/Users/trite/OneDrive/Documentos/MusiTex/Python/venv/Saving Animation.py"

      return self.avail[name]
  
  KeyError: 'ffmpeg'
  
  
  
  During handling of the above exception, another exception occurred:

      'Requested MovieWriter ({}) not available'.format(name))
  
  RuntimeError: Requested MovieWriter (ffmpeg) not available
  
  
  
  Process finished with exit code 1
  
  </module>

  What is the problem with ?

  I would really appreciate if you can help me. Actually, if there is other ways to saving/render this kind of object into a video file (preferably mp4) I will be delighted to hear them.

  Thank you very much

• MoviePy Error : The system cannot find the file specified

  4 juillet 2017, par JohnSmithy1266

  I’m getting the error in the title when trying to run the example code below on Windows 10/Python 3.6.1/Sublime Text Editor 3. I made sure to set my MAGICK_HOME environment variable to point to where I manually installed ImageMagick. I made sure to only have 1 version of ImageMagick installed. I made sure FFMPEG, Numpy, imageio, Decorator, and tqdm were all installed.

  Yes, the file "vidclip.mp4" exists. The desired behavior here is to simply clip the video and add text to the center as per the example on the github page, i.e. to simply run the code successfully.

  Does anyone know what might be wrong ?

  Example code from github :

  from moviepy.editor import *
  
  
  
  video = VideoFileClip("vidclip.mp4").subclip(7,64)
  
  
  
  # Make the text. Many more options are available.
  
  txt_clip = ( TextClip("Ken Block who?",fontsize=70,color='white')
  
               .set_position('center')
  
               .set_duration(10) )
  
  
  
  result = CompositeVideoClip([video, txt_clip]) # Overlay text on video
  
  result.write_videofile("vidclip_edited.webm",fps=25) # Many options...
