• moviepy ruining video after combining them

  1er juin 2020, par jjakeryan

  I'm trying to make a program that downloads videos from TikTok and combines all the separate videos into one .mp4 file and moves the final video to a folder on my desktop. I've been able to make it download all the videos and when I watch the separate videos they play fine however when I combine the videos some of the videos are messed up and look like this but the audio is fine.

  



  #slecting all .mp4 files
    video_files = glob.iglob("*.mp4")

    print(video_files)
    clips = []

    for clip in video_files:  # For each mp4 file name
        clips.append(VideoFileClip(clip))  # Store them as a VideoFileClip and add to the clips list

    today = date.today()

    final = concatenate_videoclips(clips)  # Concatenate the VideoFileClips
    final.write_videofile(f"{today}.mp4", codec="libx264")


#moving completed video to folder on desktop
    shutil.move(f'{today}.mp4', '/Users/jacobmarrandio/Desktop/done_videos/')


  



  thanks for any help

  


• Can't save a file in moviepy python

  23 juillet 2023, par user9102437

  I have seen a few questions about this here, but none of them solved the issue for me, so maybe my case is different in some way.

  


  I am trying to achieve a simple result : read a file and write it. Here is the code :

  


  import os
os.environ['FFMPEG_BINARY'] = '/usr/bin/ffmpeg'

from moviepy.editor import VideoFileClip
name = 'test.mp4'

clip = VideoFileClip('./vids/'+name)

clip.write_videofile('./vids/'+name, codec='libx264', fps=30)


  


  This code comes up with an error :

  


  ---> 88     '-r', '%.02f' % fps,
     89     '-an', '-i', '-'
     90 ]
     91 if audiofile is not None:
     92     cmd.extend([
     93         '-i', audiofile,
     94         '-acodec', 'copy'
     95     ])

TypeError: must be real number, not NoneType


  


  You may notice that I have set the environment variable for ffmpeg (I have also changed that in configure_defaults.py). This is because it was suggested in other questions. Also based on them I have run the following commands before running the code :

  


  sudo apt -y update
sudo apt -y install ffmpeg
pip install decorator
pip install moviepy --upgrade
pip install ffmpeg --upgrade


  


  I am using a Debian GNU/Linux 10 (buster) machine, and the versions of moviepy and ffmpeg are 1.0.3 and 4.1.10-0+deb10u1 respectively.

  


  Nothing seems to be helping to solve this. What am I missing here ?

  


• How to utilize multiprocessing and multithreading efficiently to convert 1000s of video files to audio using python in parallel

  8 février 2021, par Sachin Kumar S

  I tried to convert video files to audio using moviepy python package. it works perfectly fine.
However, I have 1500 100MB sized videos and I want to convert all of them to audio files. It takes a lot of time with the standard approach.

  


  Code to convert one video file to audio :

  


  import moviepy.editor as mp
clip = mp.VideoFileClip('file.mp4') 
clip.audio.write_audiofile(r"file.mp3")


  


  I can also use threading to convert multiple files at the same time but I want to utilize multiprocessing and multithreading both to achieve the result most efficiently with less time complexity.

  


  Algo using threading only :

  


  clip1...clip10= make 10 lists with 150 files names from os.listdir()
spawn 10 threads to process 10 files at a time.

t1= Thread(target=convert, args=(clips1))
.
.
.
t10= Thread(target=convert, args=(clips2))


  


  Any Ideas ?
