• Can't write video using moviepy. output format error

  23 décembre 2022, par Ronnie Kisor

  I'm trying to concatenate videos in each folder so that I get one video in each folder instead of multiple short ones. This is an external USB drive if that matters.

  


  My code seems to iterate over the files as expected, but I keep getting this error after the audio is written, during the "writing video" action, I believe : b"[NULL @ 000002a8340ae640] Unable to find a suitable output format for 'D:\\taxes\\folder\\test'\r\nD:\\taxes\\folder\\test: Invalid argument\r\n"

  


  I haven't found a way to force an output format yet. Any thoughts ?

  


  import os
from moviepy.editor import *

startingDir = r'D:\taxes'

avoid = ['0incomplete', 'old', 'that', 'this']

for thing in os.listdir(startingDir):
    clips = []
    name = ''
    
    if thing in avoid:
        print('                              avoided {}'.format(thing))
        continue

    folder = os.path.join(startingDir, thing)

    if os.path.isdir(folder):
        for clip in os.listdir(folder):
            print (clip)
            clips.append(VideoFileClip(os.path.join(folder, clip)))
        print('\n')

        try:
            final = concatenate_videoclips(clips)
            final.write_videofile(os.path.join(folder, 'test'), audio=True, codec='libx264', threads=10)
            final.close() 
        except Exception as e:
            print (e)
            print('\n Continuing... \n\n')
            continue


  


• Replace part of a video (without replacing the audio) in ffmpeg [closed]

  13 février 2021, par Real Noob

  I have a video file that is divided into three different sections. I want to replace the middle part of this video with another clip. However, I still want to keep the audio of the original video. Can I do that in ffmpeg ?

  


  Here are my requirements :

  


  

  1. Original Video is 60 seconds long.

  


  2. The part I want to replace is from 25 to 45 seconds.

  


  3. I want to keep the original audio from 25 to 45 seconds and just replace the visual part with some other clip.

  


  4. The generated video will also be 60 seconds long. However, it will have the new video from 25 to 45 seconds.

  


  


  Thanks.

  


• MoviePy on EC2 Instance Super Slow

  27 janvier 2020, par connorvo

  No matter what size EC2 instance I use, MoviePy.write_videofile() takes forever.

  I ran it on a t2.micro, c5.large, and c4.2xlarge and they all projected to take the same amount of time ( 7 hours).

  I have a 720mb mp4 file that I am adding a 30mb mp4 file to the beginning of and then putting a text overlay on the entire video (just static text saying the company name in the bottom corner).
