Python 为什么在moviepy中尝试将音频文件添加到视频时出错？

我想使用python moviePy库将音频文件添加到视频文件中。 但不幸的是，我得到了这个错误。最初我只是想获取原始视频文件的持续时间，然后更改音频的大小，但这对我没有帮助。 如何解决这个问题

数据

变量包含一些其他变量的列表，如视频名称、起点、终点等。 此代码旨在将一个视频放在另一个视频中

这是我的代码：

def video_cut(data, movie1):
    folder,movie2, lista,  end, start  = data
    movie2 = f'../{movie2}'

    clip1 = VideoFileClip(movie1)
    durata = clip1.duration - end
    clip1 = clip1.subclip(0, durata)
    
    audio = f'../Rus_sound/{movie1}'[:-3] + 'mp3'
    clip1 = clip1.set_audio(AudioFileClip(audio).subclip(0, durata))
    
    w = clip1.w
    h = clip1.h
    fps = clip1.fps

    clip2 = VideoFileClip(movie2).resize(height=h, width=w).set_fps(fps)
    
    
    
    lista = [start] + [i*durata for i in lista ] + [durata]
    
    stocked = []
    for i in range(1, len(lista)):
        o = i-1
        clip = clip1.subclip(lista[o], lista[i])
        stocked.append(clip)
        if i != len(lista)-1:
            stocked.append(clip2)
    clip = concatenate_videoclips(stocked, method='compose')

    if os.path.isdir('Nova') == False: #If directory "Nova" is exist -> continue, if not - create
        os.mkdir('Nova')
    #clip.write_videofile(f'Nova/{movie1}') # Saving file in 'Nova' directory, with initially name
    clip.write_videofile(f'Nova/{movie1}'[:-3]+'mp4')

video_cut(data, '01.mkv')

这是我的回溯：
