AttributeError:“str”对象没有属性“duration”

Question

我正在尝试使用moviepy编辑我的视频。当我想切一部分的时候，我得到了一个错误： AttributeError: 'str' object has no attribute 'duration' 为什么?

from moviepy.editor import *
clip0 = VideoFileClip('08.mkv')
clip0 = clip0.set_audio(f'../Rus_sound/08.mkv'[:-3] + 'mp3')
end = 0
start = 0
lista = [0.4,0.6]
movie1 = '08.mkv'
movie2 = '../Bubble_Background_Video3.mp4'
clip0 = VideoFileClip(movie1)
audio = f'../Rus_sound/{movie1}'[:-3] + 'mp3'
clip1 = clip0.set_audio(audio)
    
w = clip1.w
h = clip1.h
fps = clip1.fps
clip2 = VideoFileClip(movie2).resize(height=h, width=w).set_fps(fps)
durata = clip1.duration - end
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')

这是我的错误回溯：

这里的问题是set_audio函数不接受字符串，如果您阅读文档，这一点就很清楚了。它接受一个AudioFileClip对象moviepy足够聪明，不会在那一点上做实际工作；它只记得你想要什么样的音频。稍后，当您尝试使用该剪辑时，它会尝试查找音频文件的持续时间，并在需要对象的位置找到字符串

clip1 = clip0.set_audio(AudioFileClip(audio))
