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，我收到了这个错误。我最初只是尝试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？
data 变量包含一些其他变量的列表，视频名称、起点、终点等。
此代码旨在将一个视频放入另一个视频中。
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')
这是我的追溯：
