我有一个与这条线类似的问题，但区别在于我根本没有试图更改文件夹，它仍然应该能够读取文件。我不明白为什么会有问题？

for x in newfiles:
    x = x + ".mp4"
    xstr = x
    xstr2 = xstr.replace(".mp4", "")
    x = VideoFileClip(x)
    x = x.resize(width=720)
    durationsecs = x.duration
    fullclip = CompositeVideoClip([bgnosnd.set_position((0,0)).set_end(durationsecs), x.set_position((0,20))], size=(720, 1080))
    textclip = TextClip(f"Part {xstr2}", font="fjalla-one.ttf",fontsize=125, color="white", stroke_color="black", stroke_width=5)
    textclip = textclip.set_pos('center').set_duration(durationsecs) 
    fullclip = CompositeVideoClip([fullclip, textclip])
    fullclip = fullclip.volumex(per)
    fullclip = vfx.make_loopable(fullclip, 0.5)
    fullclip.write_videofile(f"final{xstr}")

代码正确地处理两个输入视频，并在抛出错误之前发出一个工作输出文件，但我仍然不确定如何修复该错误。它似乎以前在测试文件上起作用，但从那以后，我做了一些更改。需要注意的一点是，我的当前文件是用以下代码从mkv文件转换为mp4文件的：

  convert = VideoFileClip(filename)
  convert.write_videofile(f"converted_{filename2}.mp4", codec="libx264",audio_codec="aac")

我试图用多个用相同代码转换的文件来实现这一点，但似乎没有一个文件能工作。另外要注意的是，我的python和pip只与" pip3“和"python3”一起工作，而不是正常情况下--我无法通过pip3安装imagemagick，但是我让它处理brew 完全错误：。

OSError: MoviePy error: failed to read the first frame of video file 1.mp4. That might mean that the file is corrupted. That may also mean that you are using a deprecated version of FFMPEG. On Ubuntu/Debian for instance the version in the repos is deprecated. Please update to a recent version from the website.

我试着复制并得到了和你一样的错误。

这是一个已知的问题，在最新发布 of MoviePy中得到了解决。

在我安装了最新的版本之后，对我来说，问题就消失了：

pip uninstall moviepy
pip install moviepy==2.0.0.dev2
