Moviepy - TextClip的CompositeVideoClip错误

Question

我正在尝试将文本添加到由concatenate_videoclips生成的剪辑中，但不断收到错误。我尝试将文本单独添加到每个剪辑中，然后连接，但我得到了相同的错误。

下面是我的代码：

clip_list = []
for file in movie_maker_directory:
    clip = VideoFileClip('C:\dev\movie_maker\{}'.format(file))
    if clip.rotation != 0:
        clip = clip.rotate(-clip.rotation)
    clip = clip.resize(height=1080)
    clip_list.append(clip)
final_clip = concatenate_videoclips(clip_list, method="compose")
text = TextClip('Documentary Title', fontsize=5).set_position(('top', 'left'))
final_clip = CompositeVideoClip([text, clip])
final_clip.write_videofile("C:\dev\movie_maker\my_concatenation.mp4")

下面是错误消息：

Answer 1

我想你的定位颠倒了。试着这样做：

text = TextClip('Documentary Title', fontsize=5).set_position(('left', 'top'))
