ImageClip.set_duration() 在 moviepy 中不起作用

Question

我想从图像和音频制作视频文件。但是我无法导出视频。我收到了这个错误。 ValueError: Attribute 'duration' not set。我在图像剪辑上设置了持续时间。像这样。

    image_path = 'img/opening.png'
    audio_path = 'audio/opening.mp3'
    video_path = 'mov/opening.mp4'

    image_clip = ImageClip(image_path)
    audio_clip = AudioFileClip(audio_path)
    logging.info(f'audio_duration: {audio_clip.duration}')

    image_clip.set_duration(audio_clip.duration)
    image_clip.set_audio(audio_clip)
    logging.info(f'image_clip duration: {image_clip.duration}')
    
    image_clip.write_videofile(video_path)

这是结果。 audio_clip 有持续时间。但是image_clip不能设置持续时间。

INFO:root:audio_duration: 1.7
INFO:root:image_clip duration: None

如果你有什么想法，请帮助我！

Answer 1

.set_duration() 和 .set_audio() 需要在 image_clip 上设置。

    image_clip = image_clip.set_duration(audio_clip.duration)
    image_clip = image_clip.set_audio(audio_clip)

ImageClip.set_duration() 在 moviepy 中不起作用

ImageClip.set_duration() does not works in moviepy
