I'd like to make video file from image and audio. However I can't export video. I got this error. ValueError: Attribute 'duration' not set. I set duration on image clip. like this.
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)
This is the result. audio_clip has duration. However image_clip can not set duration.
INFO:root:audio_duration: 1.7
INFO:root:image_clip duration: None
