Set Audio for ImageClip using MoviePy

Question

I'm trying to turn a static png + audio into a video clip which I can then concatenate along with other video clips.

intro = ImageClip(r'D:\skrooby\Vanity\timestamp.png', duration=3)
intro.set_audio(r'D:\skrooby\introsong.mp3')
outro = ImageClip(r'D:\skrooby\Vanity\continue.png', duration=20)
outro.set_audio(r'D:\skrooby\outrosong.mp3')

While this did not raise any errors, the produced clip does not have any sound over the intro and outro sections. How can I play the audio (audio files have 3 and 20s durations correspondingly) over my images?

Answer 1

set_audio returns a copy of the clip. Do intro = intro.set_audio(...) instead.

The name is definitely confusing so in v2.0 it is being changed to with_audio : github.com/Zulko/moviepy/pull/1170
