我们从Python开源项目中，提取了以下4个代码示例，用于说明如何使用moviepy.editor.CompositeVideoClip()。
def add_text_to_movie(movie_fol, movie_name, out_movie_name, subs, fontsize=50, txt_color='red', font='Xolonium-Bold'): # Should install ImageMagick # For centos6: https://www.vultr.com/docs/install-imagemagick-on-centos-6 from moviepy import editor def annotate(clip, txt, txt_color=txt_color, fontsize=fontsize, font=font): """ Writes a text at the bottom of the clip. """ txtclip = editor.TextClip(txt, fontsize=fontsize, font=font, color=txt_color) # txtclip = txtclip.on_color((clip.w, txtclip.h + 6), color=(0, 0, 255), pos=(6, 'center')) cvc = editor.CompositeVideoClip([clip, txtclip.set_pos(('center', 'bottom'))]) return cvc.set_duration(clip.duration) video = editor.VideoFileClip(op.join(movie_fol, movie_name)) annotated_clips = [annotate(video.subclip(from_t, to_t), txt) for (from_t, to_t), txt in subs] final_clip = editor.concatenate_videoclips(annotated_clips) final_clip.write_videofile(op.join(movie_fol, out_movie_name))
