I'm tried to follow this example how to add subtitles to a movie clip:
from moviepy.video.tools.subtitles import SubtitlesClip
from moviepy.video.io.VideoFileClip import VideoFileClip
subs = [((0, 3), 'sub1'),
((3, 7), 'sub2'),
((9, 11), 'sub3'),
((11, 16), 'sub4')]
subtitles = SubtitlesClip(subs)
clip = VideoFileClip(video_fname)
video = movedit.CompositeVideoClip([clip, subtitles])
video.to_videofile(output_video_name)
But the output movie turned out without subtitles. Am I doing something wrong? btw, the subtitles.py doesn't work with python 3, this line of code
subtitles = [(map(cvsecs, tt),txt) for tt, txt in subtitles]
Is needed to be changed to
subtitles = [(list(map(cvsecs, tt),txt)) for tt, txt in subtitles]
Edit
Eventually I've created subtitles the hard way:
from moviepy import editor
import os.path as op
def annotate(clip, txt, txt_color='red', fontsize=50, font='Xolonium-Bold'):
""" Writes a text at the bottom of the clip. """
txtclip = editor.TextClip(txt, fontsize=fontsize, font=font, color=txt_color)
cvc = editor.CompositeVideoClip([clip, txtclip.set_pos(('center', 'bottom'))])
return cvc.set_duration(clip.duration)
video = editor.VideoFileClip(op.join(movie_fol, movie_name))
subs = [((0, 4), 'subs1'),
((4, 9), 'subs2'),
((9, 12), 'subs3'),
((12, 16), 'subs4')]
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))
It's not perfect, there is still room for improvement, like supporting time ranges without subtitles, but it solved my problem.
