I have tried to preview a clip with a subtitle. But I have a error that says :

AttributeError: 'CompositeAudioClip' object has no attribute 'fps'

`from moviepy.editor import *
from moviepy.video.tools.subtitles import SubtitlesClip

# Load the video clip
video_clip = VideoFileClip("H:/movie/A.Quiet place/1.mkv")
# Define a text generator function for the subtitles
def txt_gen(txt):
    return TextClip(txt, font='Times new roman - bold', fontsize=36, color='white')
# Define the subtitle start and end times and text
sub_start_time = 0.2
sub_end_time = 5
sub_text = "This is the subtitle text"
# Create a list of subtitle tuples
subs = [((sub_start_time, sub_end_time), sub_text)]
# Create a SubtitlesClip object from the subtitle tuples and text generator
subtitles = SubtitlesClip(subs, txt_gen)
# Set the subtitle position
subtitles = subtitles.set_pos(('center', 'bottom'))
# Create a composite video clip with the video and subtitles
composite_clip = CompositeVideoClip([video_clip, subtitles])
# Preview the composite clip with subtitles
composite_clip.preview(fps=composite_clip.fps)
# Close the video preview window
composite_clip.close()`

my complete error :

using video_clip.preview (in moviepy library) u can preview clip file . this works fine any operates as expected.

but when I add a subtitle to that clip I can't preview it anymore and I get the errors above.

composite_clip is [video_clip file + subtitle]

I can save composite_clip somewhere and open it with a players like potplayer. but I cant Preview it in my program.

  • with spaecial thanks to @petezurich it's edited now. any way maybe I should explain the problem better. using video_clip.preview (in moviepylibrary) u can preview clip file . this works fine any operates as expected. but when I add a subtitle to that clip I can't preview it anymore and I get the errors above. composite_clip is the video_clip file + subtitle.
