def overlay_image_on_video(image_directory, video_directory, audio_directory, output_directory, image_width=1000, video_width=1080, duration=7):
    if not os.path.isdir(image_directory):
        print(f"The image directory {image_directory} does not exist.")
        return

        return
    if not os.path.isdir(audio_directory):
        print(f"The audio directory {audio_directory} does not exist.")
        return
    if not os.path.exists(output_directory):
        os.makedirs(output_directory)

    # List all video files
    video_files = [os.path.join(video_directory, f) for f in os.listdir(video_directory) if f.lower().endswith(('mp4'))]
    if not video_files:
        print(f"No videos found in {video_directory}.")
        return

    # List all image files
    image_files = [os.path.join(image_directory, f) for f in os.listdir(image_directory) if f.lower().endswith(('png', 'jpg', 'jpeg', 'bmp', 'gif'))]
    if not image_files:
        print(f"No images found in {image_directory}.")
        return

    # List all audio files
    audio_files = [os.path.join(audio_directory, f) for f in os.listdir(audio_directory) if f.lower().endswith(('mp3', 'm4a', 'wav', 'ogg'))]
    if not audio_files:
        print(f"No audio files found in {audio_directory}.")
        return

    # Randomly select one image, one video, and one audio
    image_path = random.choice(image_files)
    video_path = random.choice(video_files)
    audio_path = random.choice(audio_files)

    # Load the video and audio clips
    video_clip = VideoFileClip(video_path).subclip(0, duration)
    audio_clip = AudioFileClip(audio_path).subclip(0, duration)
    img = ImageClip(image_path)

    # Resize the image
    img = img.resize(width=image_width)

    # Calculate position to center the image vertically and with 40px padding on the sides
    x_pos = (video_width - image_width) // 2
    y_pos = (video_clip.h - img.h) // 2

    # Set the image position, duration, and apply fade-in effect
    img = img.set_position((x_pos, y_pos)).set_duration(video_clip.duration)
    img = img.fadein(0.5)

    # Overlay the image on the video
    final_clip = CompositeVideoClip([video_clip, img])
    final_clip = final_clip.set_audio(audio_clip)

    # Save the final video
    output_path = os.path.join(output_directory, os.path.basename(image_path).replace(".", "_") + ".mp4")
    final_clip.write_videofile(output_path, codec="libx264", audio_codec="aac", fps=video_clip.fps)

    print(f"Overlayed {os.path.basename(image_path)} on {os.path.basename(video_path)} with audio from {os.path.basename(audio_path)} and saved to {output_path}")

# Specify the directories
image_directory = 'scraped'
video_directory = 'vidyas'
audio_directory = 'audya'
output_directory = 'silo'

# Call the function to overlay a random image on a random video with random audio
overlay_image_on_video(image_directory, video_directory, audio_directory, output_directory)```

this is the code's script. rn, i'm facing issue with the fadein part

```py
# Set the image position, duration, and apply fade-in effect
    img = img.set_position((x_pos, y_pos)).set_duration(video_clip.duration)
    img = img.fadein(0.5)```

the problem is that fadein appears from black. But I don't see a way to make it appear from transparency instead.

Like, I can't find a way to edit the alpha channel

whatever attempt i've made thus far has been pointless

media attached is how rendered videos look like. there is a black box at the start which is annoying.
