Quick Start

Beautiful Captions provides two API styles to suit your needs:

Functional API

from beautiful_captions import add_captions, transcribe, process_video

# Using an existing SRT file
subtitles_from_srt("input.mp4", "subtitles.srt", style="default")

# Transcribe and caption
transcribe("video.mp4", service="assemblyai", api_key="YOUR_KEY")
subtitles_from_srt("video.mp4", "generated.srt", style="default")

# All-in-one process
add_subtitles("input.mp4", 
    transcribe_with="assemblyai",
    api_key="YOUR_KEY",
    style="default"
)

Object-Oriented API

from beautiful_captions import Video

# Using an existing SRT file
video = Video("input.mp4")
video.subtitles_from_srt("subtitles.srt", style="default")
video.save("output.mp4")

# Transcribe and caption
video = Video("input.mp4")
video.transcribe(service="assemblyai", api_key="YOUR_KEY")
video.subtitles_from_srt(style="default", animation="bounce")
video.save("output.mp4")

Styling Options

Customize your captions with these options:

from beautiful_captions import Style

style = Style(
    font="Arial",          # Font family
    color="white",         # Text color
    outline_color="black", # Outline color
    outline_width=2,       # Outline thickness
    position="bottom",     # Vertical position
    animation="bounce"     # Animation type
)

add_captions("input.mp4", "subtitles.srt", style=style)

Transcription Services

Beautiful Captions supports multiple transcription services out of the box:

# Using AssemblyAI
video.transcribe(service="assemblyai", api_key="YOUR_ASSEMBLYAI_KEY")
