Quick start

$ pip install captacity
$ captacity <video_file> <output_file>

Programmatic use

import captacity

captacity.add_captions(
    video_file="my_short.mp4",
    output_file="my_short_with_captions.mp4",
)

Custom configuration

import captacity

captacity.add_captions(
    video_file="my_short.mp4",
    output_file="my_short_with_captions.mp4",

    font = "/path/to/your/font.ttf",
    font_size = 130,
    font_color = "yellow",

    stroke_width = 3,
    stroke_color = "black",

    shadow_strength = 1.0,
    shadow_blur = 0.1,

Using Whisper locally

By default, OpenAI Whisper is used locally if the openai-whisper package is installed. Otherwise, the OpenAI Whisper API is used. If you want to force the use of the API, you can specify use_local_whisper=False in the arguments to captacity.add_captions:

import captacity

captacity.add_captions(
    video_file="my_short.mp4",
    output_file="my_short_with_captions.mp4",
    use_local_whisper=False,
)

You can install Captacity with pip install captacity[local_whisper] to install Whisper locally as well.
