)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.
