What programming languages are supported for integration?

HeyGen CLI outputs structured JSON, making it compatible with any programming language that can parse JSON, such as Python, JavaScript, or Bash.

Is there a GUI available, or is it only CLI?

Currently, HeyGen CLI is primarily a command-line tool designed for automation, with no standalone GUI, but it can be used in scripts and systems without a graphical interface.

How does the translation feature work?

The translation feature uses integrated APIs or models to translate text content within videos or other media, outputting results in JSON format for easy processing.

Can I use this for real-time or live applications?

HeyGen CLI is optimized for batch processing and automation in scripts, so it may not be suitable for real-time applications without additional customization or setup.
