LibreTranslate is a free and open-source machine translation API, self-hosted, offline-capable, and easy to set up.

Available for local deployment, supported by video translation software v3.00 and later.

After filling in the API address and API key in the software's Menu Bar -- Translation Settings -- LibreTranslate API, and testing without issues, you can use it.

Filling in the API URL

You can deploy it yourself and then fill in the API URL with your own locally deployed address, or you can use the paid API address provided by LibreTranslate: https://libretranslate.com/translate

If using the official address, you must fill in a valid API key, which can be purchased from their official website: https://portal.libretranslate.com/

Windows Integration Package

> Baidu Netdisk address for the integration package: https://pan.baidu.com/s/1UN7WL69DA59iKHHtT6h1GQ?pwd=a5ce > Download the integration package update patch (changes the model address to the integration package directory instead of the model C drive home directory): https://pan.baidu.com/s/1yLWpJM8qXJO8sWVnZ_ew-A?pwd=g59m

After downloading and extracting, double-click start.bat. The first startup will download 92 models, which will take a long time. If you have a VPN, please set up the system proxy to prevent download failure.

After downloading and overwriting the patch package, the model address will be changed to the models folder in the integration package directory. You need to re-download the models or copy the .local folder to models as described in the patch package instructions.
