LibreTranslate is a free and open-source machine translation API, self-hosted, supports offline use, and is easy to set up.
It can be deployed and used locally. Video translation software v3.00 and later versions support its use.
After filling in the API address and API key in the software's menu bar -> Translation Settings -> LibreTranslate API, test it to ensure no issues, and then you can start using it.

Fill in the API URL
You can deploy it yourself and then fill in the API URL with your locally deployed address. Alternatively, you can use the paid API address provided by LibreTranslate's official service: https://libretranslate.com/translate
If using the official address, you must provide a valid API key, which can be purchased from their official site: https://portal.libretranslate.com/
