How to Use the Real-Time Video Translator
Obtain a free API key from the DeepL API menu on the DeepL website (https://www.deepl.com/pro#developer), enter it in the DeepL API Key field in the settings, check the supported video platforms, select the translation language, and save.
For example, on a YouTube video like this, click the subtitle (c) button below the video to enable subtitles. The extension will translate them in real time into the selected language. Disabling the subtitle (c) button will also stop the real-time translation.
