Google Translate Channel:

Completely free and with no rate limits. However, Google is inaccessible in China, so to use it, you must fill in the "Network Proxy Address". If you are using v2ray, fill in http://127.0.0.1:10808. If you are using clash, fill in http://127.0.0.1:7890. Similar settings apply to other tools. Note that even if you have enabled a global proxy, the software may not necessarily use it, so please try to fill in the network proxy address.

How to add a target language if it's missing in batch subtitle translation?

You must first use the Google or FreeGoogle translation channel to add target languages; other channels do not support this.

Then, click Menu - Tools/Options - Advanced Options. In the window that opens, find the "Google Translate Add Language Code" text box. Enter the desired target language codes in this text box, separated by English commas. For example, the Uyghur language code is ug, so enter ug here. If you also want to add Hebrew, find the language code he, and add he to the text, remembering to separate multiple codes with English commas.
