Google Translate Channel:

Completely free and with no frequency limits, but as everyone knows, Google is inaccessible in China. Therefore, to use it, you must fill in the "Network Proxy Address." If you are using v2ray, then fill in http://127.0.0.1:10808. If you are using Clash, then fill in http://127.0.0.1:7890. The process is similar for other tools. Note that even if you have enabled a global proxy, the software may not necessarily use that proxy. 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 use the Google or FreeGoogle translation channel to add target languages. Other channels do not support adding new languages.

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 code in this text box, separating multiple codes with English commas. For example, if the Uyghur language code is ug, then enter ug here. If you also want to add Hebrew, find its code he, and add he to the text, remembering to separate multiple codes with English commas.
