Google Translation Channel:

Completely free and unlimited in frequency, but as is well known, Google is inaccessible in China, so to use it, you must fill in the "Network Proxy Address." If you are using v2ray, enter http://127.0.0.1:10808; if using Clash, enter http://127.0.0.1:7890. Other tools are similar. Note that even if you have enabled global proxy, the software may not necessarily use that proxy, so please make sure to fill in the network proxy address.

How to Add a New Target Language for Batch Subtitle Translation?

First, you must use the Google or FreeGoogle translation channel to add a new target language; other channels do not support this feature.

Then, go to Menu → Tools/Options → Advanced Options. In the opened window, find the "Google Translation New Language Code" text box. Enter the desired target language codes in this box, separating multiple codes with English commas. For example, the language code for Uyghur is ug, so enter ug here. If you also want to add Hebrew, find its language code he and add he in the text box. Remember to separate multiple codes with English commas.

Where can you find the language codes? Visit the following address:
