First of all, you need to ensure that your computer has installed the Srtedit 2012 tool, download installation no longer repeat.
Using Srtedit 2012 to open your ass subtitle file, you can see that the document has two languages in Chinese and English.
All rows in the selected file.
Perform "language"-"bilingual subtitle Processing"-"Empty the selected Chinese lines" (only keep the foreign language);
Perform "language"-"bilingual subtitle Processing"-"empty selected lines of foreign language" (Chinese only)
Get the new ass file and save it for a second. The naming method can be a distinction based on personal preferences, or you can also directly overwrite the previous subtitle file.
When you play the video, use the player to manually load the new caption file (which is, of course, the new file you just generated).
7done! Perfect to remove Chinese, very good retention of the English part.
The size and presentation of the subtitle font can be adjusted in the player as needed.
