“ASS subtitles contain numerous codes for position, color, and Karaoke effects (e.g., {\pos(100,200)}); conventional translation tools may damage these.”

Root Cause Analysis

Separation of code and text

Shangyi AI can recognize both Style definitions and Dialogue lines within ASS scripts. When processing Dialogue lines, it uses regular expressions to strictly protect all special effect tags inside curly brackets {}, translating only the plain text portions.

Multiline text matching

For subtitles that use \N for forced line breaks, the AI first analyzes the full sentence for meaning, then reinserts line breaks at appropriate positions in the translation to ensure optimal screen fit.

Final Solution Summary

Dramatically boosts fansub teams’ timing and translation efficiency without compromising carefully designed subtitle effects.
