SSA’s primary impact came through \k and \K tags, which enabled syllable-by-syllable highlighting. For example: Dialogue: 0,0:01:00.00,0:01:05.00,Default,,0000,0000,0000,,\K20We \K15are \K30the \K25world This command creates a progressive fill effect synchronized with audio—impossible in SRT without pre-rendering. Furthermore, the Drawing tag ( \p1m 0 0 l 100 0 100 50
