How Subtitle Merger Works

Interleave Strategy

Combines subtitles from both files in chronological order based on timestamps. When subtitles overlap, they are positioned to avoid conflicts.

Sequential Strategy

Appends the secondary file after the primary file ends. Useful for combining subtitles for different parts of a video or multiple episodes.

Overlay Strategy

Combines overlapping subtitles into single entries when they occur at the same time. Perfect for merging different language tracks or speaker identification.
