Tool Options

Merge options

Choose how the secondary file blends with the primary file: interleave, append sequentially, or overlay overlapping cues.

File selection

Pick a primary file first, then choose the secondary file to merge with it.

Select your files
Interleave strategy

Combine cues by timestamp so dialogue from both files appears in chronological order. Overlapping lines are positioned to avoid collisions.

Sequential strategy

Append the secondary file after the primary one ends. Ideal for multi-part recordings or stitched-together episodes.

Overlay strategy

Merge overlapping cues into a single entry so multi-language subtitles or speaker tags can share the same timestamp.
