Merge Subtitles

Combine two subtitle files into one — interleave by timestamp, stack text side by side, or append sequentially.

Merge Mode

Merge entries from both files sorted by start time. Ideal for dual-language.
For overlapping entries, show both texts in the same cue. Great for dual-language display.
Concatenate sequentially — File 2 entries come after all of File 1.

Merge modes explained

Interleave by timestamp

Entries from both files are sorted together by their start time. Use this to combine subtitles for two speakers or two audio channels into a single chronological SRT.

Stack text (dual subtitles)

When two entries overlap in time, their text lines are combined in the same cue. Perfect for showing two languages simultaneously — e.g. original language on top, translation below.

Append sequentially

All entries from File 2 are appended after all entries from File 1, with indices renumbered. Use this to combine subtitles for two separate parts of a video into one file.
