What is subtitle merging and why would I need it?

Subtitle merging combines two subtitle files into one. It's useful for creating multi-language subtitles, fixing missing dialogue, combining CD1/CD2 subtitles, or creating bilingual learning materials.

What are the different merge modes available?

We offer three merge modes: Simple merge (combines files as-is), Nearest cue mode (smart timing combination), and Glue end-to-end mode (for combining CD1/CD2 subtitles).

Can I merge subtitles in different languages?

Yes! Our subtitle merger is perfect for creating multi-language subtitles. You can combine subtitles in different languages to create bilingual subtitle files.

What subtitle formats can be merged?

Our merger supports SRT, VTT, SUB, ASS, SBV, and STL subtitle formats. You can merge files of the same format or different formats.

Is the subtitle merger free to use?

Yes, our subtitle merger is completely free with no registration required. You can merge unlimited subtitle files.

Merge Modes Explained

Simple Merge

Combines both subtitle files without changing timing. All subtitles from both files are included.

• Best for: Multi-language subtitles
• Preserves original timing
• No intelligent merging

Nearest Cue Mode

Smart merging that combines nearby subtitles within the threshold to prevent jumping.

• Best for: General merging
• Prevents subtitle jumping
• Adjustable threshold

Glue End-to-End

Designed for combining CD1/CD2 subtitles by shifting the second file's timing.

• Best for: CD1/CD2 combination
• Requires CD1 duration
• Automatic time shifting

Pro Tip: Use "Nearest Cue Mode" with a 500ms threshold for most merging scenarios. It provides the best balance between accuracy and preventing subtitle conflicts.
