Subtitle Packaging and Compatibility

Subtitles improve accessibility, but packaging them correctly avoids playback issues. This guide explains how to merge subtitles reliably.

Supported subtitle types

• SRT: Most widely supported
• VTT: Best for web playback
• ASS/SSA: Rich styling, less compatible

Recommended output containers

• MP4: Good for basic subtitles, most players
• MKV: Best for styled subtitles and multiple tracks

Tips for successful subtitle merges

• Match subtitle timing with the source video.
• Use UTF-8 encoding for non-English text.
• If playback fails, try MKV output.

Quick troubleshooting

• No subtitles shown: Confirm the player supports your subtitle type.
• Garbled characters: Re-save the subtitle file as UTF-8.
• Timing off: Adjust offset and re-merge.
