srtmerger 0.1.0

SrtMerger is a tool to merge two or more subtitle (.srt) files together.

SrtMerger

A command-line tool to merge multiple SRT subtitle files with customizable colors, positions, and encodings.

Subtitle merger is a tool for merging two or more subtitles for videos. SRT Merger allows you to merge subtitle files, no matter what language are the subtitles encoded in. The result of this merge will be a new subtitle file which will display subtitles from each merged file.

Features

• Merge multiple SRT subtitle files into one
• Customize subtitle colors for each input file
• Set subtitle position (top/bottom) individually
• Support for different file encodings
• Set global defaults for all files
• Simple and intuitive command-line interface

Installation

pip install srtmerger

Usage

Python

Running in your Python script:

 from srtmerger import Merger


 m = Merger(output_path="new.srt")
 m.add('fa.srt', color="yellow", encoding="windows-1256")
 m.add('en.srt')
 m.merge()

Bash

The basic syntax is:

srtmerger [global options] file1.srt[:options] file2.srt[:options] ...

Each subtitle file can have its own configuration using colon-separated options:

• e=VALUE, encoding=VALUE: Set the file encoding (e.g., utf-8, utf-16)
• c=VALUE, color=VALUE: Set the subtitle color
• top: Position the subtitles at the top of the screen

Global Options

• -o, --output: Set path for the output file
• -e, --output-encoding: Set encoding for the output file
• -E, --default-encoding: Set default encoding for all files
• -C, --default-color: Set default color for all files
• -T, --default-top: Set default top position for all files

Examples

1. Basic merge of two subtitle files:

srtmerger sub1.srt sub2.srt -o output.srt

2. Set specific options for each file:

srtmerger sub1.srt:encoding=utf-8:color=yellow:top sub2.srt:color=blue --output output.srt

The above command is equivalent to:

srtmerger sub1.srt:e=utf-8:c=yellow:top sub2.srt:c=blue -o output.srt

3. Use global defaults with some overrides:

srtmerger -o output.srt -E utf-8 -C white sub1.srt sub2.srt:color=blue
