SRTMerger

Overview

The SRTMerger script is designed to merge and manipulate subtitle files in the SRT format. It takes two SRT files and a set of commands to produce a merged output file.

Usage

The script is initialized with four parameters:

• srt1_filename: The filename of the first SRT file.
• srt2_filename: The filename of the second SRT file.
• commands_filename: The filename containing the commands to process.
• output_filename: The filename where the merged output will be saved.

Supported Commands

The script supports the following commands:

COPY

Copies subtitles from one file to the output.

Syntax:

COPY <source> <start> <end>

• <source>: The source SRT file (srt1 or srt2).
• <start>: The starting index of the subtitles to copy.
• <end>: The ending index of the subtitles to copy.

MAP

Maps text from one file to another with a time offset.

Syntax:

MAP <text_source> <text_start> <time_start> <count>

• <text_source>: The source SRT file for text (srt1 or srt2).
• <text_start>: The starting index of the text to map.
• <time_start>: The starting index of the time to map.
• <count>: The number of subtitles to map.

SYNC

Synchronizes subtitles between files.

Syntax:

SYNC <text_source> <text_index> <time_index>

• <text_source>: The source SRT file for text (srt1 or srt2).
• <text_index>: The index of the text to synchronize.
• <time_index>: The index of the time to synchronize.

PUT

Puts a specific text at a given index.

Syntax:

PUT <source> <index> <text>

• <source>: The source SRT file (srt1 or srt2).
• <index>: The index where the text should be placed.

Output

The processed commands will generate a merged SRT file saved to the specified output_filename.
