Subtitle Renamer

A utility to rename subtitle files to match video files based on episode numbers.

Overview

Subtitle Renamer automatically detects video files and their corresponding subtitle files based on episode numbers or similar patterns, and renames the subtitle files to match the video files while preserving their extensions.

This is particularly useful for TV shows, anime, or any video content with episodes where you want the subtitle filenames to match the video filenames.

Installation

Install from PyPI:

pip install subtitle-renamer

Usage

Command Line

subtitle-renamer [options]

Options

• -v, --video-dir: Directory containing video files (defaults to current directory)
• -s, --subtitle-dir: Directory containing subtitle files (defaults to video directory)
• -r, --recursive: Search recursively in directories
• -d, --dry-run: Show what would be done without actually renaming files
• --remove-originals: Remove original subtitle files after renaming
• --keep-existing: Skip renaming if target file already exists
• --verbose: Show detailed logs
• --video-pattern: Custom regex pattern to extract episode numbers from video files (can be specified multiple times)
• --subtitle-pattern: Custom regex pattern to extract episode numbers from subtitle files (can be specified multiple times)

Examples

Basic usage (current directory):

subtitle-renamer

Specify video and subtitle directories:

subtitle-renamer --video-dir /path/to/videos --subtitle-dir /path/to/subtitles

Preview changes without renaming:

subtitle-renamer --dry-run

Recursive search through subdirectories:

subtitle-renamer --recursive

Python API

You can also use Subtitle Renamer as a library in your Python code:

from subtitle_renamer import SubtitleRenamer

renamer = SubtitleRenamer(
    video_dir="/path/to/videos",
    subtitle_dir="/path/to/subtitles",
    dry_run=True,
    recursive=True
)

renamed_count, total_count = renamer.run()
print(f"Renamed {renamed_count} of {total_count} subtitle files")

How It Works

1. The tool scans for video files and subtitle files in the specified directories
2. It extracts episode numbers using regex patterns
3. It matches video and subtitle files with the same episode number
4. It renames the subtitle files to match the video files, keeping their original extension

Supported Formats

• Video: .mkv, .mp4, .avi, .mov, .flv, .wmv, .m4v, .webm
• Subtitles: .srt, .ass, .ssa, .vtt, .sub
