from subliminal import download_subtitles, scan_video

# Specify the path to your video file
video_path = "path/to/your/video.mkv"

# Scan the video file to identify its details

# Download the subtitles for the video file
download_subtitles(video_files)

Customizing Subliminal

  • Language: You can specify the desired language for subtitles using the languages parameter. For example:
download_subtitles(video_files, languages=["en"])
  • Format: You can choose the subtitle format using the preferred_extensions parameter. For example:
download_subtitles(video_files, preferred_extensions=["srt"])
  • Download Location: You can specify the download location using the savepath parameter. For example:

Advanced Subliminal Usage

Subliminal provides advanced features for more complex scenarios:

  • Multiple Video Files: You can download subtitles for multiple video files simultaneously by passing a list of video paths to the scan_video function.
  • Subtitle Search Filters: You can apply filters to narrow down the search results based on specific criteria such as release date, subtitle language, and rating.
  • Custom Subtitle Sources: You can add custom subtitle sources to Subliminal to expand its capabilities beyond the default sources.

Subliminal and Movie Databases

Subliminal can also interact with movie databases like The Movie Database (TMDb) to automatically identify and download subtitles for your movies.

from subliminal import download_subtitles, scan_video, search_movie

# Search for a movie in TMDb
movie = search_movie("The Shawshank Redemption")

# Get the movie details
movie_details = movie[0]

# Scan the video file
video_files = scan_video("path/to/your/video.mkv")

# Link the video file to the movie details
video_files[0].movie = movie_details

# Download the subtitles
download_subtitles(video_files)

Subliminal and TV Shows

Subliminal can also handle TV shows. You can search for a TV show in TMDb and link it to the video file.

from subliminal import download_subtitles, scan_video, search_series

# Search for a TV series in TMDb
series = search_series("The Simpsons")

# Get the series details
series_details = series[0]

# Scan the video file
video_files = scan_video("path/to/your/video.mkv")

# Link the video file to the series details
video_files[0].series = series_details

# Download the subtitles
download_subtitles(video_files)

Subliminal in Action: A Case Study

Imagine you're watching a newly released movie, "The Great Escape," and you're eager to follow the dialogue in a foreign language. You've downloaded the movie file, but it doesn't come with subtitles. This is where Subliminal shines.

First, you use Subliminal to scan the movie file. Subliminal identifies the file as "The Great Escape" and determines its release date.

Next, Subliminal searches online subtitle sources like OpenSubtitles.org and Subscene.com for subtitles that match the movie's name, release date, and the desired language.

Within seconds, Subliminal finds a suitable subtitle file and downloads it directly to your computer. Now, you can enjoy watching "The Great Escape" with subtitles, without the hassle of manually searching for them.

Troubleshooting Subliminal

While Subliminal is generally reliable, you may encounter occasional issues. Here are some common problems and solutions:

  • No Subtitles Found: If Subliminal fails to find subtitles, it might be due to a mismatched file name or lack of available subtitles for your specific video. Try double-checking the file name and searching for subtitles manually on online sources.
  • Slow Download Speeds: If the download speed is slow, it could be due to network congestion or server issues. Try downloading the subtitles at a different time or using a different network connection.
  • Subtitle Errors: If the downloaded subtitles are not working properly, it could be due to incorrect file format or synchronization issues. You can try converting the subtitle format or adjusting the subtitle synchronization settings in your video player.

Alternatives to Subliminal

While Subliminal is a popular choice, other Python libraries offer similar functionality:

  • OpenSubtitles.py: A library that directly interacts with OpenSubtitles.org, allowing you to download subtitles directly.
  • SubtitleSearcher: A comprehensive library that supports multiple subtitle sources and provides advanced search filters.

Beyond Subliminal: Integrating with Media Players

Subliminal can be integrated with media players for a seamless subtitle experience. Some media players like VLC Media Player and Plex support custom subtitle scripts. You can create a custom script that uses Subliminal to automatically download and apply subtitles when you play a movie or TV show.

The Future of Subliminal

Subliminal continues to evolve with new features and improvements. The developers are actively working on enhancing its accuracy, speed, and support for additional subtitle sources. As more media is consumed online, Subliminal is expected to play an increasingly important role in providing subtitles for a wide range of content.
