translate_file_CN2VI.py

This script is designed to translate Chinese movie subtitles to Vietnamese using a local language model.

Key Features:

• Uses a local API endpoint (http://localhost:11434) for translation
• Translates SRT files to VTT format
• Preserves context by considering previous and next lines
• Maintains subtitle timing and structure

Usage:

1. Ensure the local language model API is running
2. Place SRT files in the script's directory
3. Run the script: python translate_file_CN2VI.py

The script will process all SRT files in the current directory and its subdirectories, creating corresponding VTT files with Vietnamese translations.

poster_maker_root.py

This script generates poster images for movies by extracting frames from video files.

Key Features:

• Captures frames from video files at specified intervals
• Detects faces in the captured frames
• Selects the best frame based on face detection
• Saves the selected frame as a poster image

Usage:

1. Place video files (MP4 format) in the script's directory
2. Run the script: python poster_maker_root.py

The script will process all MP4 files in the current directory and its subdirectories, creating a '0.jpg' poster image for each video.

fasttranslate_root_60s_srt_files_to_vtt.py

This script uses Google Cloud Translation API to translate SRT files to English and Vietnamese, converting them to VTT format in the process.

Key Features:

• Translates SRT files to both English and Vietnamese
• Converts SRT format to VTT format
• Uses multithreading for faster processing
• Implements a 60-second timeout for each file

Usage:

1. Set up Google Cloud credentials (GOOGLE_APPLICATION_CREDENTIALS)
2. Place SRT files alongside MP4 files in the script's directory
3. Run the script: python fasttranslate_root_60s_srt_files_to_vtt.py

The script will process all SRT files associated with MP4 files, creating '_en.vtt' and '_vn.vtt' files for each.

translate_srt_files.py

This script is similar to the previous one but focuses on translating SRT files without converting to VTT format.

Key Features:

• Translates SRT files to both English and Vietnamese
• Maintains SRT format
• Uses Google Cloud Translation API

Usage:

1. Set up Google Cloud credentials (GOOGLE_APPLICATION_CREDENTIALS)
2. Update the folder_path variable in the script to point to your SRT files
3. Run the script: python translate_srt_files.py

The script will process all SRT files in the specified folder, creating '_en.srt' and '_vn.srt' files for each.

Setup and Dependencies

To use these scripts, you'll need to install the following Python packages:

pip install opencv-python numpy requests google-cloud-translate tqdm

For the Google Cloud Translation API scripts, you'll need to set up a Google Cloud project and obtain credentials. Set the GOOGLE_APPLICATION_CREDENTIALS environment variable to point to your credentials file.

Note

These scripts are designed to work together in a pipeline for processing movie subtitles. Ensure that you have the necessary permissions and licenses for the content you're translating and processing.
