Bilibili subtitle json2srt

This tool converts Bilibili JSON subtitle files into the widely supported SRT format. Bilibili, a popular video-sharing platform, uses JSON-based subtitles for its videos, but many video players and editing tools require SRT files for compatibility.

Key Features

• Simple conversion from Bilibili's JSON format to standard SRT
• Preserves all timing information and text content
• Generates properly formatted SRT files with sequential numbering
• Maintains original subtitle positioning when possible

How It Works

The conversion process analyzes the Bilibili JSON structure which contains subtitle entries with:

• Start and end timestamps (in seconds)
• Subtitle text content
• Positioning information (for on-screen placement)

The tool transforms this data into SRT format which uses:

• Sequential numbering for each subtitle
• HH:MM:SS,mmm timestamp format
• Simple text content without styling

Usage Scenarios

This conversion is particularly useful when:

• Downloading Bilibili videos with subtitles for offline use
• Editing subtitles in video editing software that only accepts SRT
• Sharing videos with others who need standard subtitle formats
• Archiving video content with more universally readable subtitles

While some formatting information from the original JSON may be lost in conversion, the essential timing and text content remain intact, making the subtitles fully functional in most video players and editing applications.
