CapCut SRT Generator (PHP + JS)

===============================

An open-source, lightweight tool to convert plain text scripts into CapCut-compatible .SRT subtitle files with accurate timing and formatting.

📌 DESCRIPTION

This tool allows content creators, video editors, and storytellers to paste their script into a textbox, set timing parameters, and instantly generate subtitles for platforms like CapCut or Premiere Pro.

✅ FEATURES

• Paste your script and generate .srt files instantly
• Adjust Words Per Second (WPS), Minimum Duration, and Pause Padding
• Copy subtitles or download the .srt file
• Clean and responsive 60/40 UI layout with live preview
• Fully runs in-browser with a PHP backend (no database required)

🚀 HOW TO USE

1. Clone or download the repository to your localhost or web server.
2. Make sure you have PHP installed (PHP 7.4 or later recommended).
3. Ensure the /srt_files/ folder exists and is writable:
   • On Linux/Mac: mkdir srt_files chmod 775 srt_files
4. Open index.php in your browser via localhost (e.g. http://localhost/CapCut-SRT/index.php).
5. Paste your text, adjust timing, and click “Process” to preview subtitles.
6. Use the Copy or Download buttons to export your final .srt file.
