Video Subtitle Generator with Whisper and FFmpeg

This project is a video subtitle generator built using Streamlit, Whisper, and FFmpeg. It extracts audio from a video, transcribes the audio using Whisper, generates subtitles in .srt format, and adds them back to the original video. It supports both soft and hard subtitles.

Features

• Audio Extraction: Extracts audio from video files (supports .mp4 format).
• Transcription: Uses the Whisper model to transcribe the extracted audio into text.
• Subtitle Generation: Creates .srt subtitle files with timestamps for the transcribed text.
• Subtitle Embedding: Adds the generated subtitles to the video either as soft subtitles (text tracks) or hard subtitles (burned into the video).
• Streamlit Interface: Easy-to-use web interface for uploading videos and downloading the processed video with subtitles.
