🎬 Video and Audio to Text Transcription

🧠 Overview

This script is designed for the Apify platform and uses OpenAI Whisper to transcribe audio or video (e.g., from YouTube or MP4 files) into text and other formats (SRT, VTT, etc.).

📥 Input

✅ Note: Models tiny, base, and small are already downloaded in the Docker image for faster and offline-ready processing.
