Scored 55. Functional subtitle generator with multiple modes and language support. Good CLI design with clear flags. Hebrew specialization adds niche value but limits broader appeal. No error handling documented.

# Video Subtitles

Generate movie-style subtitles from video or audio files. Supports transcription, translation, and burning subtitles directly into video.

## Features

- **Hebrew**: ivrit.ai fine-tuned model (best Hebrew transcription)
- **English**: OpenAI Whisper large-v3
- **Auto-detect**: Automatically detects language and selects best model
- **Translation**: Translate Hebrew → English
- **Burn-in**: Hardcode subtitles into video (visible everywhere, including WhatsApp)
- **Movie-style**: Natural subtitle breaks (42 chars/line, 1-7s duration)

## Quick Start

```bash
# Plain transcript
./scripts/generate_srt.py video.mp4

# Generate SRT file
./scripts/generate_srt.py video.mp4 --srt

# Burn subtitles into video (always visible)
./scripts/generate_srt.py video.mp4 --srt --burn

# Translate to English + burn in
./scripts/generate_srt.py video.mp4 --srt --burn --translate en

# Force language
./scripts/generate_srt.py video.mp4 --lang he    # Hebrew

```
