# MagicSRT — The Most Accurate & Cost-Effective Video Subtitle Service on Earth

## Overview
MagicSRT is a web-based AI-powered video subtitle generation and translation platform for YouTube creators and video professionals. Upload any video to automatically generate subtitles, then translate into 60 quality-verified languages — all with perfect timecode preservation. $5.50 for a 2-hour video. $1 per language for context-aware translation.

## Two Core Products

### 1. Video Subtitle Generation (BS Video Engine)
Upload any video file (up to 2GB / 2 hours) and MagicSRT's AI automatically:
1. Analyzes the video and generates precise subtitles with accurate timestamps
2. Creates chapter summaries for easy video navigation
3. Delivers a complete SRT file ready for download or translation

**Pricing**: 15-55 MP based on duration ($1.49-$5.44). 2-hour video = $5.50.
**Privacy**: Uploaded videos, analysis results, and subtitles are never stored on our servers.

### 2. SRT Subtitle Translation (SPDT™ Engine)
Upload an SRT file or use the one-click bridge from subtitle generation:
1. AI analyzes the full script for context (tone, terminology, speaker intent)
2. A context summary ensures consistent translation across the entire file
3. Subtitles are translated in batches with real-time streaming preview
4. Download the translated SRT with 100% timecode preservation

**Pricing**: 10 MP per language ($0.99). Multi-language: up to 5 simultaneously.

## How It Works — Video to Multilingual Subtitles
1. Upload video → 2. AI generates SRT + chapters → 3. One-click translate into 5 languages → 4. Download ZIP
Total cost for 2-hour video + 5 languages: $10.50. Competitors charge $50-130.
