# RetroBatch — Video Codec Converter
A modern, blazing-fast batch video converter built with **Tauri v2**, **React**, and **Rust**. Specifically designed to solve the codec compatibility issues that plague editors working in **DaVinci Resolve Free** (5K+ H.264 footage, 10-bit imports, "Media Offline" errors), and to provide a beautiful drop-in tool for transcoding into professional editing codecs like **DNxHR** and **ProRes**.
---
## Why This Was Built
Anyone using the free version of **DaVinci Resolve** has been there: you import a beautiful 5K clip from your camera and Resolve refuses to import it with a "Media Offline" error. This is an artificial limitation Blackmagic places on the free version: it cannot decode H.264/H.265 footage above 4K resolution, nor any 10-bit footage.
RetroBatch was made to bypass these limitations with a single click. Drop your footage in, pick the right preset, and get back to editing.
## Features
### Core Conversion
- **Smart Queue System**: Add unlimited files, monitor progress in real-time with accurate per-file and total ETAs, and process them automatically.
- **Frame-Accurate Progress Tracking**: Real-time progress, conversion speed (e.g. 1.4x), and time-remaining estimates for each file in the queue.
- **Editor-Friendly Presets**:
- H.264 8-bit 4K Downscale (Fix 5K Resolve Free Error)
- H.264 8-bit Standard
- DNxHR HQX / SQ / LB
- ProRes 422 HQ / Proxy
- H.265 / HEVC
### Advanced Options
- **Video Trimming**: Specify Start/End times to extract clips
- **Audio Extraction**: Pull MP3 audio directly from video
- **Hardware Acceleration**: Auto-detect or manually choose NVENC / AMF / VideoToolbox
### Unique Professional Features
- **Watch Folder (Hot Folder)**: Set a folder to monitor; any video dropped in is automatically added to the queue and converted.
- **LUT Application**: Bake `.cube` color grading LUTs directly into the conversion.
- **NLE Proxy Structure Generation**: Automatically organize output into DaVinci Resolve or Premiere Pro proxy folder structures for instant linking.
- **Smart Auto-Renaming**: Use variables like `{filename}` to dynamically name your output files.
### User Experience
- **Modern Glass-Morphism UI**: Indigo & purple gradient design with smooth Framer Motion animations.
- **Frameless Custom Window**: Native title bar replaced with elegant custom controls (works on Windows, macOS, Linux).
- **Auto-Dependency Manager**: First-launch splash screen downloads and configures FFmpeg automatically. No manual install required.
## Installation
### Option 1: Download the Pre-Built Installer (Recommended)
1. Head to the [Releases](https://github.com/XonistReal/batch-video-codec-converter/releases) page.
2. Download the latest installer for your OS:
- **Windows**: `retro-converter_x.x.x_x64-setup.exe`
- **macOS**: `.dmg` (coming soon)
- **Linux**: `.AppImage` (coming soon)
3. Run the installer. On first launch, the app will automatically download FFmpeg into its app-data folder.
### Option 2: Build from Source
**Prerequisites:**
- [Node.js](https://nodejs.org) 18+
- [Rust](https://www.rust-lang.org/tools/install) (latest stable)
- [Tauri Prerequisites](https://tauri.app/start/prerequisites/) for your OS (WebView2 on Windows, Xcode on macOS, etc.)
**Steps:**
```bash
# Clone the repository
git clone https://github.com/XonistReal/batch-video-codec-converter.git
cd batch-video-codec-converter/tauri-v2-app
# Install frontend dependencies
npm install
# Run in dev mode
npm run tauri dev
# Build production release
npm run tauri build
```
Built executables will appear in `tauri-v2-app/src-tauri/target/release/`.
