-# Davinci Video Converter
+# DaVinci Video Converter

-This is a simple tool that converts your `.mp4` videos into a format that DaVinci Resolve uses on Linux. The application utilizes `ffmpeg` for video conversion.
+A command-line video conversion tool optimized for DaVinci Resolve workflows.

 ## Features

- Convert `.mp4` videos to DNxHD format.
- Simple command-line interface for user input.
+- Convert videos using various codecs (H.264, H.265, ProRes)
+- Quality presets for different use cases
+- CRF-based quality control
+- Verbose output for debugging

-## Prerequisites
+## Development Environment

-Before building and running the application, ensure you have the following installed:
+### DevContainer (Podman)

- `g++` (GNU C++ Compiler)
- `make` (Build automation tool)
- `ffmpeg` (Multimedia framework for handling video, audio, and other multimedia files)
+This project includes a DevContainer configuration for use with Podman. To use it:

-## Installation
+1. Install the Dev Containers extension in VS Code
+2. Configure VS Code to use Podman:
+   - Set `remote.containers.defaultDockerCommand` to `podman` in VS Code settings
+3. Reopen the project in the container (Ctrl+Shift+P → "Dev Containers: Reopen in Container")

-### Using the Build Script
+The container includes all necessary dependencies (g++, make, ffmpeg).

-1. Clone the repository:
-   ```bash
-   git clone (https://github.com/tkmxqrdxddd/davinci-video-converter)
-   cd davinci-video-converter
-   ```
+### Nix Shell

-2. Run the build script to install dependencies and build the project:
-   ```bash
-   ./build.sh
-   ```
-
-   This script will automatically install the required dependencies based on your Linux distribution and build the project. It will also install the application to `/usr/bin`, making it accessible from anywhere.
-
-### Manual Installation
-
-If you prefer to install manually, follow these steps:
-
-1. Install the required dependencies (if not already installed):
-   - For Debian-based systems:
-     ```bash
-     sudo apt-get install -y build-essential ffmpeg
-     ```
-   - For Red Hat-based systems:
-     ```bash
-     sudo dnf install -y gcc-c++ ffmpeg make
-     ```
-   - For Arch Linux:
-     ```bash
-     sudo pacman -Syu --noconfirm base-devel ffmpeg
-     ```
-   - For openSUSE:
-     ```bash
-     sudo zypper install -y gcc-c++ ffmpeg make
-     ```
-   - For Alpine Linux:
-     ```bash
-     sudo apk add --no-cache g++ ffmpeg make
-     ```
-
-2. Build the project using `make`:
-   ```bash
-   make
-   ```
-
-   This will create an executable named `davinci-convert` in the `output` directory.
-
-3. Install the application:
-   ```bash
-   make install
-   ```
-
-## Running the Program
-
-To run the program, use the following command:
+For Nix users, enter the development shell:

 ```bash
-davinci-convert
+nix-shell
 ```

-### Usage
+This provides a development environment with g++, make, and ffmpeg.

-1. When prompted, enter the input file path of the `.mp4` video you want to convert.
-2. Enter the desired output file path (including the filename and extension) for the converted video.
-3. The program will start the conversion process. You will see messages indicating the progress.
-4. Once the conversion is complete, you will receive a success message.
+## Building

-### Cleaning Up
+### Using Make
+
+```bash
+make
+```
+
+### Using build.sh
+
+```bash
+./build.sh
+```
+
+### Clean Build

-To clean up the generated files (object files and the executable), run:
 ```bash
 make clean
 ```

-## Contributing
+## Usage

-If you would like to contribute to this project, please fork the repository and submit a pull request. Any contributions, bug reports, or feature requests are welcome!
+```bash
+./davinci-video-converter [options] <input> <output>
+```
+
+### Options
+
+| Option | Description | Default |
+|--------|-------------|---------|
+| `-c, --codec <codec>` | Video codec (h264, h265, prores) | h264 |
+| `-q, --quality <qual>` | Quality preset (fast, medium, slow) | medium |
+| `-r, --crf <value>` | CRF value 0-51 | 23 |
+| `-v, --verbose` | Enable verbose output | false |
+| `-h, --help` | Show help message | - |
+
+### Examples
+
+Convert with default settings:
+```bash
+./davinci-video-converter input.mp4 output.mp4
+```
+
+Convert with H.265 codec and slow preset:
+```bash
+./davinci-video-converter -c h265 -q slow input.mp4 output.mp4
+```
+
+Convert with custom CRF value:
+```bash
+./davinci-video-converter -r 18 input.mp4 output.mp4
+```
+
+Verbose conversion:
+```bash
+./davinci-video-converter -v input.mp4 output.mp4
+```
+
+## Testing
+
+Run the built-in tests:
+
+```bash
+make test
+```
+
+## Installation
+
+```bash
+sudo make install
+```
+
+## Uninstallation
+
+```bash
+sudo make uninstall
+```
+
