# 🎞️ MKV Re-Merge & CRC32 Renamer
A simple tool to help you:
- 🧩 **Re-merge MKV files** using `mkvmerge` with selected audio, subtitle, and attachments
- 🏷️ **Rename files with their CRC32 hash** for easier verification and organization
---
## 📁 Folder Structure
```
ROOT/
├── input/ # Where you place your files
├── output/ # Final output files after renaming
├── logs/ # Logs for mkvmerge commands
├── toolnix.py # Re-merge and rename
├── rename.py # Rename only
```
---
## 🚀 How to Use
### 1. 🔧 Rename File with CRC32
- Place your file(s) inside the `input/` folder.
- Run:
```sh
python rename.py
```
- The script will:
- Calculate the file's CRC32 checksum
- Rename it to include the CRC (e.g., `video.mkv` → `video [1A2B3C4D].mkv`)
- Move it to the `output/` folder
---
### 2. 🎬 Re-Merge File, Then Rename with CRC32
- Place your `.mkv` file inside the `input/` folder.
- Run:
```sh
python toolnix.py
```
You will be prompted to:
1. **Select audio tracks** (enter numbers comma-separated, e.g., `2` or `1,3`)
2. **Select subtitle tracks** (same format)
3. **Enter the video title** (shown in MediaInfo or in your video player when you play the video)
4. **Enter the output filename** (press Enter to use the title)
The script will:
- Use `mkvmerge` to combine selected tracks
- Set the **first selected audio and subtitle as default**
- Save the output to `input/`
- Automatically rename it with CRC32 and move to `output/`
Logs for each `mkvmerge` run are saved in `logs/mkvmerge-YYYY-MM-DD.log`.
