+ Video Release Tooling
+=======================
+
+## Ein Tool zur verarbeitung vom Streamdump zum media.ccc.de Release
+
+### 📝 Beschreibung
+Dieses Skript hilft dabei, automatisch das richtige Intro- und Outro-File sowie die passenden Teile einer chunked Aufnahme auszuwählen (z. B. OBS mit automatischem Split alle 5 Minuten).
+
+**Features:**
+- Automatische Auswahl der relevanten Videodateien
+- Vorschau der ersten und letzten Datei in `mpv`
+- Manuelle Eingabe der Start- und Endpunkte zur Feinanpassung
+- Automatische Zusammenfügung mit Intro und Outro
+- Audio-Normalisierung für das finale Video
+
+Es wird angenommen, dass Intros und Outros als Bilder oder Video verfügbar sind.
+Außerdem wurde der Stream in Snippets recorded.
+
+### 🛠️ Voraussetzungen
+Das Skript setzt die folgenden Abhängigkeiten voraus:
+- `ffmpeg`
+- `fzf`
+- `mpv` (optional, für die Vorschau)
+
+### ⚙️ Installation
+
+Stelle sicher, dass `ffmpeg` und `fzf` installiert sind:
+```bash
+sudo apt install ffmpeg fzf   # Debian/Ubuntu
+brew install ffmpeg fzf       # macOS (Homebrew)
+yay -S ffmpeg fzf             # Arch Linux (AUR)
+```
+
+### 🛠️ Nutzung
+
+1. Bereite die Ordner mit Intos, Outros und Snippets vor
+2. Führe das Skript aus:
+  ```bash
+  ./render-chunks.sh
+  ```
+3. Wähle intro, outro und die releavanten Videodateien aus.
+3. Nutze `mpv`, um die Start- und Endpunkte zu bestimmen.
+4. Gib diese Werte im Skript an.
+5. Warte, bis das finale Video gerendert wurde.
