# Container vs. Codec
# Container: Das Dateiformat
**Container = Die Box**
Verpackt Video, Audio, Untertitel, Metadaten
**Was ist ein Container?**
Das Dateiformat – eine "Box", die verschiedene Streams zusammenpackt:
- Video-Stream, Audio-Stream(s), Untertitel, Metadaten
**Beispiele:** MP4, MKV, AVI, MOV
**Gängige Container:**
- **MP4** (.mp4) – Web, Streaming
- **MKV** (.mkv) – Archiv, viele Streams
- **AVI** (.avi) – Legacy (veraltet)
- **MOV** (.mov) – Apple-Ökosystem
**Codec = Kompressionsalgorithmus**
Entscheidet, WIE Daten komprimiert werden
<!--
Container = Verpackung, nicht der Inhalt
Ein MP4 sagt nichts über die Qualität aus
MKV kann beliebig viele Audio/Untertitel-Spuren haben
-->
**Video-Codecs:** H.264, H.265, VP9, AV1
**Audio-Codecs:** AAC, MP3, Opus
---
# Codec: Der Kompressionsalgorithmus
**Was ist ein Codec?** (Coder/Decoder)
Entscheidet, WIE Video/Audio komprimiert wird
**Video-Codecs:**
| Codec | Jahr | Verbreitung |
|-------|------|-------------|
| H.264/AVC | 2003 | Universell, überall |
| H.265/HEVC | 2013 | 4K, effizient, Lizenzen |
| VP9 | 2013 | YouTube, Google |
| AV1 | 2018 | Zukunft, lizenzfrei |
**Audio-Codecs:** AAC, MP3, Opus, FLAC
<!--
H.264 = De-facto-Standard seit 20 Jahren
H.265 = 50% kleinere Dateien, aber teure Lizenzen
AV1 = Open Source, Netflix/YouTube pushen es
-->
---
# Container + Codec = Video
**Das Zusammenspiel:**
```
┌─────────────────────────────┐
│ Container (z.B. MP4) │
│ ┌────────────────────────┐ │
│ │ Video-Stream (H.264) │ │
│ ├────────────────────────┤ │
│ │ Audio-Stream (AAC) │ │
│ ├────────────────────────┤ │
│ │ Untertitel (SRT) │ │
│ └────────────────────────┘ │
└─────────────────────────────┘
```
**Häufiger Irrtum:** "Das ist eine MP4-Datei"
→ Sagt nichts über den Codec aus!
<!--
Container ≠ Codec (häufiges Missverständnis!)
MP4 ist KEIN Codec, sondern Container
Schachtel-Analogie: Container = Karton, Codec = Inhalt
Ein MP4 kann H.264, H.265 oder AV1 enthalten
Prüfen mit: MediaInfo, ffprobe
