# Media-to-media transformations

> Turn media content into books, podcasts, and other usable formats.

Arka supports content-aware transformations, not just file-extension changes:

```bash theme={null}
arka media_transform podcast.mp3 --to book --output podcast-book.md
arka media_transform notes.md --to podcast --output notes.mp3
arka media_transform "https://youtube.com/playlist?list=PLAYLIST_ID" --to book --output playlist-book.md
arka media_transform presentation.pptx --to book --output presentation-book.md
arka media_transform slide.png --to book --output slide-book.md
```

Audio/video sources use captions or transcription, YouTube playlists combine
the available video transcripts into chapters, and text/book sources can be
spoken with Arka's TTS backend. Install FFmpeg/Whisper for local media
transcription and run `arka tts-setup` for podcast output when Edge TTS is not
already available. Missing captions or dependencies produce an explicit error;
Arka never silently creates an empty book or audio file.
