Semantic search
Cardboard automatically analyzes your media on import, which means you can search by what is in the content — not just file names.- Visual search
- Speech search
- Music & sound
Search by what you see in the video. Cardboard uses AI video analysis to understand the visual content of every clip.Example searches:
- “city skyline”
- “person holding a phone”
- “outdoor nature shots”
- “close-up of a face”
What gets analyzed
When you import a file, Cardboard runs several AI processes in the background:| Analysis | What it does | Used for |
|---|---|---|
| Thumbnails | Generates preview frames | Grid view, hover preview |
| Transcription | Converts speech to text with word-level timestamps | Speech search, captions |
| Video analysis | Identifies scenes, objects, and actions | Visual search, AI editing |
| Waveform | Creates an audio waveform visualization | Timeline display |
| Embeddings | Builds semantic vectors for content | Semantic search |
