The Metadata step is to extract metadata from audio and video files such as start timecode, framerate, duration, resolution and more.
Here's how to set it up:
1. Add Metadata step to the Flow
2. Select "Read metadata" as the action
3. Setup Metadata option (Bind the source video)
4. You can save the extracted metadata to a Table by adding a "Table" step the Flow. This allows you to use the metadata later.
5. Save and enable the Flow (i.e. turn it on) and check the log for the result.
