Njord Player is a document-based application. When launching the app, you will start with an empty document. It is recommended to add boat data and media assets from a single race or racing day to a document only, and create additional documents for other racing days.
To add content to a document, follow these guides:
Once data has been added, configure media playback in the main window and additional windows, and seek on the timeline to play back the race at any point in time.
Don't forget to save the document – this will allow to pick up after reopening the Njord Player app.
