Start with the videos already on your PC. Add a folder to build the library, then find a video by its thumbnail or name.
- Open Library.
- Use Manage Folders to add the folder containing your videos.
- Return to All Videos. Cards show a title, duration, format, resolution and size; HDR videos carry an HDR badge.

Casting and 10-bit HDR are CnX Pro features, with a free trial on every video. Check the app for the options available to you.
