The key difference is that everything renders on your own PC. Your photos, your client's property details, and your contact information never leave your machine unless you choose to share the finished video. There's no upload queue, no waiting for a server somewhere to process your tour, and no internet connection required to export. You load your photos and videos, set your preferences, click Export, and the finished HD video is saved directly to your hard drive — typically in three minutes for the average tour.
