You can deliver content to your clients in two layouts: "Single Video" and "Multi-Video Album".
You can start with a "Single Video" layout, deliver a single video to your clients and when you're ready to add more media, change it to "Multi-Video Album" layout, upload more videos and deliver it again.
You can set the privacy to public or private, and also choose to enable or disable downloads.
