In the past, video depositions have been delivered on video tape and, more recently, on DVD.  Since the start of the pandemic, the standard delivery quickly morphed into video files sent electronically, typically in MP4 file format. MP4 is a universal video format and user friendly.  Typically, a link is sent to download the files from a cloud service. It is strongly recommended to back up the files immediately after you download them to ensure they are safely kept. Video files can also be delivered on a USB stick.
