HDV ( high-definition video) records to miniDV tapes according to one or both of two HD standards: 720p (1,280 by 720 progressive) or 1080i (1,440 by 1,080 interlaced). In addition to how you store footage, you'll want to think about how your video camera records it, right? Consumers depend on two main high-definition video formats: HDV, which was introduced in 2004, and AVCHD, which came out in mid-2006 and is still evolving. This functionality is typically called dual flash memory. That's helpful in case you lose that little memory card and there's a family event that has to be recorded for posterity. Some digital video cameras also allow you to choose between one of two storage formats: You can record either to the camera's internal flash drive or to a removable memory card. Recording directly to a DVD is appealing to many people because it's fast and easy you're simply recording your footage directly to its final, playable storage medium.However, the benefit of that extra storage capacity is partly offset by the camcorder's larger size. Internal hard disk drives (HDDs) are built into the camera body itself and can store a significant amount of data, depending on their size.Memory cards come in a range of capacities, from 8 gigabytes to about 16 gigabytes. Because flash memory and memory cards are so small yet hold so much, they have enabled manufacturers to shrink HD digital video cameras and to speed up their operation.While it's more time-consuming to preview and transfer footage with the time-based tapes, they have the advantage of being their own self-contained storage mediums, and they're easy to transport.
MiniDV tape is similar to other tape mediums.
