Tape DV: The price is relatively cheap, but the later compression is inconvenient.

The main advantage of tape DV lies in its versatility. Whether Sony, Panasonic, TDK and JVC DV tapes, basically any brand of DV can be used. The price is also cheaper. It only takes about 20-25 yuan to buy a DV tape, and you can basically use it for 5 times. After calculation, an average of a few dollars can shoot 60 minutes of DV images, which is more valuable.

The main deficiency of tape DV comes from the inconvenience of later collection, compression and editing. For ordinary home users, the post-editing of tape DV has higher requirements for computers. Generally, more than 5 12M memory, more than 40G hard disk capacity, and 1394 card and 1394 cable are needed for transmission and acquisition. The configuration cost is not very high.

Of course, the most convenient thing is to send the DV tape directly to the store for conversion and burn it into a DVD disc for storage. At present, in Guangzhou Computer City, it takes 25 yuan to convert a 60-minute DV tape into DVD.

In terms of cost performance, ordinary tape DV is very rich in brand, model and function price from low-end entry to high-end machine in the current market, meeting the needs of all kinds of consumers.

DVD camera: Post-editing is convenient, but the price of CD is high.

One of the biggest advantages of DVD camera is that it is convenient to collect and compress later. Because DVD is stored and compressed while shooting, there is no compression link, and you don't need to buy 1394 card for collection. It can be sent directly to the computer through USB cable, saving a lot of time for later editing.

Of course, the editing of DVD camera is not as good as that of tape DV, and its main disadvantages include: First, the life of laser head, especially when shooting continuously, the body of DVD camera is very hot, which will greatly shorten the life of laser head.

The second is the price of accessories. At present, the price of reusable DVD discs in the market is between 80- 120 yuan, which is much higher than the purchase cost of a single DV tape. In addition, it may be inconvenient to buy DVD discs when traveling, because it is best to buy many discs in advance before traveling.

In terms of cost performance, the price of DVDDV console has dropped sharply with the collective launch of manufacturers, but it is still higher than the common DVD DV on the whole. In addition, the recordable DVD discs that DVDDV must buy later are also expensive. Take Sony brand 8CM disc as an example, the purchase price is about 120 yuan.

Hard disk DV: The post-production is simple, but the service life is short.

The advent of hard disk camera not only solves the problem of DV tape, but also makes hard disk smaller, that is to say, the product shape can be smaller and smaller, which has certain advantages in portability and fashion, in line with the current development trend of pursuing smaller size.

Compared with DVDDV, the failure rate of hard disk DV is relatively low, so it is not a big problem for hard disk DV to shoot continuously for a long time. Similar to DVD camera, the post-production of hard disk DV becomes easier, especially the acquisition and compression, because the compression has been completed at the time of shooting, and the acquisition is also completed through USB cable transmission.

At present, the capacity of 30G is equivalent to the DV capacity of 3 tapes. If the shooting time is long, it is better to boot to the computer hard disk as soon as possible. For hard disk DV, the biggest shortage is the service time. Some insiders suggest that the service life of DV hard disk needs to be improved.

In terms of cost performance, hard disk DVD is the latest in the market, so there is the biggest room for price reduction. But because it is a hard disk, users don't need to buy any storage media, which naturally saves the cost. The post-production of hard disk DV mainly depends on data cable to transfer the contents of hard disk to computer, and then burn it into DVD for storage.

shopping tips

DV purchase is practical first.

In the digital DV market, mainstream manufacturers led by Sony, Canon and Panasonic have successively introduced the concepts of DVDDV and hard disk DV, and even threatened that DV has entered the era of diskless tape. However, we suggest that you should not rush to buy those new multifunctional DVs, but should focus on the models that have been on the market for about a year and a half, because these products have withstood the test of the market and time, and the quality is generally good, but the price has dropped a lot.

Although DVDDV and hard disk DV are very easy to use, the price of the host is still quite expensive. What's more, DVDDV and hard disk DV are still new things, and there is still considerable room for price reduction in the future, and the follow-up accessories they use, such as recordable DVD discs, are not cheap. Therefore, most ordinary users should choose and buy traditional DVD-DV according to their own economic strength and expected frequency of use, which accounts for more than 80% of the current market.
