Which storage media do you want to buy DV?

DV uses tape, CD-ROMs, hard disks, flash memory, these kinds, at present, home DV should be a hard disk machine is more practical and economical, but also the most popular, the main advantage is that the transmission is convenient and fast, large capacity, and ** has been reduced to a reasonable area, the disadvantage is that the image format is compressed, the picture quality has declined, more than 3,005 plateaus can not be used normally, and the advantage of tape is to keep the original image question is better, the disadvantage is that the file size is large, the acquisition is troublesome, and the disc DV has tended to be marginalized, The reason is that the shortcomings are too obvious, such as the short recording time of the CD, the follow-up investment is large, and finally the flash memory type of home DV should be the most promising DVThe advantages are light weight, small size, not afraid of vibration, and fast access speed. Of course, there is no such thing as a picture quality that will degrade **.

In addition, because it is a card record, there is no physical mechanical transmission, power saving, and the heat generation is minimal. So it is a good kind of record, but due to the limitations of the current price segment chip manufacturing technology, the card is not like the hard disk can do more than 100 g of capacity, and the large capacity of the memory card ** is several times more expensive than the hard disk, and now it can not replace the position of the hard disk drive, but with the development of science and technology, it is only a matter of time to replace the hard disk drive.

of hard disks. Because hard drives are now quite reasonable.

The same is true for flash.

But flash memory is sacrificing capacity in exchange for good shock resistance.

The hard disk type is more recommended for home use. Cost-effective.

If you work, you still have a DV belt.

The DV belt can be changed. And the picture quality is better.

And the DV belt is arguably the cheapest way now. It is suitable for people who need post-editing.

After all. It's painful to record how long the world has to turn.

As for how to choose this, the author does not dare to assert that in fact, these four storage media do have their own advantages, and sometimes even learn from each other's strengths and weaknesses. So the HDV, which has just been launched for two or three years, is it about to be replaced by a new *** medium? Will memory cards and microhard drives become similar products?

The author can only take a look at the future trend based on experience.

1.Dedicated to the field of calling: the last position of tape.

As we all know, DV tape technology is mature, but there is not much room for development. Technological maturity means better stability, and this not only means the stability of technology, but also the stability of the group. Because a large number of professional and amateur personnel have become accustomed to the operation of DV tape, coupled with the introduction of HDV technology, huge material storage, and complex workflow, it is believed that DV tape will not prematurely retire from the stage of history.

2.Civilian sector: Optical discs are the mainstream.

When it comes to optical disc storage, we can't fail to mention Sony's Blueray DiskIn fact, the use of blue violet light instead of ordinary red light for data reading and writing, because the wavelength of blue light is much smaller than that of red light, so it can imitate the defeat of Kai to gather in a smaller range, so it can also record more data on the same disc (ordinary *** data storage capacity, while Blu-ray disc can reach 25G).Earlier, the well-known Sony PS3 also announced full support for Blu-ray technology, and it is conceivable that the optical disc medium will vigorously promote the concept of home entertainment.

However, at present, due to the high manufacturing cost of Blu-ray discs, Sony has no choice but to use ***+r DL (double-sided single-sided disc, the data storage capacity is 2 times that of ordinary ***) as a transitional product for Blu-ray discs. From the above analysis, we can see that optical disc storage will be the most important technology in the civilian field in the future.

3.Future: Hard Disk Cameras vs. Memory Card Cameras.

A memory card is equivalent to a high-speed memory, while hard disk storage is more like a computer's hard drive. Therefore, in terms of capacity, the capacity of the memory card is less than the capacity of the hard disk at the same cost. However, the memory card is semiconductor storage, without any mechanical device, in a variety of high and low temperature, wet and dry and other harsh environments, professional memory cards (such as Panasonic P2 card), will not be affected.

With the development of semiconductor technology, memory cards may occupy a more mainstream position in areas such as news gathering. Hard drives, on the other hand, can be used as a digital storage solution, for example in the production of shows.

As you can see from the above, the author did not say what machine to choose, and put this choice in your hands, you can choose according to your own requirements, but after understanding the difference between the media, it is best to understand the coding format of ** and the knowledge of the computer in terms of editing. And for the purchase of what machine to choose,How to choose the machine,A lot has been written in the original post,You can first look at the essence of the sticker,And then slowly from the oldest post to the nearest sticker,Generally speaking,The initial post in this regard has more instructions。
