◇英雄问出处对于DV(Digital Video)的定义,一般是指DV摄像机,但从广义上来说DV影像技术包含三个方面的内容:1.DV摄像设备(数字化拍摄);2.数字视频文件的存储与传输;3.个人电脑上的非线性后期编辑。很多人只注意到了DV摄像机的优势,而DV影像制作的优势应当说是这三方面技术发展的有机结合,DV影像技术使影像制作达到了真正的低成本,操作方便,更加简单明了。 90年代初,飞速发展的数字音视频技术为影像数字化奠定了基础。当时有近50家电器、电脑厂商成立了“高清晰数字录像机协会(HD Digital VCR Conference)”组织,他们为家用数字摄像机制定了一个统一的规格:民用级别的Digital Video磁带标准为带宽6.35mm.磁带尺寸为4.8cm×6.6cm×1.22cm,录像时间为60分钟(LP模式为90分钟),被称为Mini DV。 1996年,索尼、夏普等家电巨头开始正式向市场推出Mini DV格式的摄像机。由于采用新技术的初始成本较高。起初DV摄像机的高价并没有被认可,而且不管怎么说这也仅仅是一种家用产品制式,不过经过一段时间的推广,一些独立制作人认识到DV摄像机在技术上的优势,开始用它来制作一些记录性质的作品。随着使用的人越来越多,一些DV拍摄的优秀低成本作品显露头角,很多人认识到DV原来也可以做出不错的东西来,随后DV开始风靡全球。
◇ hero asked where the definition of DV (Digital Video), generally refers to the DV camera, but broadly speaking DV video technology includes three aspects: 1. DV video equipment (digital camera); 2. digital video files Storage and transmission; 3 non-linear personal computer editing. Many people only noticed the advantages of DV cameras. The advantages of DV video production should be said that these three aspects of organic development of technology, DV imaging technology to make the real low-cost video production, easy to operate, more simple and clear. The early 90s, the rapid development of digital audio and video technology for digital imaging laid the foundation. With nearly 50 appliances at that time, computer makers set up the HD Digital VCR Conference, a unified specification for home digital camcorders: the civilian-grade Digital Video tape standard has a 6.35-mm bandwidth. Tape size 4.8cm × 6.6cm × 1.22cm, recording time of 60 minutes (LP mode for 90 minutes), known as the Mini DV. In 1996, home appliance giants such as Sony and Sharp started to formally introduce Mini DV format cameras to the market. Due to the higher initial costs of adopting new technologies. At first, the high price of DV camcorders was not recognized, and in any case it was just a household format, but after some time promotion, some independent producers realized the technical advantages of the DV camcorder and started using it Some record nature works. As more and more people are using DV, some excellent and low-cost DV works have been revealed. Many people realize that DV can also make good things, and then DV has started to swept the world.
