A type of video recording system that works digitally is called as digital video. The captured images are recorded on tape then distributed on optical discs, but the recent camcorders record digital video directly on to the hard disks. Interlaced and progressive scan are two of image capture formats in Video Cameras. Compared with a digital videos, a 35 mm films, are significantly higher cost, since the captured images can be viewed on location without processing.
Because of the similarities they share with film progressive scan camcorders are generally more desirable, but progressive scanning Video Cameras as tend to be more expensive than interlaced. No degradation in quality if digital video are to be copied, as many copies are generated it will be as clear as the original first generation. An exclusive device name as Non-Linear Editing station is built to edit the digital video and audio. Recently a personal computer has the proper hardware and software also can be used for editing of the digital video. In early 2000s they are spread into the most of developed countries and this technology is used for movie making, modern mobile phones, Internet media distribution, including streaming video and peer-to-peer movie distribution, video conferencing systems. While editing DV video is not compressed beyond its own codec, file sizes resulted are not practically for deliver to optical discs or over the internet. Codecs such as MPEG4 and Windows Media are the most widely used formats to overcome those problems.
The highest resolution for digital Video Cameras generation is 33 mega pixels at 60 frames per second have been demonstrated in 2005, then in 2006 the Cordin as the world leader in ultra high speed imaging technology launched the highest speed in industrial and scientific the high speed cameras that are capable of filming 1024x1024 video at up to 1 million full frame rate in color or black and white.
For scientific applications Streak camera systems developed with modern technology are available. Phoenix Video Cameras offer various possibilities of high speed applications in short, middle or long wave infrared. Another ones such as QWIP, InGaAs InSb Detectors have capability to acquire images with a frame rate of up to 30 KHz in the wavelength range of 900 nm to 10 µm.
