Similar to S-VHS, Hi8 used improved recorder electronics and media formulation to increase the recorded bandwidth of the luminance signal. The luminance carrier was shifted from 4.2 MHz for regular 8-mm up to 5.7 MHz for Hi8, and the frequency deviation was increased to 2 MHz from the 1.2 MHz of standard 8-mm.
To facilitate digital recording on existing Hi8 video cassettes the helical scan video head drum spins 2.5× faster. For both NTSC and PAL Digital8 equipment, a standard-length 120-minute NTSC/90-minute PAL Hi8 magnetic tape cassette will store 60 minutes of Digital8 video (Standard Play) or 90 minutes (Long Play). There are 90-minute versions ...
DV (from Digital Video) is a family of codecs and tape formats used for storing digital video, launched in 1995 by a consortium of video camera manufacturers led by Sony and Panasonic. It includes the recording or cassette formats DV, MiniDV, HDV, DVCAM, DVCPro, DVCPro50, DVCProHD, Digital8, and Digital-S. DV has been used primarily for video ...
The camera imaged in 410,000 pixels with horizontal resolution of better than 530 lines. During the mid-1990s, Sony dropped Hi-8 in favor of the emerging DV format, and as a result the VX-3 was discontinued in September 1995.
Video capture is the process of converting an analog video signal—such as that produced by a video camera, DVD player, or television tuner—to digital video and sending it to local storage or to external circuitry. The resulting digital data are referred to as a digital video stream, or more often, simply video stream.
NightShot Plus switch on a Sony Handycam DCR-HC40E. Select flagship Sony Handycam models feature infrared night-vision dubbed NightShot (sometimes referred to as "NightShot Plus" on some models), which utilizes an infrared light-emitting diode and an infrared filter that is mechanically attached and detached to the sensor in order to enable the camcorder to record video footage in complete ...
The camera also has a 3-step ND filter switch allowing greater control of how much light can enter the camera for maintaining a shallow depth of field or giving a softer appearance to motion. For one hour video shooting in 4K the camera needs about 32 GB to accommodate a data transfer rate of 50 Mbit/s. The camera's MSRP in the US is US$2,000. [8]
To transfer video to a computer the camcorder must be connected with a USB cable. Most camcorders require using an AC power adapter for this operation. The sound of moving magnetic heads may be heard in the recorded video when recording in quiet environment.
