CHOOSE THE HD VIDEO CAMERA
If you decide to buy a camera by the summer, and decide that this camera must be highly accurate, then the main choice that confronts you is the choice of camera type. Today, the world is dominated by five main classes of digital video cameras, which differ from each other in information carriers.
The camcorder has already become as ordinary a home media device as the TV
Here they are – recording on MiniDV tapes, on a DVD-ROM, on a hard drive, on a flash memory card, and finally on a flash memory such as SSD.
Aspect ratio and aspect ratio for various video formats
However, for those who still have not decided whether to buy a camera with the ability to record high-definition images, we explain the difference between these video formats. If you use a regular TV with a diagonal of up to 29 inches, then you probably will not need an HD camera, since you will not see any advantages of high resolution on a small TV. In order for a high-fidelity signal to show itself in all its glory, an LCD or plasma TV with a diagonal of over 37 inches is needed.
The aspect ratio of high-definition video formats is 21: 9, 16: 9 and the standard format is 4: 3
The source of the audio-video signal is also important, since it must support HD playback. Today, there are two ways to play video recorded by a high-precision camera, the first is to record your home video on Blu-ray discs, and then play it through the appropriate player; the second is to upload these files to a media player with a hard drive and watch directly from it. In both cases, the video should be mounted in a movie.
As you know, recording to tape, or rather to a MiniDV cassette, is the oldest recording system we know today. The technology has been perfectly worked out and has been used for quite some time, both in amateur video and in semi-professional. The cassette itself has undergone not too big changes since the time of VHS-VCRs, all the same film. Only now the cassette has become smaller, and the recording on it is digital.
A plus. It may not seem strange, but this system gives, today, one of the clearest pictures, because the compression ratio of digital video is the lowest when digitizing.
Minus. The main difficulty in working with “cassettes” is the difficulty of dropping video files from the camera to the computer, due to the huge size of the latter. Yes, and reformatting, and editing files MiniDV-cameras requires a computer with fairly strong parameters.
Canon LEGRIA HV40
The Canon HV40 is one of the best in its class in terms of picture quality, it has many improvements and ease of use. Video in HDV1080i format is directly recorded on standard MiniDV tapes. To obtain excellent picture quality, the camera uses a 2.96 million pixel CMOS matrix. As a second storage medium, the camera uses a miniSD memory card for which you can take pictures in a maximum resolution of 2048×1536 pixels. The camera has a Pictbridge interface that allows you to print photos directly without using a PC, as well as a USB 2.0 interface. .
The Sony HDR-HC9 camcorder is a fairly affordable High Definition 1080p camera. It has a 3.2 megapixel sensor. Video recording is made in a resolution different from Full HD, although 1440×1080 pixels. The camera is distinguished by a variety of manual settings for color, focus and other parameters. Optical zoom is 10x. Type of memory card: Memory Stick Duo Pro.
As soon as a recordable laser disc appeared, the idea immediately appeared to use it as a carrier for video cameras. Due to their size, cameras use a small, 3.5-inch DVD-ROM. This disk is limited (in comparison with a standard disk) by volume. The technology of saving information has some difficulties, for example, in many DVD-cameras, with the final burning of the disc ─ finalization, connection to the main power of the camcorder is required. Finalization requires high energy consumption, and it is unreasonable to carry it out on batteries. The recording quality on DVD media is almost as high as on MiniDV.
A plus. After recording the video, you can watch it almost immediately on a DVD player.
Minus. Limited recording time per disc and the need for finalization.
The Canon HR10 uses Instant AF and Optical Image Stabilizer Super Range. The high quality video of Canon’s HD camcorders comes from the excellent Canon HD Video lens, Canon CMOS sensor and DIGIC DV II processor. Recording format AVCHD.
The camcorder with a DVD-ROM as a carrier of Sony HDR-UX7, capable of shooting video in HD-resolution (1920×1080), has support for x.v.Colour technology that improves image color, has a digital HDMI interface for transferring video information to a computer or TV. The camera has a 2.7-inch rotating LCD touchscreen monitor. Sound recording is in Dolby Digital 5.1 format.
