General tips for
1. Type of digital video camera
The type of digital camera depends on the type of media on which footage will be recorded. Consider the most suitable types of camcorders for the family:
DVD. A characteristic feature of this type of camera is that data recording is performed on DVD, or rather a mini DVD disc. Video recording takes place in MPEG2 format with a resolution of 720x576.Thanks to this type of media, you can immediately view the captured video on a DVD player. But this type of video camera is not the best option for a family camera, since there is the following type.
Blu-ray. This type of digital camera records video on a Blu-ray disc( mini-BD) so you can record video with a resolution of 1920x1080 in Full HD quality, however, the duration of the video will take no more than an hour. This option is much better than its above-mentioned counterpart, but it costs an order of magnitude more.
HDD. These camcorders allow you to record video on the built-in hard disk in MPEG2 format with a resolution of 720x576.In addition, there are HDD cameras that support the recording of widescreen video( if AVCHD 720 or 1080 lines are available).Undoubted advantage is that on a hard disk depending on its volume, you can record up to 10 hours of video in HD format. Of the disadvantages is worth noting the high cost of cameras with support for AVCHD.
Flash. The most common and convenient type of video camera. The camera uses Flash memory to record and store data. Cameras of this type can have both built-in memory and a special slot for it, thanks to this you can freely change the filled maps, as well as easily copy video from them to a computer or laptop. The advantage is also that these cameras have a compact form and light weight, which is very convenient for transportation and carrying with them.
2. Type of digital media
As you may have guessed, the type of video camera assumes the appropriate type of media. The following media are used in video cameras:
• Optical disk;
• Hard disk;
• Flash memory.
When choosing a camera, give preference to a medium that you will be more comfortable to use, but in turn we would advise a camera with a slot for Flash cards.
3. Resolution of the recorded video
The higher the video resolution, the better it will be. In addition, if you watch recorded video on a widescreen monitor or TV, it's necessary for the camera to shoot video in HD quality, or even better in Full HD.We also recommend that you purchase a camera that shoots video with a resolution of not less than 1440x1080.
Here it is worth mentioning about the image format. As you all know, the widescreen picture is now in fashion, so we recommend that the camera shoot the video in a ratio of 16: 9.
4. LCD screen
For the convenience of video shooting is very good, if the camcorder will have an LCD screen. With this screen, the operator will monitor, and monitor the progress of the survey. It is desirable that the LCD screen has the ability to rotate in a range of 180 to 270 degrees. New models of cameras are equipped with a touch screen, which makes the management of video shooting more convenient and interesting.
5. Shooting Modes
If your digital camcorder has the ability to select shooting modes, this is a definite plus. The most popular modes of shooting:
• Twilight mode;
• Sunrise and Sunset modes;
• Fireworks mode;
• Landscape mode;
• Beach Mode;
• Snow Mode.
Thanks to the availability of these modes you can get high-quality video when shooting in the appropriate environment.
6. The number of frames per second
The higher this figure, the more smooth and natural the image will be. Modern video cameras support video with a frequency of 25 to 60 frames per second. The most optimal figure for a camera is 50 fps.
7. Zoom
Zoom is the ability to visually zoom in or out from the objects you take to avoid getting closer. With the help of the magnification, you will be able to zoom in on the desired object so that it is good and fully captured in the frame. But with a strong increase, the image quality will deteriorate noticeably.
Buying a camcorder, give preference to optical zoom, and not digital, because with the first option, the increase is due to optics, and in the second variant due to cutting the edges of the frame.
Choosing a digital video camera
After we have reviewed the so-called basics that you need to know before buying a digital video camera, now let's look at the minor functions that will be very useful.
Streaming via USB.For this feature, the camera must have a built-in USB port, with which you can connect the camera to the computer and adjust the streaming of video from the camera.
Connect an external hard disk. If you shoot a long video, then you need a lot of space for it on a digital medium. This problem can be solved by the possibility of connecting an external hard disk to the camcorder.
Photo mode. With the help of the photo mode in the camcorder you can not only shoot the video, but also take photos, which will make your camera more versatile. With a video camera, you no longer need to carry a camera with you.
Macro photography. The presence of macro mode in the camera will make it possible to shoot small objects close-up.
Flash. The presence of a flash in the camcorder is a very necessary thing with which you can shoot in low light or in the dark.
Night mode. This mode will make it possible to shoot at night, but note that the quality of such a shoot will be bad anyway.
Battery. Pay attention to battery life in stand-alone mode and during shooting. If you shoot a lot, you may need to purchase an additional battery or replace it with a new one, a more powerful one, which will hold more than 4 hours.
Manufacturers. Popular manufacturers of cameras are the following companies:
• Sony;
• Canon;
• Samsung;
• Kodak;
• JVC;
