HD video (HDV) or High-definition video in general, refers to whichever video system of higher resolution in contrast to standard-definition Standard-Definition(SD) video, most normally at display resolutions of 1920×1080 (1080i or 1080p) or 1280×720 (720p).
High-definition (HD) uses a wide-screen system format, presenting a thoroughly clearer picture than the conventional. Each line in HD also encloses more information than standard formats. HD is passed on using digital technology. Given the fact that it takes a vast amount of coded information to stand for a visual image—engineers believe HD will require approximately 30 million bits (ones and zeros of the digital code) per second—data-compression methods have been urbanized to lessen the number of bits that need to be sent out. With these method, digital systems is required to incessantly transmit codes only for a panorama in which images are shifting; the system can compact the chronic codes for images that remains matching (such as the background) into a distinct code.
So what does shifting to a high-definition camcorder truly mean in terms of excellence?
This simply means that you can see a lot more details. This underlines the fact that if you shoot video in HD, it directs you to a much more realistic looking video. HD does have its drawbacks, though. While the HD frame is indisputably sharper, there can be trivial, but noticeable patterns of square blocks (pixelized) on your picture. This is on the grounds by HD’s superfluous compression: In order to squeeze high-definition video onto the equal storage that standard-definition MiniDV camcorders use, the video has to be a lot more heavily compressed, and this leads to your picture being pixelized. But that’s a very negligible issue. A lot of people won’t even notice the blockiness. When you start to do compositing though, then it becomes a problem right there. This is where you swap a color with a different image, so you can carry yourself from a plain green background to a war zone or at the top of Mount Everest. This pixelization means that the ends of spot of color to be detached aren’t obviously defined, which can lead to a “halo” result.
Who will benefit the most from HD camcorders?
For people who don’t want to miss any important event in their lives; a daughter’s dance recital or graduation, weddings, adventures, a spontaneous news-making event, or an amateur documentary film, nothing captures that perfect moment quite like high-definition video does. Along with HD camcorders, you can shoot hours upon hours of video in jam-packed HD resolution, with entertaining video effects and ocular zoom lenses up to 12X.
So if you want to be someone who puts everything he sees on files or wanting to be the next Tarantino, then HD camcorder is a must for you to have.
There’s HD camcorder out there for everyone. The first decision you want to make is whether you want a tape camcorder, mini-DVD model, or one that stores footage on a drive or a memory card. Each has its advantages and disadvantages.
Advantages and Disadvantages of HD Camcorder
Taped camcorders like the Canon HV20 – HDV Camcorder ($1,016.28 vat included) may be old-school technology but it is a proven technology. Besides, tapes are cheap and easy to archive and putting footages on a computer is pretty simple too. They also work well with any model-editing program and in slower PCs. The main drawback is repeatedly buying tapes and it degrades over a period of time.
Many DVD camcorders like the Panasonic VDR-D310 Camcorder ($699 MSRP) records footages on small DVD disks. This is convenient for instant gratification. But mini-DVD disks are pretty expensive in contrast to tapes. You also will get the same qualities of video footage on tape-based and DVD-less or tape-less camcorders.
Tapeless and DVD-less camcorders such as the Sony Handycam HDR-SR12 Camcorder are the way of the future as more and more major vendors are switching to hard drive and Flash storage based models. Although this is quite expensive ($1,124.99). These don’t require you to repeatedly buy tapes or mini DVD disks. But you need a plenty of space to off-load your storage. Hard drive based models offer more storage capacity (which in this case, 120GB) but also susceptible to long-term wear and tear use than flash storage hard drives. Camcorders that use SD or SDHC cards like the JVC GRD70 MiniDV Camcorder ($500.00 Retail) can be a great option. You can just pop the card and insert it into your computer and transfer the file without hooking the camcorder to the computer.
Format qualities are just a few of the aspect you should look into when buying a HD camcorder. Some opt to focus on the screen and optical zoom ability of the device. A drawback from camcorders with larger screen is that it lessens battery life. You don’t want to run out of battery in the middle of shooting something important. For optical zoom though, this can be very vital since we all want to focus something beyond the reach of our eyes. Others are also looking at the camcorders weight and consider it as a key factor for portability, but a lightweight camcorder won’t do much good if it holds too small for your hands. Too light camcorders can also affect the stability of your shoot.
High definition camcorder today is at its peak in terms of marketing. Some opts to have it because of better details and actuality, some for convenience and portability. But whether you choose to have it for whatever reason, surely the HD camcorder is almost a necessity. It can be quite expensive but thinking of using it for a long time compensates your loss, and surely it will still be a good return.
