Looks like we have to cover much, we have now started!
When you do your own video production, one of the most important equipment you need to start investing in an HD (high definition) camera. This article describes the things that you will consider before purchasing or if you already bought one, this guide to learn about your device. During your post-production phase, it is very frustrating to know that is not your shoe size good as expected. Sometimes the pictures are larger, the color is so rich is the color keying is not as smooth, and a lot of different things you have no idea best buy 14 megapixle video camera. Finally, after fighting and accusations of your video editor, you came to the conclusion that the camera’s fault! You must have seen some of the critical functions of the camera. Let’s talk about them one by one.
Interlaced or Progressive
Interlaced and progressive will tell you how the image is refreshed on the screen. Progressive is easier to understand, is a frame at a time, that’s it! But with the interlaced frame is in pieces. Imagine the cathode ray tube scanning the screen line by line. In progressive, do the lines one after another without skipping. It is not hard, but a Russian inventor has developed a way to even and odd lines without much loss of quality for which the bandwidth to half skip. The downside, of course, the flicker you see on your standard television. Go ahead, look closely at your TV screens and you will notice two bands. This is how interlacing works.
So, you see 1080p, 720p, 576i in your HD camera. But one may wonder what the numbers for the stand personnel. 1080, 720, and much more variety of different curves, represent the vertical lines. So if you 1080p, it means that the camera with 1080 progressive vertical lines are recording. And there are more scan lines of the higher quality capture for editing.
Many HD cameras have different modes. So consider the purchase of a “mode which would go well with your projects.
SD, HD, NTSC, PAL
SD stands for standard definition, an old video viewing, storage and transmission systems such as color television was introduced. It has an aspect ratio of 4:3 and 480 interlaced lines. This is pretty much the best thing that you would be in terms of quality, slightly lower than this probably better on a screen instead of a TV best buy 14 megapixle video camera.
HD stands for High Definition, a video, which has a higher resolution than SD-HD, as has, however, are the most common view 1280x720px (720i) or 1920x1080px (1080i/1080p) in 16:9 aspect ratio. This is what they use to make movies and it makes a difference in the processing. You will probably find only by the quality when the images were shot on an SD or HD camera.
NTSC stands for National Television System Committee, which run at a frame rate of 30fps (frames per second) and 29.97 to be exact. It is common in Japan, the Philippines used, South Korea, Taiwan, Burma, and several Pacific islands.
PAL stands for Phase Alternating Line, which is used at a frame rate of 25fps and more widely around the world as NTSC.
SD and HD is save the quality of a single frame of HD affected more pixels compared to SD, while NTSC and PAL more about how smoothly the images belong together and the more frames are affected are the smoother the video would look like. But in NTSC and PAL, you just need to worry about is which country they used to and do not mind the other details. There is not much difference in frame rate anyway so no one sees the difference. However, PAL is superior because it is the most problems, the NTSC will have answers.
DV, HDV, DVCAM, DVCPRO
DV stands for Digital Video, a kind of video recording system that works with a digital rather than analog video signal. This has become the standard for home and semi-professionals and independent filmmakers to analog for their quality in comparison best buy 14 megapixle video camera. HDV stands for High Definition, a kind of video recording and playback. It is much better than DV 480i, it is acceptable to the professional production machining. The two main versions of its HDV 720p and 1080i HDV.
DVCAM stands for Digital Video Camera, a professional version of DV, the 50% faster with 50% wider track, so that the risk of failure errors. One of the features of this format is the ability to lock audio. You will notice that the inclusion of DV on several generations of the sound off-sync in DVCAM, this does not happen cause.
DVCPRO is designed for Digital Video Cassette Professional from Panasonic specifically for Electronic News Gathering. It has a wider track compared with DVCAM and uses a different type of tire.
These are video recording system format. Since DV has become a more advanced system that better quality. If you are in relation to parties or making an independent film with a small budget, but you can with DV. It is acceptable in terms of quality and price. But for the professional production, the format starts with all HDV to DVCPRO. You need this for broadcast quality output, such as television, commercials and likely to major events that have a high quality standard you have.
Y: Cb: Cr
Sometimes you are in the contract numbers that follows to see 4:2:2, 4:01:01 and 4:02:00 views. This tells us how much color information is stored in the recording. Y is the luminance (brightness), Cb is blue minus luma (BY) and Cr is red minus luma (RY)
* 04:02:00 sampling for DV and DVCAM (PAL)
* 4:1.1 sampling for DVCPRO25 and DVCAM (NTSC)
* 04:02:02 sampling for DVCPRO50 and DVCPRO HD
Consider the sampling 04:02:02 when compositing, effects and have realistic graphics. It has the highest color information compared to the others. This also explains why most difficult in the DV format to green / blue screens. It’s because it does not work enough color information.
CCD and CMOS
CCD stands for Charged Coupled Devices, which converts light into electrical signals. Most consumer cameras have a few chips or 1CCD. But professional 3CCD cameras, one chip for each color: red, green and blue. And when it comes to CCD, the bigger the better, there are 1 / 4 inch, 1 / 3 inch and 2 / 3 in. CCDs. Even with the same pixel count, larger CCD always results better photos.
CMOS Complementary Metal Oxide Semiconductor, is an alternative to the CCD. They allow more individual light sensors, a larger dynamic range lighting and are less sensitive to vertical lines (it is the vertical lines when you see a camera on a light source point).
Basically, the above to determine the richness of the incoming light, you should purchase a 3CCD or CMOS camera to consider for a professional look is recommended.
4:3 or 16:9
These are used the most common pixel aspect ratios. But there are other relationships in the early days of video production, it was almost two standards.
Academy Ratio 4:3 or the SD and standard television, while 16:9 is the international standard or widescreen format of HDTV best buy 14 megapixle video camera. Consider when choosing an aspect ratio, what the screen video plays. Professional cameras have these two modes, you can switch between the two, but now since the wide-screen LCD TVs and switch to widescreen format and used.
Lens
There is not a lens for any purpose. Most professional videographers with a telephoto lens is biased against each other, and that is very wide. However prosumer cameras have this option because their lenses are built so that it is not wide enough zoom, but there are wide-angle adapter.
To be sure, check how you wear your contact lenses at the extremes. If you zoom in, you can roll (verticals are curved at the sides) or vignetting (dark corners). You can tell the lens is good if it minimizes these properties.
Audio Input
Let me first orient you the type of audio inputs to video cameras. First we have the “minis” that you in your iPod. These are derived as a TRS (tip, ring and sleeve) from the conductive parts. They come in mono and stereo with the likes of 2.5mm, 3.5mm, and 6.3mm. All videos must be at least this kind of audio input. Second, we have the RCA (Radio Corporation of America) audio inputs to be on the back of your TV and VCR red, white or black most of the time. Third, the XLR connectors, which are the ones you see when you have a handheld microphone from the corded have. See below the microphone after you? That’s how it looks in the camera. These are the ones used by professionals.
When buying a camera, always a built-in microphone. But it is omnidirectional, or it can pick up all ambient noise, even those who do not like, such as background noise. So, should you buy professional microphones. And these microphones or stereo jacks (ie Laval Irish or lapel) or XLR connectors (ie, shotgun microphones). So a better HD camera capable of dealing with the audio equipment, because you need it.
Input Output
We have component, RCA, S-Video or FireWire. When editing, you probably need FireWire, but today most HD cameras, this so you do not have to worry about. Other inputs are analog outputs do not bother about it when you show all the RAW images directly to a TV or during an event. FireWire is very useful in the treatment site because it connects directly to your laptop, provided you have a FireWire input. You can also submit your videos edited on DV tape with FireWire best buy 14 megapixle video camera. And there you have it. I hope that next time you are walking into a store looking for an HD camera, you should not be confused with the information and you have more confidence in the purchase.
