Digital cameras use lithium batteries in the correct

To the digital camera battery is a bit of learning, do not understand the basics of charging, the battery charge is not only bad, when shooting a short time, will shorten battery life.

 1, DV camera battery charging time
Battery charging time can not be generalized, because different battery capacity, charge current is different, etc., will affect the charging time. Digital camera comes with a charger, the charger has charging status indicator, such as the just put the battery charging, the indicator lights, and other battery to a certain extent, the light will change color or turn off. Then charge the battery basically good, but if we really want the battery is fully charged, it will take longer because as. Large-capacity battery charging time is long, my experience is that if there are two batteries to charge, first charge capacity of a small, high-capacity rechargeable battery, charging and high-capacity batteries can go to sleep the next day will charge a good morning.

 2, DV cameras can be used with rechargeable battery
Early cameras generally use nickel batteries, long charging time the battery if the battery in the crystallization of the liquid will prevent the charger a full charge. Therefore, the discharge must be fully charged or on a regular basis. Now digital cameras use lithium batteries, we can easily charge the battery at any time, we did not like the nickel batteries, as trouble, not necessary time to fully boot and then can not use lithium batteries.

 3, DV camera battery life
On the life of lithium problem, say many, such as lithium can only charge 300 to 500, then you need replacement. Correct to say that the life of lithium and the number of charge cycles completed, and number of charge cycles is not directly related. Simple to understand, "a charge cycle" refers to the full battery of all power used by the air, then air charge to the full process. Therefore, the charge number of times, and the actual battery charge cycle is not reciprocal. For example, a lithium battery's charge cycle can be used for video camera use 10 hours (note that a charge cycle, not one charge), three hours after actual use, the battery is full of a battery; use five hours later, once again filled with a battery, two electric charge at this time though, but a charge cycle is 10 hours of battery charging time to add up to only two 8 hours, therefore, the third piece of the battery is fully charged after using two hours before completed its charge cycle.
As you drink a glass of beer specified, you drink a cup of follow-up one-third fill up, and you can not say that drinking a cup, a cup of beer, regardless of whether you continue to add, once you drink a third cup, then drink three times to complete the assigned task is "a cycle." So the correct argument lithium battery life is 300-500 charge cycles.

 4, DV camera battery charging times
In fact, with the above explanation, say the total number of charge cycles a battery does not make sense, however, each completed a battery charge cycle, the total capacity will be reduced that period to reduce the magnitude of the size depends on how the quality of the battery. Generally high quality battery charge cycle many times, will still retain the original power of 80%, for example, can reach the upper limit of 500 charge cycles, which is still two or three years a lot of lithium as usual reasons; that the poor quality of some lithium battery, the charging cycle may be up to the lower limit, such as 300 or less, so this battery will make people feel a more obvious "less and less resistance to using the." In any case, DV camera to use Lithium batteries eventually need replacement.
If a high-quality lithium battery charging cycle is 500 times, and we used half of the charge each time, it can charge the total of 1000 times. Therefore, the lithium battery life and the total charge capacity, and the number of unrelated charge, rechargeable lithium battery is discharged or re-used with the charge for its life-span of less. Therefore, DV cameras use lithium batteries used to facilitate the main, with the use charge without fear of affecting life.

 5, DV cameras use lithium batteries Notes
One is not above 35 ° C above the environment or to use lithium batteries, the battery and do not save on the daily temperature is too high; two at low temperatures such as 4 ° C The following uses a lithium battery, battery time is reduced, and the low temperature environment may charge no power; third is if you do not often use lithium batteries, lithium best month to complete a charge cycle, that is, filling a deep deep release.

Digital cameras do need to install the UV lens

Buy digital video (DV), the need for a UV lens with it? What is the role of UV mirror? Let us know about UV lenses, UV English Utlraviolet (UV) abbreviation. UV microscopy main role is to filter out the ultraviolet light.
 UV mirror originated in the era of traditional film cameras, because the film to light in the ultraviolet-sensitive, ultraviolet photographs have a strong cast of local phenomena, so in front of the camera lens with UV filter out ultraviolet light to correct color cast. UV lens protection and because there is the role of the lens, such as to prevent dust, fingerprints, rain, snow and the pollution of the lens, so the general will on the camera lens with a UV microscope, and mounted on top of perennial not take off, UV lens basic become a necessity.
 Digital cameras use CCD light-sensitive device is not sensitive to UV, so UV lens for digital cameras, the main role is to protect the lens, so as dust, fingerprints or oil such as damage to the lens. Home video camera lens aperture is relatively small, buy a UV lens with a lower price, multi-layer coating diameter of 37 mm or so of UV lens also hundreds of dollars. There are also so-called market poor quality UV lens, in fact, an ordinary glass, the price of ten dollars or so. This lens is not UV coating, use of light will be reflected back into the lens part, and thus have an impact on quality. This, friends who wear glasses should be more able to understand, there are coated glasses and uncoated, coated glasses and good light transmission, basically do not feel the presence of the lens, there is no ordinary lens coating is different, often subject to interference from outside light to see clear, backlighting is particularly serious. If we put a DV to their non-coated "lens" is bound to affect the image quality.
Some friends asked, using the UV lens is not affecting the image quality of digital camera do? In theory, no matter how good the quality of the UV mirror or other lens attached, are more or less will affect the image quality, but good quality UV microscope imaging has little effect, negligible. We choose the UV lens, it is best to choose a professional camera store supplies UV coating on the mirror installed on the DV camera, the general single-layer coating can be, the common brand KENKO (Kenko) and HOYA (Hoya ). As a result, the lens in the lens under the protection of UV safer, dust, UV mirror files will be live, just clean up the UV lens on it.

Buy digital camera battery tips

Random House will use digital cameras with an ordinary battery, this battery time and only last up to two hours, a battery for the camera and then matching is necessary.
 1, the source of digital camera battery
 DV uses two main sources of lithium, a manufacturer of original products is DV, the other is the domestic parts manufacturers to produce alternative products. Battery performance and life from the point of view, the original product is still relatively good, but compared with the alternative product, its price is too high point. Domestic products, especially for digital cameras and digital cameras digital battery manufacturers produce more, product quality was mixed. There are several brands of the good, the quality of basic battery can be comparable to the original battery. Examination is the best brand direction, of course, the price is relatively expensive, and secondly, such as product wins, Sanger, REpower and so on.
 2, non-original battery price and performance DV
Now the price of domestic DV camcorder battery is relatively low, such as the price of the original standard battery in the $ 500-700, then made the same capacity alternative battery only 150-200 yuan can buy into. Although the alternative battery life and performance than the original almost, but the price is still high. DV in the purchase of these non-original batteries, we must be careful not to purchase counterfeit products, such as the aforementioned brands, such as direction, quality wins, etc. These batteries are generally no fake, the more signs the name of the original battery battery, the more fake and shoddy products. If the business claimed that his battery is the original goods, packaging and battery itself is a certain brand of DV and the same logo, but the price and other domestic alternative battery basically the same or even lower, then basically it can be concluded to be true . Use fake battery light does not work properly, such as the use of a power outage, use shorter time, a serious burn DV in the relevant circuit, so that backing is not clear or backing "great" price not to low battery purchase.
 3, to choose a large capacity battery
Optional DV battery, you should try to buy larger capacity. DV standard battery capacity is generally not large, the manufacturers are basically based on power consumption with a DV would be able to shoot two hours of continuous battery. If we buy domestically produced alternative battery, standard battery capacity, and do not choose the same product, at least choose more than twice in wife battery capacity. Such as the standard battery is 1200 mAh, we can buy a 2400 mA or larger then the.
 4, true, simple to distinguish fake DV Battery
We are talking about real, fake batteries, not included its own brand of domestic DV battery, just the name of the original battery for the production of bogus products under the banner. False appearance may be rough DV battery, say "may", because many false things to do than really still beautiful, ordinary users only through their appearance is difficult to judge the authenticity of; Then there try the weight of the battery, false the true capacity of the battery with the same battery of comparison, should be lighter weight, mainly because of the internal use of batteries can not. I have split off fake DV battery, its internal use of the batteries turned out to be four bad cell phone battery with a 3.6V square and then two parallel series of 7.2V, where the internal gap filling foam; the original battery, or brand made general use of alternative battery of high-quality imported or domestically produced single cylinder lithium batteries, so the same size batteries and will not leave the battery in the same weight.

Basic video editing software EDIUS features

The following passage is the official website of the software EDIUS evaluation: EDIUS nonlinear editing software designed for broadcast and postproduction environments, especially for news reporters, tapeless video production and broadcast and storage. EDIUS has a good file-based workflow, providing real-time, multi-track, multi-format mixed, synthetic, color keying, titling and timeline output capabilities. In addition to the standard EDIUS series format also supports Infinity JPEG 2000, DVCPRO, P2, VariCam, Ikegami GigaFlash, MXF, XDCAM, XDCAM HD (4:2:2), and XDCAM EX video material. Support for all DV, HDV cameras and recorders.

Words of this very professional, after a series of articles where we will only use words to introduce this popular professional software, set aside some of the less frequently used functions and not practical, so that we can learn "can." Although EDIUS is for broadcast and post production environments, but EDIUS very easy to use, easier to "learn", with one saying goes, is "very easy to use." Before, we believe that the video post-editing more difficult to learn, most people can not learn, and now with the computer hardware and digital cameras continue to upgrade, home video camera is gradually to the "tapeless" universal, this also solved the more difficult to deal with before. " acquisition "problem. "Tapeless" solutions not only capture the problem, also edited the video store has brought new changes, such as do not have to burn DVD discs, removable hard disk, memory card and so can be used to store and exchange.

 EDIUS so that we can have a relatively high profile of the computer under the premise of real-time, multi-track, mixed format editing and multi-subtitle and timeline output capabilities. These features in the past you want to achieve is very difficult, the need for expensive professional editing card hardware can support. In our future articles, these basic functions will be introduced. In addition, EDIUS can support many formats of video material, so to speak, on our consumer digital cameras of all formats, EDIUS does not "know" and can "handle" of. For a little before the old tape-based digital cameras, EDIUS can also be a 1394 line to control these machines, either DV or HDV camera or VCR, they can control play, pause, and back-recording operation.
To sum up some of the EDIUS features, we have a basic understanding of EDIUS. For the average home video, the post-editing is completely unnecessary to engage in the complex, as long as the raw material into the computer, the material removed in the useless part of the basic can be. And then advanced, you can cook the video title and subtitle recording date, you can also add the "background music", so that our own captured video more like a movie.

16:9 and 4:3 video of PK

Between 16:9 and 4:3 to say that the PK, it should say 16:9 is no problem winning. 4:3 because the first is an early film or video format standards, after years of use, is now entering the edge of elimination; second is 16:9 on the one hand is a relatively new standard, coupled with the frame is indeed more 4:3 is the original look and more comfortable to meet people's visual habits.
 4:3 still can not quickly eliminated because
As we say 16:9 ratio 4:3 in all aspects better, why 4:3 will not soon out of business? This also depends on two reasons: one is a lot of program source or 4:3 format, coupled with the current toll-free HD channels are very small, and the program source, and many other factors, the vast majority of 16:9 high-definition TV or watching 4:3 format program, the domestic point of view apart from a few large cities opened the cable HD channels, the vast majority of television stations in the traditional 4:3 format signal transmission; another On the one hand there are quite a number of TV subscribers, and there is no demand for the 16:9 format. Therefore, the 4:3 format programs in a given period will be the mainstream radio and television to use.
 Is accelerating out of the traditional 4:3 16:9
Although we can not say that the traditional 4:3 also soon "retired", but does not affect the rapid growth of 16:9. Currently we have access to the 16:9 format for playback and recording devices are high-definition flat-panel high-definition TV and home DV, especially in the past two years, high-definition flat-panel TVs and home DV spread very quickly, so that we can feel at any time 16: 9 existence, whether at the mall, friend's house; both 16:9 format flat-panel TV, or 16:9 (16:10) flat-panel computer monitors, are we on this 16:9 "aspect ratio" very familiar. In contrast to the traditional 4:3 being phased out of our vision, the old 4:3 CRT televisions and computer monitors, are quietly fading. Can be predicted a few years time, 4:3 aspect ratio devices will become history, or into the warehouse.
 16:9 and 4:3 which looks more comfortable then?
Look at the chart with this article, it is estimated we have the same feeling that a 16:9 aspect ratio to look more comfortable than 4:3, by contrast, can clearly feel the charm of 16:9. HD DV is currently shooting the picture is 16:9 SD format cameras generally have several options that you can use 4:3 or 16:9 can also choose to cover pieces of 16:9, 16:9 settings on the camera problem, we re-introduce the next article.

3D HD is here! Are we ready?

In 3D high-definition home soon after, long-awaited 3D professional HD cameras came out. 3D brought a lot of give you a sense of mystery, so that we can not be prepared to meet. "Avatar" in 3D surprise to us, but also to the digital camera manufacturers to bring business opportunities. Recently, the Panasonic AG-3DA1MC bright as a high-profile, let's look at what it can bring us.
 Panasonic AG-3DA1MC structure
Before we had an article, "Analysis of 3D Civil 3D camera TM750 features" described in Panasonic home 3D HD TM750, this home is a structure of high-definition 3D image sensor two lenses, we say that the AG-3DA1MC and home The TM750 other than the main song is with two image sensors, that is, two lenses to capture images were put into their 3MOS, and then processed through the signal recorded. This home model TM750 dual sensor camera image on a video put into a large difference, of course, the professional 3D HD must be better than home prices are much more expensive models.
 3MOSx2 or 6MOS
Previously in pure DV era, generally there is a single-CCD 3CCD or divided, or on the publicity of the body are to DV 3CCD to explain, now is not to say "6MOS" out? Because the number from the sensor to see if the Panasonic AG-3DA1MC in using a two-3MOS, add up to 6 MOS. Panasonic is the official website of "3MOS (support 1/4.1 inch progressive mode) x 2" to publicity. Modern technology is indeed the charm of endless, not to the camera and printer are also engaged in the same ink color from three to four, five, six color like. Besides this 3MOSx2 it, although 3MOSx2 is good, much stronger than the single MOSx2, but as a professional model, MOS size feels a little too small, only 1/4.1 inches, and Panasonic's current high end home machine type used is the same.
 Almost two machines to help with the line into 3D
Panasonic AG-3DA1MC by the structure of understanding, the simple fact to understand is the feeling that it is basically two small HD so a large shell, copy points should be interpreted inside the data processing system is relatively complicated. Therefore, the cost of this machine should not high, and two small high-definition hardware and main parts of the poor do not use a lot, but the price is definitely higher. Here I am reminded of a thing to write to, about two years ago, one of my friends in Germany began to study 3D, bundled with the DV method is two, so the 3D is not very complicated thing, in the currently no universal definition of the case, 3D, there should be some way to go, we have enough time to prepare.
