Importance Of A Video Camera

Have you developed an interest in videography? Then you’ll also have to develop an affinity for video cameras. Video cameras are a videographer’s closest tool. If you want to improve in videography, you’ll have to master the use of a video camera. In this guide, we would be discussing the importance of a video camera. Read through, to find out the importance of video cameras.

Introduction To The Video camera

The development of portable video cameras capable of recording long sequences of high-quality video has been important for newsgathering, but video cameras are also very popular consumer items. In this section I shall be looking in more detail at elements of a video camera, using it as an example of an IT system which you are probably familiar with to some extent.

Even if you have not used one yourself you will have seen them being used or seen them in shops. (If you get the opportunity, you may like to have a look at a modern digital video camera in a high-street shop.)

‘Video camera’ is a contraction of ‘(video) camera and recorder’. There is an implication in this context that a video camera alone might not record (store) the image. Whereas a film camera always stores an image (on film), a video camera might only convert the image to an electrical signal for display remotely on a TV monitor.

For example, you can buy video cameras for domestic security which allow you to view outside your house by displaying the output of a camera on your television. If you connect one of these cameras to a video recorder you can record what you see, but the video camera does not itself contain storage.

A video camera is a combination of the two: the camera which converts the image to an electrical signal and a video recorder that records the electrical signal.

Types of a Video camera

First, decide on the type of high-definition video camera you want to buy. If you want better quality and more options, consider a full-sized model. If you need a smaller, more portable model, get an action cam, which is about half the size of a regular pocket video camera. Keep in mind, however, that today’s full-sized video cameras are smaller and more lightweight than previous models.

They fit easily in your hand and weigh as little as a half-pound yet still include at least a 10x optical zoom lens and other powerful possible features: Ultra High Definition, or 4K, resolution; 3D capability; GPS for geotagging; and built-in, or pico, projectors.

  • Full-Sized Video camera

Unlike analog video cameras of the past, digital models allow you to do a lot more with video than just play it back on a TV. You can edit and embellish with music using a computer, then play your productions on a computer, or on a DVD or Blu-ray player.

You can also email recordings or upload video clips to sites such as YouTube. Many video-editing software suites also let you combine video with digital stills, graphics, and text.

Most full-sized video cameras have at least a 10x optical zoom, although some have more (as much as 50x). At maximum zoom, most full-sized video cameras will produce jittery video because of a handshake or other factors. To compensate, most have an image stabilizer.

One feature found on many full-sized HD video cameras is an HDMI output, the best way to connect your video camera to an HDTV.

  • Action Cams

If you want a video camera that’s more compact than a full-sized model, you should consider an action cam, like one of GoPro’s Hero lines of a video camera. Such models are very small and lightweight, and they often have rugged bodies.

Action cams are designed for people who engage in outdoor sports and activities such as biking, surfing, and snowboarding, and want the ability to capture hands-free video. Because of their compact size, they may lack features such as a viewfinder or an LCD.

Although some have a waterproof exterior, most have a rugged and waterproof housing or removable case and mounting brackets for attaching the video camera to a helmet or another object.

Key Factors You Should Consider When Getting A Video Camera.

  • Sensor Size

As far as picture quality and exposure flexibility are concerned – and these are the main reasons people buy SLR cameras – the most important criteria are the size of the sensor and the size of each photosite on it.

The larger the photosite’s surface area, the more light it can capture and the more information it can record. The more information that goes to the camera’s image processor, the greater the dynamic (tonal) range in the resulting image – and the better the picture quality.

The differences are most obvious in shots taken in bright, contrasty conditions and in dim lighting. In bright lighting, the small sensors of compact digicams cannot record details in the brightest and darkest areas. The resulting pictures have blocked-up shadows and blown-out highlights and, when no detail is recorded, there is no way to tweak the image to improve the situation.

  • Megapixel Resolution

Although most advertising material and much of the media hype focuses on the number of megapixels the camera supports, the megapixel count is relatively unimportant when buying a digital SLR.

In theory, the number of megapixels in an image file should dictate the size to which it can be printed at ‘photo’ quality. However, you can produce excellent A3-sized prints from a 5- or 6-megapixel DSLR camera – provided the original shot was correctly exposed and edited.

Furthermore, an 8-megapixel sensor has only 30% more photosites than a 6-megapixel sensor. At the correct viewing distance for A3 prints, this difference will be negligible. Few photo enthusiasts are likely to want prints bigger than A3+ size, which is well within the capabilities of all current models.

  • Brand Loyalty

Photographers who already own a film SLR plus a suite of interchangeable lenses will be lured towards digital cameras from the same manufacturer. It makes both logical and financial sense to buy a body that will accept the lenses you have. However, it’s not necessarily the best option for the following reasons:

Most DSLR bodies change the effective focal length of a 35mm lens by a lens multiplier factor (LMF) of 1.5x to 2x. This means the 24mm lens that gave you a great wide-angle view will have the same angle of view as a 36mm lens on a 35mm camera. You gain a bit at the tele end; a 200mm lens becomes equivalent to a 300mm lens on a 1.5x LMF DSLR.

The 35mm lens is designed for imaging onto film, which has a different structure from an image sensor. It may not produce such good image quality on the DSLR body.

35mm lenses are often heavier and bulkier than digital lenses.

Olympus DSLR bodies cannot accept the lenses designed for Olympus film SLR cameras.

  • Lenses

Most entry-level DSLRs are sold with at least one medium-range zoom lens but an increasing number are being offered with two lenses. The additional lens is usually a tele zoom with a focal length range equivalent to about 70-200mm in 35mm format.

Twin lens kits represent great value so don’t be put off by comments about “cheap optics”. While the optics are usually housed in plastic (to minimize weight), the main compromise is lens speed (maximum aperture) rather than actual performance.

The plastic bodies may not be quite as tough as metal bodies, but they’re rugged enough for normal handling and a lot lighter to carry around and use.

Video camera Importance

Creating and editing videos has never been easier than with digital video cameras. A digital video camera provides a convenient way to create movies and put them on tape, DVD, or even the internet. As easy as it may seem it may still be prudent for you to understand some basics so that you can get the best quality video camera for your money.

There are some things to remember when shopping for a digital video camera. You should pay attention to a few key features of a digital video camera. The viewing screen is one of the most important and relevant factors of the entire device. Remember that you will use this screen not only for shooting your movies but for the convenient playback feature. You will want to be able to adequately view your playback.

Of utmost importance is the lens of any video camera. Most video cameras sold today feature at least a 10x zoom lens. This is adequate for most purposes. Often higher zoom levels are not able to maintain a quality video so they may not be useful.

All video cameras offer one of two types of image stabilization. They are electronic or optical. Image stabilization is incredibly important. The electronic stabilization counteracts images that seem to float on the CCD by using internal circuitry to interpret video after the image has been captured. The optical option uses the lens mechanism to compensate for external movements.

Sound is also an important consideration. The sound relies on the quality of the microphone on the video camera. Some video camera offer zoom microphones which enhance the voice quality of the subject being recorded. If the sound is important to your recordings consider a video camera that has a socket to plug in a remote microphone.

Do you need to film at night or in dark situations? Then you need to consider the night mode abilities of your video camera. Many video cameras offer the ability to film at night with the help of infrared or a special slow shutter mode that effectively utilizes ambient lighting. Some models provide both modes for capturing night videos.


Video cameras include a lot of features, such as titling, effects, and stills, but focus on the basics. Knowing the importance of video cameras will spur you to get one for yourself. In the review above, you’ll find the importance of video cameras.
