Why Do Video Cameras Have Such Low Megapixels?


Isn’t it surprising that video cameras have low megapixels? That begs many questions. Why is that the case? Do more pixels mean better video quality? Let’s find out.

So, why do video cameras have such low megapixels? In reality, low megapixels cameras offer better quality, low image noise, fast processing, better sensors, more significant viewing distance, and many cheaper fixes. To bust some myths about higher megapixel vs. low megapixel cameras, read on.

Before highlighting why video cameras have low megapixels, it is interesting to note that cameras with high megapixels keep bombarding the market now and then. Releases of phones with up to 64 megapixels cameras or more have become the order of the day. 

That being said, strangely, most video cameras have low megapixels. Therefore, designers make video cameras with low megapixels intentionally and not for lack of higher alternatives. 

So what is the logic behind that? Is it merely a mentality that more megapixels translate to excellent video quality? Does lowering the megapixels for video cameras affect the images? Decoding the answers is the perfect way of ensuring that you get quality and value for your money. 

This piece will enlighten you by answering all the questions and much more. Read on!

So, why do video cameras have such low megapixels?

Given how most camera marketers make everyone believe that the more the megapixels, the better the camera has made people think that it is the truth. However, in some cases, it is true, but that can also be wrong under other circumstances. Let’s check them out.

Quality

It is essential to understand some logic. Full HD means 1920 x 1080 pixels. That sums up to 2.07 million pixels. If you convert that to megapixels, that’s about 2 megapixels. If you decide to add more pixels, that will translate to the capture of a lot more information. Nevertheless, the information will be of a relatively low quality.

Processing

When dealing with more than 2 megapixels and an HD screen, the data that you capture will need processing. In the process, the quality of the picture might degrade. However, when using 2 megapixels, which are quite low, that will not be necessary. 

Since the recording and replaying will be at the same proportion, it will need no or little processing. As a result of that, expect several things. They include improvement of not only the dynamic range but also in low-light sensitivity. Equally important, it is in a position to capture a lot of gradations of both light and dark.

Cheaper fixers

Instead of buying an expensive video camera for a large amount of money, you can use one with low megapixels with it. If you combine it with some accessories, the result will even be more significant than before. 

When capturing the likes of wildlife imagery, you might need to crop it to get closer to what you want to achieve. That may also be necessary when posting your images. That demands that you go for a high-resolution camera. That will cost you a lot. Instead of that, it would be simpler to get a teleconverter instead. It will ensure that you shoot the object to fill the frame without having to break the bank.

If you need to shoot a vast landscape, a camera with many megapixels comes in handy. However, you may not be in a position to afford it. Fortunately, with a cheap video camera with low megapixels, all you need is to shoot a panorama and get the same result. 

The feature means several things. It is all about taking advantage of noise reduction. That will see to it that you trade some image details. If that doesn’t happen, the flexibility of the image is at its best, which facilitates easy post-processing. The feature ensures that you shoot about three images which overlap by 50 percent. Consequently, you double the pixels for the final image.

Viewing distance 

You will be surprised to learn that a video camera with low megapixels is the best if you will print the images after capturing them. That’s because the viewer doesn’t have to maintain a substantial distance to appreciate the picture. No wonder some images appear sharper when large and far than when small and close. A good example is billboards.

Sensor

Despite having low megapixels, most video cameras have an excellent sensor. Photo means light, and it is impossible to have a photograph without it. Since it is the sensor that captures light, it is an important feature. It plays a huge role when it comes to photography and videography. 

When the light enters the camera through the lens, it passes through the sensor. That’s where the collection of the information, as well as its translation into an electronic signal, takes place. After that, the image takes over and starts the creation, followed by the fine-tuning of the picture. It eliminates issues such as noise too.

That said, the sensor is dispensable. The size of the sensor determines that of the pixels, and the two are directly proportional. The pixels, in return, affects the light that the photographer will collect. If the light is a lot, the quality of the image will be excellent. 

So, a wise photographer and videographer will consider a video camera with low megapixels but a big sensor. You can’t get those big sensors on your cellphones. It fails the very purpose of microchip sensors that do little to capture images with higher megapixels.

Noise

Besides, it is good to keep in mind that if you want to make the image noise as low as possible, you need to go for a video camera with low megapixels. Though the higher megapixels capture more information, they have lower sensitivity due to lower light information on each pixel. Hence the images will be noisy. To reduce the noise, you need signal correction, which induces heavy processing, thus defeating the purpose of better images at higher megapixels.

Do more megapixels mean better video quality?

To some extent, more megapixels could mean better video quality. So, the more the megapixel on the sensor, the better the picture. That’s because the camera will capture a lot of details. 

A 6 MP sensor is better than a 4 MP one. Compared to a 3 MP and 1.5 MP, it is even better. Nevertheless, that may not mean a lot of you intend to view them from a smartphone, computer, or HDTV. Despite that, it means a lot as far as one wants to print the images.

It is not always the case. That is especially if your camera has a small sensor. Here is an explanation. 

As mentioned earlier, light is essential as far as videography and photography areconcerned. In addition to that, the more the light, the better the image.However, the more the pixels on your small sensor, the less the light thatreaches the image processor. Consequently, the color and brightness arecompromised. The situation is even worse if the lighting is pathetic or insteadleaves a lot to be desired.

So now, you have an idea of why video cameras have such low megapixels. To some extent, it ensures that you get great results without having to dig too deep into your pocket. One with many megapixels may not be what you need to capture excellent footage. 

If you want a camera to use for your posts or to print afterward, don’t even consider going for a camera with a vast number of megapixels. If zooming and cropping will be necessary, one with many megapixels is essential. However, you can as well use the fixers discussed in this article.

Never forget that megapixels alone don’t determine the quality of the videos and pictures. There are other determining factors, such as flash focus, sensor, and lens. Therefore, do not let high megapixels blind you into buying something that will give you pathetic results. 

Final Words

Never shy away from purchasing video cameras with low megapixels because that could precisely be the reason why they produce more magnificent videos and pictures. 

The bottom line is, there exist many reasons that justify why video cameras have such low megapixels. For a non-techie commoner like me, I guess it is enough to make the decision.
