Pro-guide to quality and resolution of video blog

You're scratching your head in thought about video resolution?

It's a bit confusing as there are a handful of technical aspects such as aspect ratio and pixels that you must first understand.

In this article will walk you through the nuances of video resolution in a simple words so that you can easily and efficiently wrap your mind about the idea.

As we dive into the manual, you'll find there's a common pattern: each video resolution will be a level higher than the one before.

What is the definition of resolution for video?

Resolution of the video screen, sometimes referred to as screen resolution, refers to the amount of pixels that are displayed across each frame.

Technically, this is the amount of pixels in a square meter, which is shared as 1080p x 1920 (width multiplied by height that is the number of pixels on the screen) also known as 1080p.

Remember: the size (1080p) is frequently utilized as the shorter version for the complete resolution.

What exactly is a pixel short?

Pixels or picture elements is the smallest image unit shown on a screen. Together, small dot- or square-shaped pixels make an image on a screen. When people talk about video resolution in reality, they're referring to the quantity of pixels.

In general, the more pixels on an image and the higher resolution, the more real the image looks. So a 1080p video resolution will always be superior to the 720p resolution because it has larger the pixels.

There are times when you'll be told that a resolution of a video is as 1080i. This 'i' is the model for "p," so when better and more powerful resolutions for screens appear there will be less of  the word 'i. But how do you define it?

In essence, the letters stand for:

'i'= interlaced

'p' = progressive

They also indicate the way the pixels are laid out or drawn on screen.

With interlaced resolution, the pixels are laid horizontally across the screen - clearly visible if you observe them up close on an old screen. In fact, as the pixels are painted horizontally onto the screen, first you will see the odd lines, then the even lines - you will see them flashing.

In order to overcome this issue, the pixels continually refreshed each second. This is a rate called"the refresh rate" (commonly sixty times every second).

Progressive screens are more advanced and have no problem with flicker. The pixels on a display are evenly colored in line order, meaning you can't see individual pixels even if you zoom in or magnify.

As the quality of videos is higher with advanced screens, the refresh rate terminology changed to suit the situation and the new frame rate as the title.

Frame rate refers to the rate at which the display screen shows each frame. It's typically 60 frames per second (fps).

What is an aspect ratio?

The resolution of video images is defined according to aspect ratio. It's an etymological term used to describe the width and height of an image.

It's usually indicated by two numbers separated by a colon (:). The image is X (say 16) units in width and up to y (say, 9) units high.

Video resolution vs video quality What's the distinction?

So is the quality of video and resolution the same? No.

However, beware of pulling your hair: the difference between them isn't that's too complicated. The resolution, like the one we discussed earlier, refers to the size of a pixel. In simple terms, it's how big an image appears on the display.

Quality of video is determined by the high-quality of the video or the quality of the pixels. High-quality pixels that store lots of details like contrast, color as well as shadows to mention just a just a few. These details give the picture good quality. It makes sense, doesn't it?

Standard definition: 240p vs 360p vs 480p

We'll now get into the weeds: what's standard definition or SD video quality?

Standard definition is a standard video resolution that's neither high nor upgraded. Simply put, it's not impressive. To understand the changes to HD 2, 2K and 4K, we need begin with the basics.Circling back: standard definition offers any of the three 3 resolutions: 240p as well as 360p and 480p resolution.

Image quality The general rule, keep in mind that the higher resolution there are, the sharper the quality of images. This is true for SD video resolution, as well. That means that 480p provides higher quality video than 360p, which consequently, provides better quality than 240p.

Is SD bad quality?

SD video quality is poor quality video. But it's suitable for viewers who are experiencing slow internet speeds as it streams more smoothly for them. It doesn't buffer.

High definition: 720p vs. 1080p

As time passed increasing pixel counts in order to satisfy the need for higher video quality. And, thus, came HD resolution video also known as high definition display.

It is available in two different qualities:

Image quality The fact that 1080p has around two million pixels, the image quality is more clear and smoother than HD 720p that has less than one million pixels. It's all about watching, naturally. For the casual observer, they might seem almost the same until they take a closer look. However, the difference can be significant to quality-conscious creators.

Note that 1080i and 1080p both come with HD resolution. The interlaced video resolution (1080i) is, however, isn't as smooth and crystal clear like 1080p, which is a progressive resolution (1080p).

HD vs SD video

Before moving further in the resolution chain and present the display with 2K resolution, we'll begin by comparing HD and SD video.

What's the resolution of 2K?

The situation gets a bit difficult when you exceed HD the resolution of your video. What exactly is that? Well, 2K isn't exactly 2K and certain cameras shoot just a little bit more than 2K, but not as high as 4K resolution.

Let's elaborate. 2K is 2048 x 1152 and has an aspect ratio of 1:1.77. No, not when you're thinking of it why 2K doesn't have the name 2048p. We've just started to roundup numbers. In essence, the name 2K from the fact that its pixels fit within the 2000 pixels range.

In the case of cameras that record a bit greater than 2K resolution they can capture 3840x 2160p, also referred to as 2160p (no round-ups here).

However, to avoid a lot of confusion, 2160p resolution is referred to as UHD which stands for ultra-high definition. As this resolution is 4 times HD and is also called 4K, but it's technically not 4K.

So what's 4K? It's higher than 2K resolution and UHD resolution. It also has a different aspect ratio too.

What's the resolution of 4K?

It is important to note that we are talking about width, not height or vertical pixel that has been the standard for sharing resolution. With 4K, the resolution is expressed in horizontal size or pixel width. This is the same for ultra HD.

For simplicity, let's bring everything together in a comparison chart:

Picture quality 4K is currently the norm for displays with high quality. It's also quickly becoming the industry standard as the Galaxy and iPhone gadgets are adopting the technology. The video quality is beyond amazing, naturally. Imagine what eight million pixels can do!

HDR vs SDR

There are two other players in this area: HDR and SDR which are both video and camera displays.

In short, HDR high-quality content has more contrast and brightness than SDR and is therefore better for visual enjoyment in comparison to SDR. Videos and images shot in HDR have a higher level of information (even when it's dark) as compared to the normal dynamic range.

The creators will appreciate this because HDR videos give more life to the story they tell, by capturing their story with vibrant colors and maximum detail.

Shooting Dolby Quality video in HD using iPhone 12 or later

Do you think you should shoot footage in breathtaking, cinema-quality HDR? This is the news we have for you: After creating videos in Dolby Vision on an iPhone 12 or later, editing the footage in Final Cut Pro (or ) or's platform, you'll be able to create a cinema-grade video made by you.

Dolby Vision is an HDR video technology utilized by the major Hollywood studios to deliver videos featuring highlights that are up to 40 times brighter, blacks that are 10x darker, and delivers viewers with creative intent in tact.

To turn it on, go to the phone's settings and choose Camera. Select the Record option then turn to HDR videos. That's all.

Once you've finished recording, anybody can upload their gorgeous newly recorded video to view and share - you won't want to keep this footage for your own!

Video resolution FAQs

    Are 4K as well as Ultra HD (UHD) the equivalent?    

4K and Ultra HD are often used interchangeably, but they aren't the same. 4K's pixel count is of 4096x2160p while UHD is 3840x2160p, which makes the video resolution different.                     Is FHD more effective than HD?    

To a viewer not paying close attention, FHD and HD can look the same. But FHD is far better than HD since it is packed with more than two million pixels, which offer a higher quality of visual as compared to HD, which has fewer than one million pixels.                     Which is the ideal quality video?    

The higher the number of pixels, the greater the video's resolution. This means 4K is better than 2K which is better than FHD. FHD, on the other hand, is superior to 720p HD and SD video.                     What are the types of quality video?    

There's standard definition (SD) as well as HD (HD) high definition (HD) quality. HD can be found in two versions: 1080p and 720p, with the HD being better than SD. Finally, there's 2K, ultra-high-definition (UHD), and 4K resolution.
