In the US, only interlaced (480i) is available and tends to have a square-ish aspect ratio, ie, 4:3. 4K files will require much more storage and bandwidth.Īs its name suggests, the quality of SD resolution (640 X 480) refers to the standard for most of distribution/reproduction channels and screens.The resolution refers to a pixel height of 480 in a single image.įor broadcasters, it’s the starting point. For example, 1 hour of HD video on average will require 8GB of storage. The more detailed the video, the larger and heavier the file will be and the more bandwidth they will consume. The amount of space your video files occupy will determine how much bandwidth they will consume. So, it’s clear that- the more horizontal lines of resolution used to make each frame of video, the more detailed the picture will appear making progressive scanning much better than interlacing. Progressive method delivers a better resolution in general, as the motion appears more fluid. However, your eyes while perceiving the full image in motion, start filling in the gaps making a complete picture out of it.Īs opposed to interlacing, Progressive scanning is a technique of displaying or transmitting moving images in which all the lines of each frame are drawn in sequence, without alteration. What happens in interlacing is that your eyes in reality gauge every alternative line of a picture frame. Interlacing video is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. These letters refer to the method in which the video has been recorded where ‘i’ stands for ‘interlaced’ and ‘p’ stands for ‘progressive’ or ‘non-interlaced’. We often come across the letters ‘i’ and ‘p’ after the numbers 720, 1080 and so on. The aspect ratio tends to be wider than taller for sharper definition. For example, a 16:9 aspect ratio means that for every 16 inches wide, the image must be 9 inches tall. For example when we talk about 1080p, we mean that the quantity of pixels displayed by height is 1080p while the quantity of pixels displayed by width is 1920p (1920p X 1080p)Īspect ratio is the proportional relation between the width and height of an image. Generally, when we define a video resolution, we refer to the height of the pixels. For example, when you see “1920p x 1080p” in a video description, you can know it’s saying the image is 1920 pixels wide, and 1080 pixels tall. When you hear labels of these sort, remember that they are pixels displayed in the video, width by height. Ideally, the more pixels the image has, the better is the clarity of the image.Ĥ80p | 720p | 1080p – What’s with the numbers? Simply put, video resolution is the number of pixels that make up a single frame in your video and pixels are the smallest units that make up a picture in a video frame. In the next 5 minutes you are going to get a detailed overview of streaming video resolutions i.e. So, without further ado, lets jump right into the basics of video resolution. As a content creator, you should start caring about video resolutions if you want your on-demand video or live streams to reach a wider audience. Resolution greatly influences the viewing experience, particularly when the video is played on large screens. Alongside frame rate, it’s the top-most feature to keep in mind to determine video quality.Īlthough various factors affect the quality of video streaming like frame rate, compression processes etc, video resolution is the most basic and most dominating parameter because it reflects the detail of the frames of the video. One of the key aspects of delivering a good quality video is understanding and determining the correct video resolution of an on-demand video or live stream. The dynamics of video delivery and consumption are changing rapidly in today’s world and keeping pace with the constantly evolving video streaming standards is becoming a challenging job not for just content owners but broadcasting and streaming distributors as well.
