Understanding the Basics of Video Resolution
Before we dive into the specifics of 720p and 1080i, it’s essential to understand the basics of video resolution. Video resolution refers to the number of pixels that make up an image on a screen. The more pixels, the higher the resolution, and the clearer the image. There are two primary types of video resolution: progressive scan and interlaced scan.
Progressive Scan vs. Interlaced Scan
Progressive scan, denoted by the ‘p’ in 720p, displays the entire image at once, with each line of pixels being drawn in sequence. This results in a smoother, more detailed image. On the other hand, interlaced scan, denoted by the ‘i’ in 1080i, displays the image in two fields: one field contains the odd-numbered lines, and the other field contains the even-numbered lines. These fields are then combined to create the final image. Interlaced scan can sometimes produce a less smooth image, especially in scenes with fast motion.
Resolution and Aspect Ratio
The resolution of a video is often expressed in terms of the number of horizontal lines of pixels. For example, 720p has 720 lines of pixels, while 1080i has 1080 lines of pixels. The aspect ratio, which is the ratio of the width to the height of the image, also plays a crucial role in determining the overall quality of the video. A wider aspect ratio can provide a more immersive experience, but it may also lead to a lower pixel density.
Detailed Comparison of 720p and 1080i
Now that we have a basic understanding of video resolution, let’s take a closer look at 720p and 1080i. Both resolutions are considered high-definition, but they have some key differences.

720p has a resolution of 1280×720 pixels, resulting in a total of 921,600 pixels. On the other hand, 1080i has a resolution of 1920×1080 pixels, but because it’s interlaced, the effective resolution is lower. The pixel density of 720p is generally higher than that of 1080i, especially when it comes to fast-moving scenes. This means that 720p can produce a clearer and more detailed image, especially in scenes with a lot of motion.
Motion and Refresh Rate
The refresh rate, which is the number of times the image is updated per second, also plays a crucial role in determining the overall quality of the video. 720p typically has a higher refresh rate than 1080i, which can result in a smoother and more responsive image. This is especially important for gamers and viewers who watch a lot of fast-paced content.
