Master Prores 1080p Or 1080i: Which One Should You Choose?
If you are working with high-definition video, you may have encountered the terms 1080p and 1080i. These are two different formats of video resolution that have different advantages and disadvantages. In this article, we will explain what they mean, how they differ, and which one is better for your project.
What is 1080p and 1080i?
Both 1080p and 1080i have 1080 horizontal lines of vertical resolution, which with a widescreen aspect ratio of 16:9 results in a resolution of 1920 x 1080 pixels (2.1 megapixels). However, they differ in how they display the image on the screen.
1080p is short for 1080 progressive scan, which means that the image is displayed by scanning every row of pixels progressively, refreshing every row on the screen 60 times per second. This produces a smooth and sharp image, especially for fast-moving scenes.
1080i is short for 1080 interlaced scan, which means that the image is displayed by scanning odd and even pixel rows in an alternating fashion. The odd rows are scanned first, then the even rows, creating two fields that make up one frame. Each field flashes 30 times per second, so the effective frame rate is still 60 frames per second. However, this can cause some flickering and blurring effects, especially for fast-moving scenes.
What are the pros and cons of 1080p and 1080i?
The main advantage of 1080p over 1080i is that it offers superior image quality, as it avoids the interlacing artifacts that can occur with 1080i. This is why 1080p is often referred to as "true" or "full" HD. 1080p is also more compatible with modern devices and displays that use progressive scan technology.
The main disadvantage of 1080p over 1080i is that it requires more bandwidth and storage space, as it has twice the amount of data per frame than 1080i. This can be a problem for broadcasting and streaming services that have limited bandwidth or data caps. It can also be a problem for editing and transcoding software that may not support 1080p or may take longer to process it.
The main advantage of 1080i over 1080p is that it requires less bandwidth and storage space, as it has half the amount of data per frame than 1080p. This can be a benefit for broadcasting and streaming services that have limited bandwidth or data caps. It can also be a benefit for editing and transcoding software that may not support 1080p or may process it faster.
The main disadvantage of 1080i over 1080p is that it offers inferior image quality, as it can cause interlacing artifacts that can degrade the image. This can be a problem for fast-moving scenes or scenes with fine details that can become blurred or jagged. It can also be a problem for modern devices and displays that use progressive scan technology and may not display interlaced video properly.
Which one should you choose?
The choice between 1080p and 1080i depends on several factors, such as your source material, your output device, your intended audience, and your personal preference.
If your source material is already in 1080p format, such as a Blu-ray disc or a digital camera recording, then you should stick with 1080p for the best quality. If your source material is already in 1080i format, such as a broadcast TV signal or a DVD recording, then you should stick with 1080i to avoid unnecessary conversion.
If your output device is capable of displaying 1080p video, such as a modern HDTV or a computer monitor, then you should choose 1080p for the best quality. If your output device is only capable of displaying 1080i video, such as an older HDTV or a projector
