What Is the Difference Between 1080p and 1080i?

Summary: We will be distinguish the 1080p and 1080i in this article in the aspect of resolution, frames, fields, frequencies. And then give the solution on how to edit both 1080p and 1080i video in FCP X/7/6.

Q: I have seen many times resolution of 1080p and I know that mean 1080 pixels but sometime I also seen option on the HDTV is 1080i. So I want to know the exact difference between them and is 1080i video quality available for the laptop too?

I have Googled 1080i some times rather than 1080p. Is there any difference between them? Or they represent the same?


The question is specifically: What is the difference between 1080p and 1080i? so I will start by outlining the main similarities and differences, I’ll add some tips on how to choose the best format and then I will proceed to explain the problems that I found here.

Resolution

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 × 1080 pixels (2.1 megapixels). It is not true that 1080i has a lower vertical resolution than 1080p.

Frames vs. Fields

1080p is a frame-based or progressive-scan video where you are dealing with frames. You have frame rate and it is expressed in frames per second.

1080i is a field-based or interlaced or interleaved video where you are dealing with fields. You have field rate and it is expressed in fields per second.

A field contains half of the lines of the frame, either even lines or odd lines, and if one field is composed of even lines, then the next one will be composed of odd lines and so on.

Frequencies

1080p has a frame rate of 25 frames per second for TV in PAL countries, 30/1.001 frames per second for TV in NTSC countries and 24 frames per second for cinematography.

1080i has a field rate of 50 fields per second for TV in PAL countries and 60/1.001 fields per second in NTSC countries.

How to edit both 1080p and 1080i video in FCP X/7/6 smoothly?

For whatever video resolution, frames, fields, frequencies, we got the ultimate usage is make it more vivid or more moving for playback. We always want to add some video effects in the video, though FCP, Avid, Premiere or other NLEs you familiar with. Any editor have it’s natively format for editing, such as Apple Prores for FCP, MEEG-2 for Premiere, DNxHD for Avid. Here we choose FCP as example.

In order to edit 1080p and 1080i video in Fcp smoothly. First you should check out the format your 1080p or 1080i video is. In generally speaking the video may not codec in Apple Prores, you should convert the video format into Apple ProRes for FCP. Second, the video resolution, frames, fields, frequencies of 1080i are not suitable for editing in FCP. You’d better change it into 1080p and make it editable. Here we recommend you a professional video tool for you--Pavtube HD Video Converter for Mac(read the review). With it you can change the 1080p or 1080i video into Apple ProRes codec and make it can be edited in FCP smoothly. 

What's more, the program also boasts with some beneficial functions to enhance you video viewing experience on portable devices. For example, you can trim the video to cut unwanted clips from the video, adjust the output video aspect ratio to make it suitable for your output device, add external subtitles to YouTube movies to understand it better.
