One of the things that tends to be confusing for new Premiere users, it actually tends to be confusing for a lot of people, is the standards for High Definition video or in other words HD video. So let's go over to Project panel again, and create a new sequence and look at what are the HD standards. Now if we close up the Digital SLR, we have basically the standards in a sense. The 480p is kind of like the standard for regular video and actually it is 480i. So if we click DV-NTSC, open that up, click on Standard 48kHz, we can see that there are some standards here.
29.97 frames/second, and it is 720 pixels wide by 480 pixels tall, in order words horizontal and vertical, what the h and v stand for. When we talk about size as far as video goes, we often just use the vertical height in pixels or in other words in lines. So for a regular standard definition video, which is 720x480, this is referred to often as 480i. It's referred to as i, because it refers to interlaced fields and what that is, they make little horizontal bands, 480 horizontal bands, from the footage and then they interlace them with the next frame.
So this is what they refer to here, Fields. Lower Field First that means this is interlaced footage. But as we go up to higher definition, we have 480p. This is not a High Definition standard. This is referred to as ED or Enhanced Definition. This is not very common. Now to add to the confusion, because when there was Standard Definition, there is basically just SD and that's it. It eventually then came out with widescreen but that was the same pixel dimensions. It's just a different pixel aspect ratio and that's really only difference there. But the pixel dimensions were the same.
HD has kind of made things a little confusing, because there are so many formats. So I'm going to close that Digital SLR and actually all these other preset folders as well, and open up AVCHD and here in we find the standard HD formats. We have 720p. This is 1280x720 with a progressive frame rate. Then we have 1080i, which as you can see here is broken up into 25 frames per second, 50 frames per second for PAL, and 30 and 60 frames/second for NTSC. 1080i is 1440x1080, but it has interlaced frames.
Really true HD is 1920x1080 progressive frames. Again, progressive is when those frames are not interlaced and you see the entire frame as a whole. So again, the term HD Standard is kind a misnomer, because there are multiple standards for HD. So it can be 1280x720 progressive frames and that is HD. It can be 1080i, and that is HD. It can be 1080p, and that can be HD as well. When they talk about true HD or full HD, that's usually 1920x1080 with progressive frames.
