Depending on the project you're working on and also where the intended target is, for example, your project is viewable on DVD or its going to be on the web, this will dictate pretty much the project settings that you set. So, let's go ahead and create a brand new comp, I'm simply going to press command or control N and this opens up my compositions settings dialog box. As you can see here the first thing I can do is name my comp then I can look at some of the basic settings here. For example I can choose a preset, I can determine where its going to be so is it going to be on the web, will it be a web banner, will it be for television viewing. For example NTSC, will it be wide screen, will it be for European television and the PAL setting, will it be High Definition or will it be all out movie screen size. So I can choose my setting, I'll go ahead and just choose the DV wide screen for now and then I can- if I want to by the way, change some of the aspect ratios easily by simply sliding the hot text like so. And if I want to change it in my own custom settings even further I can deselect the lot aspect ratio, so I can make it a oblong or squash it and stretch it. I can also check the pixel aspect ratio, make it square pixels, make it oblong pixels and I can change the frame rate. And by the way speaking of pixel aspect ratio, let me just show you something real fast here. If I choose square pixels this is going to be good for viewing on a computer monitor. For example if I choose web video or I choose anything that's going to have to do with viewing on the web I'm going to get square pixels. If I choose a format, for example TV, I'm going to get oblong pixels, so the aspect ratio will have a pixel that's not square for television viewing and square for web viewing, so that's very important to remember as well. When you're working on the computer and people are going to play a video game or their going to watch it on the computer screen itself you want to deal with square pixels. When you're dealing with NTSC or anything else like that you're going to have a longer pixel or a square pixel it depends, it changes based on what you're working on in your aspect ratio. We can also change the resolution from full, half, third and quarter or choose custom and we can also change the start timecode and the duration and we can also go to the advance setting if necessary to deal with plug ins and that kind of thing, motion blur, I'm going to go ahead and cancel that for now. Now what if you're already in a composition and let's say for example you forgot what you're settings are, not a problem, just go to the composition menu, choose composition settings and now you can see what the composition is. For example I can see the name; I can see the settings, the frame rate and so on. So, you can choose to create your own custom settings or you can simply use the settings that are found in the presets to create your comps. And once again you can always check your comp settings by going to the composition menu and choosing composition settings.
