Join Chris Meyer for an in-depth discussion in this video Creating a 4:3 center-cut version, part of After Effects Apprentice 15: Creating a Sports Opening Title.
- [Instructor] What if a client also says they want a 4 by 3 center cut of your wide screen version? Let me show you how to do that. First thing I'm going to do is add another output module, choose a template to begin with, like Quicktime DV NTSC. Click on it and let's edit the settings. The first thing I need to do is to resize my square pixel composition resize my square pixel composition to provide the non-square pixels required by DV or D1 NTSC. to provide the non-square pixels required by DV or D1 NTSC.
I'm going to turn off the lock aspect ratio and the proper pixel aspect ratio for D1 or DVNTSC and the proper pixel aspect ratio for D1 or DVNTSC is the scale to eleven tenths. So I'm going to bring out my calculator here. Take 8 and 72 pixels times 11 Take 8 and 72 pixels times 11 divided by 10 equals 959.2. divided by 10 equals 959.2. Best to round it up to an even number so later on you can trim things equally off the left and right sides. Enter 960 pixels here. Enter 960 pixels here.
That's going to give me an 11 to 10 aspect ratio. Next I need to crop this down to the requirement of the DV output. Now to get 486 lines down to 480, you already know, crop 4 from the top, 2 from the bottom. For center cut we want to chop off large portions of the left and right sides of the screen and keep just the center portion of it getting down to our 4 by 3 aspect ratio. So we need to take 960 pixels So we need to take 960 pixels minus our 720 target.
minus our 720 target. Divided by 2 for the left and right sides. We need to take 120 pixels off of each side. 120 off the left. 120 off the right. We now have a 720 by 40 output and you notice a little warning down here that we had a settings mismatch went away cause now we've hit our target of DV NTC output. went away cause now we've hit our target of DV NTC output. So again to review, first we had to take into account non-square pixels, make it eleventh tenths wide.
Second, we had to crop to get rid of the excess of the wide screen and get down to a four by three center code. Okay.
