The Aspect Ratio option you have here is slightly different from the Aspect
Ratio you have used for the rest of your show. What you’re configuring
here is the pixel aspect ratio. The short explanation of this is that pixels will
be different shapes and sizes based on the aspect ratio that is selected. This
is independent of resolution.
The rule of thumb to follow here is that you want your Aspect Ratio to
match what you use in your show. If you make a 16:9 show, use 16:9 as the
Aspect Ratio for the video.
Another option here is called Square Pixels. Square Pixels doesn’t adjust
the shape of the pixels to a certain aspect ratio. Instead, it renders the video
on a 1:1 basis with the resolution.
As an example, consider this:
The resolution of a normal DVD video is 720 x 480. This is based
on the resolution and aspect ratio of 16:9. If you’re going to render
a DVD video at a ratio of 4:3, the pixels are adjusted in size so that
what is actually a 720 x 480 video doesn’t look distorted when
viewed on a 4:3 screen. If you were to use Square Pixels with this
video and watch it on a 4:3 screen the image would appear
squished and distorted because the Square Pixels keep the video
set to the size based solely on resolution – 3:2.
The best time to use Square Pixels as your Aspect Ratio is when you want
your video to match the chosen resolution exactly, regardless of what
device you use to display it. The option is most useful if you’re creating a
video using a non-standard resolution and intend to display it on a PC, only.
Encoding is much like the option you find for other output selections. The
Encoding quality determines how the video will look, by adjusting some
details about how the video gets encoded. In most all cases Normal
Quality will look great.
Desaturation and Anti-Flicker are the same options found during DVD
creation. For more details on these options, see Chapter 19.
Color Profile allows you to specify whether you want to use a color profile
with the video. For more details on this feature, see Chapter 24.
