4.2.2. Choosing the Raster limits for the Mask Aspect Ratio and Size Calculation
Mask apert =
prod
This menu item sets how the aspect ratio and size calculations for the mask and grid objects are
calculated. In either setting, the mask and grid objects can be positioned all the way out to the production
aperture. When you choose one of the automatic aspect ratios for the mask object, its initial size and
position will be calculated with respect to the mask aperture setting. See section 4.5.2 for information on
selecting the mask aspect ratio.
Select prod when you want to use the production aperture as the reference for the mask and grid object
aspect ratio and size.
Select clean when you want to use the clean aperture as the reference for the mask and grid object
aspect ratio and size.
Select analg when you want to use the nominal analog blanking as the reference for the mask and grid
object aspect ratio and size.
4.2.3. Choosing the Raster limits for the Box Size Calculation
Box apert =
prod
This menu item sets how the size percentage calculations for the box object are calculated. In either
setting, the box object perimeter can be positioned all the way out to the production aperture.
Select prod when you want to use the production aperture as the reference for the box object size
calculation.
Select clean when you want to use the clean aperture as the reference for the box object size calculation.
Select analg when you want to use the nominal analog blanking as the reference for box object size
calculation.
4.2.4. Setting the Pixel Aspect Ratio (9590 only)
Pix =
This menu item sets the pixel aspect ratio relative to that of the input video.
Select analog 4:3 when you are working with normal aspect ratio video and you want to define the 4:3
aspect ratio according to the nominal analog blanking.
Select analog 16:9 when the input video has been compressed from a 16:9 format to a 4:3 format and
you want to define the 16:9 aspect ratio according to the nominal analog blanking. Objects will be drawn
in their compressed state, so that they will appear normal when the video is expanded again.
