Figure 4-17: Crawl Logo Configuration Settings
4.13.9.1. Setting the Crawl Logo Horizontal Position
This option is used to set the horizontal position for vertical crawls. The position is referenced to the
left edge of the logo. The range of values depends on video standard in use.
4.13.9.2. Setting the Crawl Logo Vertical Position
This option is used to set the vertical position for the horizontal crawls. The position is referenced to
the top edge of the logo. The range of values depends on video standard in use.
4.13.9.3. Setting the Crawl Logo Transparency (Gain)
This option is used to adjust the opacity (the inverse of transparency) of the logo as a percentage of
the original opacity when the logo was created. When the
Gain
value is set at its default value of 100
the logo will be displayed at its original opacity.
For example, if the logo is created at 10% opaque, adjusting the
Gain
value to 200 will render the logo
as 20% opaque. If the logo is created at 50% opaque, adjusting the
Gain
value to 200 will render the
logo as 100% opaque.
Gain
values resulting in opacity levels above 100% are ignored.
