• $Outline1Contrast: Sets the opacity of the text’s outline 1 color.
• $Outline2Contrast: Sets the opacity of the text’s outline 2 color.
• $BackgroundContrast: Sets the opacity of the background color. This is usually set to
0, unless you are using a graphic that does not use white as the background color.
Position Commands
These commands control the subtitle’s position.
• $HorzAlign: Sets the subtitle’s horizontal alignment. You can enter left, center, or right.
• $VertAlign: Sets the subtitle’s vertical alignment. You can enter top, center, or bottom.
• $XOffset: Allows you to modify the subtitle’s horizontal position from where the
horizontal alignment placed it. The values you enter are in pixels, with positive values
moving the subtitle to the right and negative values moving it to the left.
• $YOffset: Allows you to modify the subtitle’s vertical position from where the vertical
alignment placed it. The values you enter are in pixels, with positive values moving the
subtitle up and negative values moving it down.
Display Commands
These commands control how a subtitle displays.
• $ForceDisplay: Forces the subtitle to display regardless of whether subtitles are turned
on by the DVD player. You can enter True (subtitles are forced to display) or False
(subtitle display is controlled by the DVD player).
• $FadeIn: Sets the fade time used to gradually dissolve the subtitles on. Enter a value
in frames.
• $FadeOut: Sets the fade time used to gradually dissolve the subtitles off. Enter a value
in frames.
Graphics File Command
Use this command if this subtitle file uses graphics files in addition to, or in place of, text
entries.
• $SetFilePathToken: Sets a token that you use on any subtitle entries that contain a
graphics filename instead of subtitle text. The entry must be such that it never appears
in normal text or filenames. The normal convention is to surround the text with dual
angle brackets, making it easier to locate within an STL file. For example, you could use
_Graphic_
. See Referencing Graphics Files in STL Subtitle Files for details.
