Properties

Alignment

If no explicit xPosition or yPosition is provided, setting alignment to centered places the captions at the bottom center of the output. Similarly, setting a left alignment aligns captions to the bottom left of the output. If x and y positions are specified in conjunction with the alignment parameter, the font is justified (either left or centered) relative to those coordinates. Selecting "smart" justification left-justifies live subtitles and center-justifies pre-recorded subtitles. All burn-in and DVB-Sub font settings must match.

Required: No

Type: String

Update requires: No interruption

BackgroundColor

Specifies the color of the rectangle behind the captions. All burn-in and DVB-Sub font settings must match.

Required: No

Type: String

Update requires: No interruption

BackgroundOpacity

Specifies the opacity of the background rectangle. 255 is opaque; 0 is transparent. Keeping this parameter blank is equivalent to setting it to 0 (transparent). All burn-in and DVB-Sub font settings must match.

Required: No

Type: Integer

Update requires: No interruption

Font

The external font file that is used for captions burn-in. The file extension must be .ttf or .tte. Although you can select output fonts for many different types of input captions, embedded, STL, and Teletext sources use a strict grid system. Using external fonts with these captions sources could cause an unexpected display of proportional fonts. All burn-in and DVB-Sub font settings must match.

Required: No

Type: InputLocation

Update requires: No interruption

FontColor

Specifies the color of the burned-in captions. This option is not valid for source captions that are STL, 608/embedded, or Teletext. These source settings are already pre-defined by the captions stream. All burn-in and DVB-Sub font settings must match.

Required: No

Type: String

Update requires: No interruption

FontOpacity

Specifies the opacity of the burned-in captions. 255 is opaque; 0 is transparent. All burn-in and DVB-Sub font settings must match.

Required: No

Type: Integer

Update requires: No interruption

FontResolution

The font resolution in DPI (dots per inch). The default is 96 dpi. All burn-in and DVB-Sub font settings must match.

Required: No

Type: Integer

Update requires: No interruption

FontSize

When set to auto, fontSize scales depending on the size of the output. Providing a positive integer specifies the exact font size in points. All burn-in and DVB-Sub font settings must match.

Required: No

Type: String

Update requires: No interruption

OutlineColor

Specifies the font outline color. This option is not valid for source captions that are either 608/embedded or Teletext. These source settings are already pre-defined by the captions stream. All burn-in and DVB-Sub font settings must match.

Required: No

Type: String

Update requires: No interruption

OutlineSize

Specifies font outline size in pixels. This option is not valid for source captions that are either 608/embedded or Teletext. These source settings are already pre-defined by the captions stream. All burn-in and DVB-Sub font settings must match.

Required: No

Type: Integer

Update requires: No interruption

ShadowColor

Specifies the color of the shadow cast by the captions. All burn-in and DVB-Sub font settings must match.

Required: No

Type: String

Update requires: No interruption

ShadowOpacity

Specifies the opacity of the shadow. 255 is opaque; 0 is transparent. Keeping this parameter blank is equivalent to setting it to 0 (transparent). All burn-in and DVB-Sub font settings must match.

Required: No

Type: Integer

Update requires: No interruption

ShadowXOffset

Specifies the horizontal offset of the shadow that is relative to the captions in pixels. A value of -2 would result in a shadow offset 2 pixels to the left. All burn-in and DVB-Sub font settings must match.

Required: No

Type: Integer

Update requires: No interruption

ShadowYOffset

Specifies the vertical offset of the shadow that is relative to the captions in pixels. A value of -2 would result in a shadow offset 2 pixels above the text. All burn-in and DVB-Sub font settings must match.

Required: No

Type: Integer

Update requires: No interruption

TeletextGridControl

Controls whether a fixed grid size is used to generate the output subtitles bitmap. This applies only to Teletext inputs and DVB-Sub/Burn-in outputs.

Required: No

Type: String

Update requires: No interruption

XPosition

Specifies the horizontal position of the captions relative to the left side of the output in pixels. A value of 10 would result in the captions starting 10 pixels from the left of the output. If no explicit xPosition is provided, the horizontal captions position is determined by the alignment parameter. All burn-in and DVB-Sub font settings must match.

Required: No

Type: Integer

Update requires: No interruption

YPosition

Specifies the vertical position of the captions relative to the top of the output in pixels. A value of 10 would result in the captions starting 10 pixels from the top of the output. If no explicit yPosition is provided, the captions are positioned towards the bottom of the output. All burn-in and DVB-Sub font settings must match.

Required: No

Type: Integer
