Coding

Specifies the character set used for the subtitle text.

Primary color

Specifies the primary color of the subtitle.

The primary color is the main color used to display subtitle text.
It determines the appearance of the text and significantly influences its readability and visual impact. When rendering subtitles, the primary color is applied directly to the text—usually white, yellow, or another high-contrast color to ensure good visibility against different backgrounds.

Secondary color

Specifies the secondary color of the subtitle text.

The secondary color is an additional color used in combination with the primary color when displaying subtitles.
It is typically used in special applications such as karaoke or special effects.

Outline color

Specifies the outline color of the subtitle text.

The outline color refers to the color of the border (contour) that surrounds the subtitle text.
It improves the readability of subtitles, especially against high-contrast or busy backgrounds.
When rendering subtitles, the outline is displayed along with the text, making the subtitle more clearly distinguishable from the video content.
A well-chosen outline color (e.g., black or white) ensures better visibility on all screen types.
