The caption settings dialog is an on-screen control panel that appears as a modal window during video playback. It lets viewers adjust how captions and subtitles look while they watch a video. From this dialog, users can change text color, background color, window color, transparency levels, font size, edge style, and font family. The goal is to make captions easier to read and more comfortable for different viewing preferences and accessibility needs.

Viewers can customize several aspects of how captions and subtitles appear: - **Text color:** White, Black, Red, Green, Blue, Yellow, Magenta, or Cyan - **Text transparency:** Opaque or Semi-Transparent - **Background color:** Black, White, Red, Green, Blue, Yellow, Magenta, or Cyan - **Background transparency:** Opaque, Semi-Transparent, or Transparent - **Window color:** Black, White, Red, Green, Blue, Yellow, Magenta, or Cyan - **Window transparency:** Transparent, Semi-Transparent, or Opaque - **Font size:** 50, 75, 100, 125, 150, 175, 200, 300, or 400 - **Text edge style:** None, Raised, Depressed, Uniform, or Dropshadow - **Font family:** Proportional Sans-Serif, Monospace Sans-Serif, Proportional Serif, Monospace Serif, Casual, Script, or Small Caps These options help users reimagine how captions fit their screen, lighting conditions, and personal accessibility requirements.

Users have several controls available directly in the video player: - **Playback controls:** Start, pause, and resume the video, and switch to fullscreen mode. - **Playback rate:** Adjust how fast or slow the video plays (for example, speeding up to move through content faster or slowing down to review details). - **Audio track selection:** Choose from available audio tracks, which can support different languages or audio descriptions. - **Captions and subtitles:** Turn descriptions and subtitles on or off, and open the captions settings dialog to fine-tune how they appear. All of these controls are designed to help viewers reshape the viewing experience so it matches their pace, language needs, and accessibility preferences.
