Quran Caption provides many settings to customize the rendering of your video. To access these settings, click on the `Video Editor` tab. Then, in the left panel, click on the `Subtitles Settings` tab.

In this section, you can customize the appearance of your subtitles. Options include adjusting the font, size, color, background, and more. You can also change the position of the subtitles on the screen.

The Global menu item allows you to adjust the padding of the subtitles, the background image/color of the video, and a custom creator text that will be displayed at the bottom of the video (this can include the reciter's name, the surah name, or your @ on social media). There are additional options for customizing the rendering of the video, so feel free to explore them.

You can also individually customize the appearance of each translation by selecting the desired translation from the dropdown list.
