- Customizable subtitle styles and positions.
- Flexible duration per line of text.
How to Use the Text Overlay Captions API
To utilize the Text Overlay Captions feature, you can make a POST request to the /api/videos/add-text-overlay-captions endpoint. This API requires several parameters including the video URL and the text you want to overlay.
- Use the 'video_url' parameter to specify the video you want to enhance.
