In the digital age, video content is key for engaging audiences, especially on social media platforms. Adding text overlay captions can make your videos more accessible and impactful. With FFMPEGAPI.net, a hosted REST API for FFmpeg-powered video processing, developers can easily integrate text overlay functionality into their applications without the hassle of server setup or infrastructure management. This article will walk you through how to use the Text Overlay Captions endpoint to enhance your video content.

What is the Text Overlay Captions API?

The Text Overlay Captions API allows developers to render text as timed overlays on videos. This feature is particularly useful for social media videos where captions can boost viewer engagement and comprehension.

  • Add multiple lines of text to your videos.
  • Customize the appearance with various subtitle styles.
  • Choose the position of the text overlay easily.

How to Use the Text Overlay Captions Endpoint

To use the Text Overlay Captions API, you need to make a POST request to the endpoint: /api/videos/add-text-overlay-captions. The API accepts several parameters that allow you to customize how the text overlays appear in your video.

  • video_url (required): The URL of the video you want to process.
  • text (required): The lines of text you want to overlay, separated by newlines.
  • subtitle_style (optional): Choose from styles like plain-white or yellow-bg.
  • aspect_ratio (optional): Set your desired aspect ratio, such as 16:9 or 9:16.
  • position (optional): Specify where the text should appear - top, center, or bottom.
  • duration_per_line (optional): Control how long each line of text is displayed.
import requests

url = 'https://ffmpegapi.net/api/videos/add-text-overlay-captions'
data = {
    'video_url': 'https://example.com/video.mp4',
    'text': 'First line\nSecond line',
    'duration_per_line': 4
}

response = requests.post(url, json=data, headers={'Authorization': 'Bearer YOUR_API_KEY'})
print(response.json())
curl -X POST https://ffmpegapi.net/api/videos/add-text-overlay-captions \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer YOUR_API_KEY' \
