In this article, we'll explore how to programmatically add text overlay captions to your videos using the /api/videos/add-text-overlay-captions endpoint.
Understanding the Text Overlay Captions API
The Text Overlay Captions API is an essential tool for developers looking to enhance their video content with captions. This API allows you to render user-provided text lines over videos, displaying one line at a time for a specified duration. With simple JSON requests, you can add personalized messages or subtitles to videos stored online.
- Display user-provided captions over videos.
- Customize subtitle style, position, and duration.
- No need for local FFmpeg setup.
How to Use the Text Overlay Captions Endpoint
To use the Text Overlay Captions feature, you need to make a POST request to the /api/videos/add-text-overlay-captions endpoint. The request should include the video URL and the desired text lines. You can also customize the subtitle style, aspect ratio, position, and duration for each line.
- Endpoint: POST /api/videos/add-text-overlay-captions
- Content-Type: application/json
- Authentication required with API key.
import requests
url = 'https://www.ffmpegapi.net/api/videos/add-text-overlay-captions'
headers = {'Content-Type': 'application/json', 'Authorization': 'Bearer YOUR_API_KEY'}
data = {
'video_url': 'https://example.com/video.mp4',
'text': 'First line\nSecond line',
'duration_per_line': 4
}
response = requests.post(url, headers=headers, json=data)
print(response.json())API Parameters Explained
