In today's digital landscape, enhancing video content is crucial for engagement. Adding text overlay captions can convey important information, improve accessibility, and enhance the viewer experience. FFMPEGAPI.net offers a straightforward way to add text overlay captions to any video using its robust hosted REST API, helping developers streamline their workflows without the need for server setup or complex infrastructure management.
Understanding the Text Overlay Captions Endpoint
The Text Overlay Captions feature allows you to render user-supplied text as timed caption overlays on videos. This endpoint is particularly useful for developers who want to automate the captioning process in their applications or for content creators looking to enhance their video offerings.
The endpoint is easy to access via a POST request to `/api/videos/add-text-overlay-captions`. You can specify various parameters to customize the appearance and timing of the captions.
- Render multiple lines of text as overlays.
- Customize subtitle styles, position, and duration.
- Ideal for video automation tools used in AI agents.
Required and Optional Parameters
To effectively use the Text Overlay Captions endpoint, you'll need to provide the following parameters:
1. **video_url**: The URL of the video you want to overlay text on. This is a required parameter.
2. **text**: The caption lines you wish to display, separated by newlines. This is also required.
Additionally, there are several optional parameters that you can specify to further customize your captions:
- subtitle_style: Choose from styles like plain-white, yellow-bg, pink-bg, blue-bg, or red-bg (default is plain-white).
- aspect_ratio: Set to 16:9, 9:16, 4:3, or 3:4 (default is 9:16).
- position: Specify caption alignment (top, center, or bottom, with center as the default).
- duration_per_line: Control how long each line appears (1 to 30 seconds, default is 5).
Practical Example of Using the API
Here's a practical example of how to use the Text Overlay Captions API with a sample video and text. This example can help you understand how to implement the API in your own projects.
import requests
url = 'https://www.ffmpegapi.net/api/videos/add-text-overlay-captions'
headers = {'Content-Type': 'application/json'}
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)
