In today's digital landscape, video content is king. Whether you're creating marketing materials, educational content, or engaging TikTok videos, adding captions can increase viewer engagement significantly. FFMPEGAPI.net offers a powerful AI Captions feature that allows developers to easily transcribe videos and render styled captions with just a few API calls, all without the hassle of managing FFmpeg infrastructure.

What is the AI Captions Endpoint?

The AI Captions feature of FFMPEGAPI.net is a hosted REST API that transcribes your video audio and creates TikTok-style captions. This endpoint is designed to streamline your video content creation process, allowing you to focus on what matters—creating great content.

  • Transcribes audio and provides word timestamps.
  • Renders styled captions directly into the video.
  • Returns URLs for caption artifacts when available.

How to Use the AI Captions Endpoint

To use the AI Captions endpoint, simply make a POST request to the following path: /api/videos/add-tiktok-captions. You will need to provide a video URL and can customize various parameters to fit your needs.

  • Required Parameter: `video_url` - URL of the video to process.
  • Optional Parameters: `subtitle_style`, `language`, `aspect_ratio`, `max_chars_per_line`, `max_lines`, and `position`.
curl -X POST https://ffmpegapi.net/api/videos/add-tiktok-captions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"video_url": "https://example.com/video.mp4", "subtitle_style": "yellow-bg", "position": "bottom"}'
import requests

url = 'https://ffmpegapi.net/api/videos/add-tiktok-captions'
data = {
    "video_url": "https://example.com/video.mp4",
    "subtitle_style": "yellow-bg",
    "position": "bottom"
}
headers = {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
}
response = requests.post(url, json=data, headers=headers)
print(response.json())
