How to Make a Request to Add Captions
To utilize the AI Captions feature, you need to send a POST request to the endpoint with the required parameters. Below is a practical example using Python to illustrate how you can add TikTok-style captions to your video.
import requests
url = 'https://www.ffmpegapi.net/api/videos/add-tiktok-captions'
headers = {'Authorization': 'Bearer YOUR_API_KEY', 'Content-Type': 'application/json'}
payload = {
'video_url': 'https://example.com/video.mp4',
'subtitle_style': 'yellow-bg',
'position': 'bottom'
}
response = requests.post(url, headers=headers, json=payload)
print(response.json())Parameters for Customizing Captions
