How to Use the Image and Audio Merge API

To utilize the Image and Audio Merge feature, you make a POST request to the endpoint at '/api/merge_image_audio'. The request can be structured to include arrays of image URLs and audio URLs for multiple pairs, or single image and audio strings for a simple merge.

  • image_urls (array): URLs of images for multi-pair requests.
  • audio_urls (array): URLs of audio files, each corresponding to the images.
  • transition_effect (string): Optional effects such as fade or wipe.
  • zoom_effect (boolean): Enable a slow zoom on each image.
import requests

url = 'https://ffmpegapi.net/api/merge_image_audio'

    'image_urls': [
        'https://example.com/intro.jpg',
