Introduction to Merging Images and Audio

Merging images and audio can enhance storytelling and user engagement in videos. Whether you're creating a presentation, a tutorial, or an artistic video, the ability to synchronize visuals with audio is crucial.

Using the Merge Image and Audio Endpoint

The endpoint for merging images and audio is easily accessible via a POST request to `/api/merge_image_audio`. This endpoint allows you to create dynamic videos by providing arrays of image and audio URLs.

You can customize the video further with transition effects and dimensions.

  • Endpoint: `/api/merge_image_audio`
  • Method: POST
  • Content-Type: application/json or multipart/form-data
curl -X POST https://www.ffmpegapi.net/api/merge_image_audio \
