Merge Audio & Video for Instagram/Facebook

Merge video and audio from Instagram/Facebook and other sources

Overview

The difference between Get Direct Link and Download and Merge is that the video will be downloaded, audio and video will be merged and then the share link will be created

Proxy is required to get the list of download links.

By default the video will have no sound. This method is only for those who want to download videos from Instagram/Facebook with audio available.

The mergeAV field currently only works on: Facebook, Instagram

In the future, if social networks or other platforms separate audio and video, updates will be supported by a field called mergeAV, which is used to combine audio and video.

Because the video is downloaded, it will consume more proxy usage capacity

API Request

Endpoint: https://api.apify.com/v2/acts/wilcode~all-social-media-video-downloader/runs?token=<YOUR_API_TOKEN>

Method: POST

Headers:

{
  "Content-Type": "application/json"
}

Request Body:

{
  "url": "https://www.facebook.com/reel/1231817508603093",
  "proxySettings": {
    "useApifyProxy": true,
    "apifyProxyGroups": ["RESIDENTIAL"],
    "apifyProxyCountry": "CA"
  },
  "mergeAV": true
}

If you are integrating Actor as download API, you can always set mergeAV value. When the url supports mergeAV it will automatically merge Audio and video, when url not support it will not be affected

This will help the API get all the urls and when the url is supported it will be automatically merged

      }
    ]
}

The list of download links and resolutions will be listed in the formats attribute.

When the body has the mergeAV field, the result will have an additional download field

In the download field there will be the url and resolution

The download url is the file saved in your Storage (Apify), this link will be automatically generated

This link will automatically expire and the file will be deleted from your Storage in 7 days.

Why does the video sometimes crash while downloading?

• Due to unstable proxy, the video download fails while downloading

• You need to change proxy or change proxy country (if using Apify Proxy)
