Add cron schedule to upload video on save_post

I made a custom plugin to get post data from another source, when I save a post, I get all data. and also upload a video from source server to our server.

But it take a while when saving post until uploading the video.

Now, When saving post I need to get all data from source, But schedule uploading video after 1 minute to upload it on background.

The Code Example:

add_action( 'save_post', 'update_from_source');
function update_from_source($post_id)
    {
        // code for getting post data here
    function uploading_video()
        {
            // code for uploading video here
            // I dont need to run this when saving post
            // but add it as cron job for this post
        }
    }

How I can Add uploading_video Function to cron?
