To make your embedded videos automatically 580px wide just add this in your functions.php file:

if ( ! isset( $content_width ) )
	$content_width = 580;

It should work, but if you need to take responsive theme into account, i’d suggest you use fitvids.js . Just add this line to your fitvids.js if you happen to use it:

"iframe[src*='animoto.com']",

You’ll notice where this line fits, so the whole part will look like this:

return this.each(function(){
      var selectors = [
        "iframe[src*='player.vimeo.com']",
        "iframe[src*='youtube.com']",
        "iframe[src*='youtube-nocookie.com']",
        "iframe[src*='kickstarter.com'][src*='video.html']",
        "iframe[src*='animoto.com']",
        "object",
        "embed"
      ];
