Loading of node edit form with multiple ooyala embed code attached to it results in timeout

Hello,

I am aware that ooyala field doesn't support multiple embed code for a single node, but for a specific requirement we need this functionality to work. for this we are adding a line in form_alter hook for ooyala field that is giving 'Add another video' button.

$form['field']['cardinality']['#default_value']= -1;

But with this approach we are sometimes running into a issue when we try to edit a node with multiple embed code attached to it. Sometimes edit page load fine but sometimes it takes too much time and result in timeout error. But when i embed only single video to a node it works fine.

Does ooyala limitation to not provide multiple video for a singe node has anything to do with this...I am bit confused
