Need help with showing information in a limited space

Well, it is my first time seeking help for user experience design, so pardon me as I am not accustomed to the proper rules.

I have an information card which shows a thumbnail for a video and below it, information about that video is displayed. The layout is basically like this,

enter image description here

Well, the difficulty is that the application allows user to add multiple number of fields and value, which means that along with video title and details. The user can add 10 more fields with corresponding values.

I was thinking of using a modal to display additional information about the video, is there any better way as I am not so sure about it.
