Q: How to send an individual video back to the cloud

Hi jrm2010,

Welcome to the Support Communities!

If you have purchased and downloaded a movie or TV show from the iTunes store, it will always be availabe to redownload (unless it is removed from the iTunes store inventory.)  So, you can delete it from your iPad to make room for more content.

The following articles will provide more information:
