I'd like to create a front page video feature that embeds a vimeo video of the users choosing. I'd like the user to only have to input the video code. For instance, for http://vimeo.com/24474320 - I'd like them only to have to input "24474320".
Should I use custom post types for this? If so, how do I set this up so that it limits the field size? I'm just getting started, and I'm relatively new at wordpress, so I don't need to get into specific code necessarily - it's more of a strategic question. How would you tackle this?

It would be awesome if all the user (backend) saw was this:
FRONT PAGE VIDEO FEATURE
Vimeo URL: [____________________________]
Then I would call that video into the front page feature.
