You cannot email videos directly from iPhoto.
Select your video in the event, then go to the main menu bar and use the command "File > Reveal in Finder > Original File". Select the video in the Finder and drag it onto the "Mail" icon to send it.

Many email services have an attachment limit if 20mb and some an atachment limit of 10mb. That means that video is rarely suitable for emailing. Options:
Upload it to a sharing site like YouTube or Vimeo and email a link - these will allow the recipient to view the material onlne.
Upload it to sharing services like Dropbox or YouSendIt and email a link. This will require that they downoad the material to their machines to view.
