I need to get the videos off my phone to get more space again
Open iPhoto on your Mac and connect your iPhone. Then iPhoto will import your photos and videos. Then you can manually delete the videos from your iPhone or let iPhoto delete all of the photos and videos from your iPhone and add the photos back to the Phone via an album and iTunes syncing.
Or, launch Image Capture, connect your iPhone and selectively download to where ever you'd like and erase just the videos from your iPhone using your iPhone.
