CarrierWave Video - Transcoding passes but video not uploading

The transaction to the server is being made, but as soon as the page refreshes, the server rolls back. My log file is below, and I will also post the contents of my video_uploader.rb Can you help me figure out why this issue is occurring. I've tried everything, and I'm unable to get the file to properly insert into the Db.
