Error when using upload

[petems]

I'm using a script that has the following Vimeo Upload like this:

upload = Vimeo::Advanced::Upload.new(@consumerKey, @consumerSecret, :token => @token, :secret => @tokenSecret)

  setTitle = Vimeo::Advanced::Video.new(@consumerKey, @consumerSecret, :token => @token, :secret => @tokenSecret)

  video = upload.upload(file)
  @video_id = video["ticket"]["video_id"]
  puts "Vimeo Video ID: #{@video_id}"
  setTitle.set_title("#{@video_id}", "#{@title}")

When I run that against a mp4 about 64MB, I get this error:
