I have several .Gi files on my computer and I want to use them to make a short movie on Edius form Canopus. Thei are image files with the .gi extension.
According to this http://filext.com/detaillist.php?extdetail=gi&Search=Search your file are image files so or make a cd with them or extract the video file with any iso tool like IsoBuster or Magic Iso or Ultraiso or just use the Daemon Tools to play the files.
