I just got Roxio Toast 12 and not sure what is going on. I have a file that is 3.91 GB, its a quicktime movie exported from FCP Apple ProRes 422 (HQ), Linear PCM... my question is, when I go to make a DVD of the movie i drag and drop it and toast 12 says 161.7 MB on disc - SPACE REMAINING 4.32 GB. Is toast 12 compressing my file? Really confused why a 3.91gb file is only taking up 161.7 MB. Please advise!! thanks!!
