What am I missing? I am archiving some movies to DVD. I have them in MP4 format. So, to get them onto the DVD, using iDVD, I'm first importing the MP4 to iMovie (as iDVD won't burn the mp4). I then "Share" the movie that saves it as a .mov. This then is easily put on the DVD with Magic DVD. Done this twice no issue. However, on the latest, the mp4 says it's 2.19gb. Great. But when I import to the iMovie and go to save the .MOV to file, the movie is now 78GB!!!! None of the settings have changed: Still "Best" and "PRO" and no custom and not "BEST QUALITY." 720. 2.19gb ...then suddenly 78gb .... only way to get it under 5gb would be to save at 2mps... and that isn't going to work. Any idea as to what's going on?
