I am attempting to export a self contained quicktime file of a 90 min feature film for a friend of mine. The frame rate is 23.98. Pixel Aspect Ratio is 1280x1080. We keep getting a General Error Message anytime we try to export a Self Contained Quicktime file. When we go to export a H264 it won't even let us do it. It says that there isn't enough free space. Which is impossible because we have over a TB of space. Any suggestions?
