I am having trouble adding chapter tracks inside quicktime if anyone can help me out. I exported a .txt, opened it up in quicktime, exported with descriptors. Then opened up the text and added the timecode under each title and put the duration timecode in the last spot where no title exists. When i try to import into quicktime it tells me "The movie contains an incorrect duration" I double checked everything and still get the same message. One time I put timecode except for # of frames and then deleted the last descriptor that had no title and it worked but it went to the wrong part in the video (obviously it was frames off). I tried adding the right frames and got that message about the duration. Can anyone help out?
