I have imported an MPG4 file and edited it. I have started to export it back to mpg4. The original movie was 1 hour 46 minutes. The edited movie is 1 hour 19 minutes. It took MEp about 20 seconds to import the file. It has now been more than 1.5 hours and still MEP isn't even close to a quarter of the way through exporting to MPG4.
Why does this software take an eternity to export the file?
