I've used Photo Story 3 in the past and loved it.   I have Windows 8 so trying to use Movie Maker.  I believe it has nice features.  What I find odd is that I brought in 200 pictures that total 30MG but the movie file (MP4) created is over 400 MG.  If I use the YouTube format it is around 200 MG. I still find that extremely large since pictures only total 30MG.  I discovered changing time for each picture (from default of 7 seconds to 3 seconds) cuts the file size in half.  Is there something that can be done to compress the MP4 file?
