I need to insert (into a powerpoint 2010 slide) an avi video of one photo morphing into another. I used FotoMorph. I have another video someone else did years ago with 2 different photos, and this one is only 845KB (an avi file, bitrate 223). BTW, I'm using Windows7. The newly created avi file size is 486MB! (bitrate 132,710). Way too huge. How can I reduce it to match the older one? Many thanks for any help. I'm not at all an expert on this.
