I have a requirement to tape a 1 hour video/audio Webconference that results in about 30 mb. of Data. When I then publish it into a MP4 or WMV format, it "explodes" into a 200mb or larger file. Furthermore, when I use Microsoft Movie Maker to do this act, it gets about 73% done and stops. I have downloaded several "free" programs to do this conversion and when I do, they too get 2/3rds the way through and then want $50 to buy the upgrade. Does anyone have any ideas where to get Freeware or something that actually works to do this type of conversion/compression?
