You can convert it with BLINK video and then save it in Windows Movie Maker
to make the file size in creditably smaller as well as the viewing screen part.

heres the link to get BLINK video(its free)

once you convert it into a .avi format you can then 'import it' into
Windows Movie Maker and then re-save it,, and it be much smaller in file size.

hopefully that made sense.
