i took a random   MP4 file    of 68 KB     and saved it in Movie Maker and Free Video Editor at the various format options:

MM hi def         1,993 KB

MM for Comp     609 KB

MM for Email      216 KB

FVE ConvToAVI    125 KB

FVE ConvToMPG    88 KB

FVE Save as Orig format   68 KB

Saving in MM any file joining is catastrophic.

any other MSoft video file editing Apps?
