The Virtix 16x9 Converter takes the guesswork out of converting 16x9 footage to standard 4x3 footage by eliminating the need to choose a letterbox size or determine how much to vertically "squeeze" the video. Since the Virtix 16x9 converter has no sliders to set, all your letterboxed video footage will match up perfectly, even if you convert your clips individually at different times. The Virtix 16x9 Converter has been written from the ground up to give the sharpest and fastest results possible.
