I have a GIF file that is 300 pixels wide by 50 pixels high. I would like to
add audio ot it and export it as a .wmv which is still 300 by 50.

I can't find the settiing in Windows Movie Maker to keep this size. It
currently stretches it vertically to fit it into 4:3 or 19:9 aspect ratio.

All assitance gratefully received,

Peter
