Anyone familiar with Digital fusion (DFX+ 3.03)?

I was wondering if anyone could help me with the output format... I have a bunch of .TGA in High defenition format, I need to make a clip out of them but I cant seem to keep the same aspect ratio. The result is a "zoomed in" version of my original frames, I have a loader and a saver module,, I tried to tweak the settings to get the HD output format but didnt succeed so far.

any help (im actually looking through the manual and several sites for help).

thx for any pointers!!
