ok digging with the command prompt i found a deeper error

i run this at the cmd prompt:

blur2d -l 1 -s 1 -m 2 -r 0 -n 0 60 1 -p 1 -f C:\Apachetemp\color\Apache_AnimationB.iff -v C:\Apachetemp\motion\ahBG.iff

and i get back an error

C:\Apachetemp\color\Apache_AnimationB.iff -v C:\Apachetemp\motion\ahBG.iff
C:\Apachetemp\color\Apache_AnimationB.iff.0 + C:\Apachetemp\color\Apache_Animati
onB.iff.0 ==> C:\Apachetemp\color/Apache_AnimationB_blur.iff.0
Error in reading the motion vector file C:\Apachetemp\color\Apache_AnimationB.if
f.0

so the -f flag is causing the problem, but the color image has no motion vectors obviously...but the -c flag doesn't allow blur2d to see the input file.

any suggestions?
