Hi all,

I am trying to generate a movie (MPEG-1) and I select also image smoothing and half-size rescaling. When I use image smoothing I get the following error:

pnmsmooth: Running Pnmconvol -normalize -matrix=1,1,1;1,1,1;1,1,1
pnmsmooth: Running Pnmconvol -normalize -matrix=1,1,1;1,1,1;1,1,1
    while executing
"::exec /usr/local/bin/pnmsmooth /Users/sapik/Desktop/orig.flow_2ndhalf_movie_2b.00000.ppm > /Users/sapik/Desktop/flow_2ndhalf_movie_2b.00000.ppm"
    ("eval" body line 1)
    invoked from within

"uplevel #0 [list $w invoke]"
    (procedure "tk::ButtonUp" line 23)
    invoked from within
"tk::ButtonUp .movie.goabort.gobutton"
    (command bound to event)

Any ideas how I could fix it?
