A suggested change for better accuracy; instead of:

+    my $source_aspect = $width/$height;
+    my $target_aspect = $self->aspect_ratio;
+    my ($w, $h) = split(":", $target_aspect);
+    $target_aspect = $w/$h;
+
+    my $export_par = sprintf("%d,100", 100 * $target_aspect / 
$source_aspect);

I'd suggest:

   my ($target_w, $target_h) = split(":", $self->aspect_ratio);
   my $export_par = sprintf("%d,%d",
     $target_w * $height, $target_h * $width);
