I do a similar thing, but as mpeg compression gets blocky I do this:
set cut_paste_input [stack 0]
version 8.0 v6
push $cut_paste_input
Radial {
area {512 389 1536 1167}
softness 0
name Radial1
selected true
xpos 47
ypos -194
}
Dot {
name Dot1
selected true
xpos 81
ypos -159
}
set N220bb0 [stack 0]
Transform {
scale 0.125
center {1024 778}
filter Impulse
name Transform1
selected true
xpos -63
ypos -110
}
Blur {
name Blur1
selected true
xpos -63
ypos -86
}
Transform {
scale 8
center {1024 778}
filter Impulse
name Transform2
selected true
xpos -63
ypos -54
}
push $N220bb0
Merge2 {
inputs 2
operation difference
name Merge1
selected true
xpos 47
ypos -30
}
push $N220bb0
Merge2 {
inputs 2
operation hypot
name Merge2
selected true
xpos 148
ypos 22
}
