You can use an Expression node to automatically patch them with a float
value; here's an example that does a black replacement:
set cut_paste_input [stack 0]
version 6.3 v1
push $cut_paste_input
Expression {
expr0 "isnan(r) ? 0 : r"
expr1 "isnan(g) ? 0 : g"
expr2 "isnan(b) ? 0 : b"
name nanFix
selected true
xpos 88
ypos 47
}
You could also use a MergeExpression to auto-patch from another or image;
the expressions would just need to be changed to pull from that input
instead of applying a float value.

Subject: [Nuke-users] nan in mr renders
what's the best way to deal with these in nuke, other than getting new
renders? we have a render from mr that we patched with another frame, but is
there a way to:
a) analyze a sequence to figure out where they are occuring?
b) patch/fill/whatever
just curious how people around deal with those in a pinch
