How to identify clips while comparing them?

[fabiospark]

I'm using this little script to compare different MVTools settings. Is there a simple way to identify the clips - maybe with a superimposed a, b, c, or d to be sure which is which?

a=avisource("Fabio slomo 1.5 blksize 4.avi")
b=avisource("Fabio slomo 1.5 blksize 16.avi")
c=avisource("Fabio slomo 1.5 blksize 8.avi")
d=avisource("Fabio slomo 1.5 blksize 16.avi")
Stackvertical(StackHorizontal(a,b),StackHorizontal(c,c))


Thanks.

etc
