Thanks again for the awesome script. I modified it slightly to allow for use of pixel types other than YV12 (without altering the input clip pixel type).

# Should supply non zero th OR change SkipGreen default.

    th=Float(Default(th,0.0)) # 0.0==Search for 1st exact match or best possible if no exact match found]. Threshold 

for declaring match (diff <= Thresh).

    DClip = (!LastGreen) ? DClip : DClip.Reverse
    Green=c.BlankClip(Length=1,color=(R*256+G)*256+B,pixel_type="YV12")
