rotoscope bullet hole problem

I used a fake stick on bullet hole during a recent shoot and now Im trying to erase the edges of the plastic in photoshop.

The sequence is about 29 frames long. I exported out of Final Cut and imported into Photoshop and used a blur tool to removed the line. When I reimported back into the finalcut timeline I see the blurr effect shimmers and draws more attention to teh problem than before.

The sequence is regular 29.9 interlaced video. Is this part of the problem? Photoshopping an interlaced frame? Should it be converted to a progressive format first?

RAther than the blur tool what is a better method to fix this problem?

Convert to progressive
Then use a blur mask thats just a a soft ring where the edge of the plastic show up. track that and adjust its shape and stuff to suit any camera moves.
Convert back to your original interlaced framrate to put back in your edit
 
since the sticker has irregular edges trace the edge shape with a mask
track that mask to any camera moves
then edit the shape of the mask frame by frame if it changes.
stroke the mask and give it soft edges and then use that mask to lay a blurred version of the foogate over the highlights on the sticker edge.

you might be able to track a cloner brush in there, but thats more complicated if there are camera moves and probably unneeded.
 
what is the procedure for converting to progressive and converting back to interlaced? Can you be more specific on how to apply the blur effect?
 
Okay, this may take a little longer, but go in with the clone tool (the one that duplicates pixels from one portion of the image and paints them elsewhere) and a really small brush, like 2 pixels wide and cover up the light edge of the plastic with the nearest properly colored pixels. If it is too harsh, make it more transparent. I just tried it to the sample image you supplied and it looked pretty good.

I'm not sure how it will look when viewed in motion, but I would give that a try.

I can't answer the interlace vs. progressive, but given the choice I would choose progressive.

PS. it all about zooming real close and doing it pixel by pixel.
