Thanks a lot for the reply, Luc-Eric, I appreciate the step by step. In light
of your warning, and in the general interest of working non-destructively for
as long as possible, what would be the best method for just painting a black
and white mask and using that in a comp node(Over?).
Sorry for the basic questions, but I've never been certain how exactly the obey
matte inputs work... does it just look at the alpha of the input, or could a
black on white, raster painted clip be piped in? Or is that even the best way?
I keep wanting to plug a weight map into the blending parameter of the Over
node. :)
Thanks again,

First you need to ask if you want to use vector paint or raster paint.
Since this is scratch removal, then raster paint is best because all the
paint strokes will be only one frame long.
So you create a 'paint clip' (aka raster paint clip) with the source images.
Then you create a file input for the 'clean plate'. If this clean plate is
the same, but with a different offset, simply do as you did, load it a second
time set an offset.
Double-click that Paint Clip to start painting.
Now select a brush such as the 'Merge' brush. The Merge brush paints with
the pixels from the Merge Source. The clone brush woud paint with pixel from
the same image. Other brushes paint solid colors. You can use the 'brush'
tool, or the 'line' tool to paint.
Right-click on the File Input with the clean plate. In the menu, choose
'Merge Source'
Now paint on the paint clip : you should now be painting with the pixels from
your clean plate.
You can use the 'bg/fg' button in the FxViewer to see a blend of the merge
source and the paint destination. Right Click on the viewer to start picking a
different merge offset if you need one.
Word of warning : Raster Paint will save the modifications directly on top of
the orginal image, either when you click 'save' on the PPG, or CTRL+S to save
your scene. You may want to back up the original frames if you do not want to
loose them! You would normally use that back up as you clean plate.

Hey List,
Can someone describe a good workflow for using the fxtree to fix up some
scratches? Essentially, I want to be able to clone from a different frame.
What I've tried so far is to basically load the sequence in twice, with a one
frame offset on one input node. Then combine the two in an Over node. But at
that point, I'm kind of lost on where to go.
I'm thinking I could somehow either paint on the alpha of the offset input,
or create a new paint clip and pipe that into the Obey matte input of the Over
node?
I will be RTFMing, but any ideas would be appreciated.
Thanks,
Jean-Paul LeDoux
