Ah, of course. For some reason I thought those Auto Use Table were required
for viewing the 16bit images properly in the viewer. Thanks for sorting that!
And yes, the writing bug (well, no "Permission problems" feedback anyways)
certainly did save me a lot fo grief in the end.

Bugs! However in this case it's preventing you to make a mistake.
To paint correctly on DPX, Cineon, do this :
in the User Preference | Compositing | Cineon DPX -> Automatically Use Table.
..
turn off both "When Reading File", "When Writing Files".
In the FX Viewer, go View|Viewer Preferences,
turn on Look Up Table, switch to Cineon. Now create the paint clip.
This insures that your cineon filess 'pass through' the compositor
unmodified. The log-to-lin will occur at display time.
In the 'automatic apply LUT' setting, pixels below black and above
white at clamped.

Conversation: Using the FXtree for dirt fixes.
Subject: Re: Using the FXtree for dirt fixes.
Should this work if the file is Cineon? I'm just using the merge tool
solution at the moment, but I've run into two snags.
First I was working on images over the network... and when it came time to
Save Modified Frames it didn't seem to write the changes back, no matter what.
So I moved the files local to see if it was just a network related problem.
Working locally did indeed help - it wrote over the saved images - but it looks
like the autodelog/autolog business fell apart somewhere along the way because
the image is radically different. Ugh.
Are there some things I need to know about Cineon/DPX files and the raster
paint? I was merging from the same image sequence so it isn't a matter of
mixing 8-bit and 16bit formats... Any ideas?

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.

Subject: Using the FXtree for dirt fixes.
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
