Hasta La Motion!

hi!

maybe this is a stupid question, but i can’t for the life of me figure out how to do it

let’s say i bring in an object/objects into nuke from a 3d-app and then create additional fx-elements in nuke…think water-splashes on cards for example.
or even more simple…different scanlinerender-outputs in nuke and i want to use the 2 as holdouts for each other.

is there a way to use one as the holdout for the other so that it’s "matted out" basically!?

i tried using zmerge but that doesn’t do the same thing. also i’ve gone through various layermodes in combination with zmerge…but that all lead me nowhere it seems

thanks in advance for any help!

cheers

Ok, we’ve got a project where we’re working with S-Log plates and Linear 3D files.
I’m trying to sort out the pipeline for Nuke, but i’m having a bit of trouble.
In shake we’ve got it set up like this:
-S-Log to Lin node
-Lin to S-Log node
-Cinespace viewerlut to view the S-Log files, to see what the grade will do to them.

What i’ve got so far in Nuke is:
-S-Log curve for read nodes
-.3dl file from cinespace/cinecube
-expression nodes (with same expressions as the shake Slog-lin nodes)
-vectorfield node set to viewer_input (with the .3dl file, and color space in to S-Log and colorspace out to sRGB)

When I view an S-Log file (with the colorspace set to S-Log) with the vectorfield node, it looks really similar to what i see in my shake viewer with the cinespace lookup (but still the whites are a tiny bit brighter).
But it doesnt make sense to put the vectorfield input to S-Log does it? If i set it to sRGB, the whites get a bit too bright compared to what I see in the Shake viewer.

Ugh…it’s getting a bit confusing. Or is it that it’s never going to look completely look the same as in shake?
Can someone recommend me the correct way to set this up?

Thanks,

Tom

Hi!
We’ve noticed at work that any kind of small scale up to an image (I’m talking 2k) generates a checkerboard pattern to it. Let’s say I scale up the image by 1.005, the image is scaled up but if you zoom in you can see this sort of grid or checkerboard pattern on it, it seems that some pixels are scaled up and other are left the same …
I’ve tried all filters and to get rid of the problem using all possible nodes:

-Transform
-Card3D
-iDistort
-CornerPin
-Reformat
-GridWarp
-STMap
-Card and scalineRender

Anybody knows about it?
Thanks to all,

.p!

I am trying to get to grips with the Shake to Nuke transition but I have had enormous problems with filters. I find it very hard to cornerpin track non-square pixel footage without suffering softness/aliasing upon unsquished playback within FCP.

In Shake, I would mostly only ever use:

lanczos (most of the time)
default [mitchell/sinc] (if I was being lazy)
mitchell (if lanczos still had artifacts)
sinc (if lanczos was still too soft)
impulse (if I couldn’t be bothered to keep rounding off subpixel values on pans)

But, in Nuke, only Mitchell shares the same name, and none of them seem to work nearly as well as Lanczos.

Does anyone with more Nuke experience have any idea what the best transform filters are for use in what circumstance in Nuke?

This would even be a very helpful thing to add to the Shake to Nuke transition guide methinks.

hi..

Any one explain Furnace steadiness … how to use effectively …

i want to smoothen my shot..

plz explain ?

thanks
