Shake to Nuke transition guide

[Hugh]

In the same way that there's a Shake to Fusion transition guide that explains what the Fusion equivalent of each Shake node is, I've spent some time recently compiling something similar for Shake to Nuke.

So far, I've got to the end of the Layer nodes. Even though they aren't, I've included the NFX plugins on the Nuke side.

If there's anything in here that you think should be different (I don't know Nuke well enough in a lot of places) then please let me know.

Eventually I'll put this on a standalone website (is there a Nuke-based Wiki?)

Any Nuke node that begins with "N_" is part of the NFX Plugins bundle which is a free external plugin suite.
The Fields Kit gives Nuke the functionality to deal with interlaced footage.

(+) Means that Nuke's is better
(-) Means that Nuke's is worse
(=) Means that Nuke's is the same
(?) Means that I've not used it enough (in one or other package) to make a reasonable comparison
(~) Means that Nuke's is different
(X) Means that Nuke, as far as I am aware, doesn't have it or a direct equivalent

ISharpen (X)
Median -> Median (+)
PercentBlur -> Blur (+)
Pixelize -> Blocky (=) Blocky isn't in the main menus, but can be found under "Other -> All Plugins -> B" (need to press "update menu"). This may be because it's buggy.
RBlur -> GodRays (~)

ZDefocus -> ZDefocus (?) The ZDefocus node isn't in the main menus, but can be found under "Other -> All Plugins -> Z" (need to press "update menu"). This may be because it's buggy.

And the "Transform" tab in Shake...

Transform
AutoAlign (X)
CameraShake -> CameraShake (+)
CornerPin -> CornerPin (+)
Crop -> Crop (=) with "reformat" on

Shear -> Transform (-) Only does X shear (skew)
Stabilize -> Tracker (+)
SmoothCam (X)
Tracker -> Tracker (~)
Viewport -> Reformat (~) with "resize type" on "none"
Window -> Crop (=)
Zoom -> Reformat (-) Doesn't allow you to set a zoom level

[Hugh]

Warp
DisplaceX (X) Although STMap does UV texturing
IDisplace -> IDistort (=)
LensWarp -> PerspDistort (-)
Morpher (X)
PinCushion (X)
Randomize -> N_Scatter (+)
Turbulate (X) Workaround with N_Rand, scaled up (Transform) then the R and H channels copied into forward.u and forward.v of the image to turbulate. Then use an IDistort node.
Twirl -> Twist (?) Twist isn't in the main menus, but can be found under "Other -> All Plugins -> T" (need to press "update menu"). This may be because it's buggy. You need to up the "Mesh Density" otherwise it'll just look like it's rotating.
Warper -> SplineWarp (+) with "mapping" on
WarpX (X)

[Hugh]

Other
AddBorders (X)
AddShadow (X) But so easily doable by hand
Bytes (X) Unneeded - everything is float internally
Cache (X) Not as a node, but I believe CTRL-B on a node does the same thing
DeInterlace (X)
DropShadow (X) See AddShadow
Field (X)
Histogram -> Histogram (~) More like PhotoShop's "Levels"
PixelAnalyzer -> CurveTool (+)
PlotScanline -> Sampler (~) Shows it as a curve rather than drawing on screen
Select -> Switch (=)
SwapFields (X)
Tile -> ContactSheed (+)
TimeX -> TimeWarp (+) or any of the other Time nodes. Anything's better than Shake's TimX
TLCalibrate (X)
Transition -> AppendClip (~)

One thing I can't find anything for in Nuke is interlaced footage.... The only thing I can find that even thinks about interlacing is the 3:2 Pulldown and 2:3 Pullup nodes....

Any ideas?

Diogo's Fieldskit: http://www.fxshare.com/nuke/download...sKit-4078.html

I don't have it in front of me and I'll check when I get home, but SURELY Nuke can do IBlur - that's just a crazy omission!

[Hugh]

Thanks for that - I've added it at the top.

IBlur could probably be done with ZBlur.

In Shake, IBlur is just a macro that turns the second input into a Z channel and then uses ZSlice to KeyMix between various different blurred levels of the source image. I'm sure that could be set up in Nuke....

[abishek]

Wow... Thanks Hugh. Appreciate it.

[Aruna]

A lot of what you have in Color can be done with one node in Nuke, for example,

Compress, Expand, Clamp, Multiply, Gamma, Blackpoint, Whitepoint, Brightness can be put into Nuke's Grade Node. Some become obsolete, like Shake's Fade. That becomes a mix in every single node (or you could use a multiply). Some cleared up examples.

Shake | Nuke
Add | Color-Math-Add
Clamp | Color-Grade
Compress and Expand | Color-Grade
Brightness | Color-Grade or Color-ColorCorrect
Saturation | Color-ColorCorrect or Color-Saturation

[Hugh]

Nuke's Add, though, can't add a colour - it can only add the same value to all of the selected channels.... Which is why I put N_Add in there.

I didn't realise that Grade had a clamp in - I'll have to have a look when I'm back at work on Monday.

I do want to make it so that there are more options per Shake node - for now, I've just put the node that works closest to how the Shake node works.

Thanks for the comments, though

Thanks for doing this Hugh!

For Add, just unselect the channel you don't want to add to. I haven't fiddled with N_Add, so it maybe has some different functionality.

thanks for doing this!

[nikita]

Awesome list, thanks for taking the time to write it up.

I have played with Shake a very short while a long time ago.I remember that the ColorReplace node was fun for me at that time.I discovered the "color replacement" function in Nuke's "HSV Tool" node but it's not that fun as the result don't please me to much.Is there a nuke way/ node/ script that would allow me to replace
a whole range of rgb values with another range or a single value? The hsv tool allows me to replace only a single value with anothe value.
