“no Keyframes are selected”

Hi all,
is it me? No matter what I select in the curve editor, when I goto edit/move i get error " No keyframes selected"
For example, I created a roto shape, keyframed some movements, go into the curve editor , select every combo of curves possible, and get this error.

Here is the image..
thanks,
Lou

Cloning a Camera by scripting

Hello everybody,
I’m working with Nuke 6.0v1 64bit and I’m developing a python script to set a stereoscopic scene.

I having trouble in cloning a Camera node with Python, using the method nuke.clone().
Nuke makes the new node but all knobs are not connected, so even if graphically the two nodes are cloned (with an orange arrow), in facts they’re not.

When I use the Alt+K command for cloning, it works (but of course I need my script does the job!).

I’m attaching a screenshot, where you can see this strange thing.

My code is:

Code:

camera1 = nuke.createNode("Camera")
camera2 =  nuke.clone(camera1)


What I’m doing wrong?

Thank you very much for your help!!

expression in text node

Hello forum,

I have a text node which I want to print out the current seconds. My expression is very simple:
int[[frame]/[knob root.fps]] the problem is that I cant write it in the text message because it read the (/) as symbol and not as divider between the current frame and the fps. Then I created a user knob in the shame text node, a simple integer which was able to read the above expression and give me the result. But when I linked this knob with my message field, prints the expression and not the result.

Does anyone knows how to fix that, I will be interest to know
1. how can I use mathematical symbols as (+, -, / etc.) in the text node.
2. how can I link the result of an expression in the text node and not the expression itself.

thanks

any advise would be appreciated

Linear EXRs from RED-file – how do I work with them?

I’m playing around and testing a EXR workflow. We mostly use RED-files, and in RedcineX (or any other program that can render R3D) you have the choice the choose Linear as gamma curve. And in RedcineX you can only export with linear gamma if you choose EXR. That’s fine I guess. But, now I have a problem. As I load the files inte Nuke (or AE), I get a very dark image. My read is setup as Linear, and I look through the standard sRGB viewing LUT. Is this as it should be? If I add a colorspace node and set my out to sRGB I get a much nicer image. But that can’t be the right workflow, can it?

expression to offset roto keys?

Hi,
I have a roto with key frames from frame 10 to 20.
I want to offset them so they start at frame 30 WITHOUT using the curve editor to highlight & move them.
Is there an expression that I could add to the node to offset all the keyframes to start at frame 30?

I tried [frame] 30 but no luck

Thanks,
Lou

What is the “Value” indicator in the viewer?

Hey all,

I’m trying to figure out what the viewer indicator for "Value" is really telling me. That thing at the bottom of the viewer. It’s showing me the R, G and B values, as well as H,S,V and L. Lightness gives me the average of RGB, as it should. An RGB value of 0.5 however, returns V=0.74, while a RGB=0.21404 returns me a V=0.5.

Putting down a new Constant node with the V set to 0.5, still gives me a V=0.74 in the viewer.

From what I understand, Value is simply max(r,g,b) which in a gray-scale image would make no difference.

I’m guessing there’s some gamma:ing going on somewhere. What am I missing?

edit: oh, and I’m talking about 16-bit images, if that matters.

NukeView | Quickly open sequences with Nuke viewer on OS X. . .

NukeView is a simple app that allows you to easily open an image sequence in the Nuke viewer without going through all the steps of opening the app, creating read nodes, finding the sequence, etc. You can simply drag and drop any file in the sequence onto NukeView and it will open Nuke in viewer only mode, then begin playback of the sequence.
