R3D Footage and Noise

Hi, I have some R3D footage that was shot and I started to color correct and I noticed that there was a lot of noise in the blacks(Shadows). I asked around and found out that, that is quite common with R3D footage. So I was wondering is there anything I can do to reduce the noise? The footage was shot at night in a warehouse so it’s already dark. Any help would be great.

Thanks

Downgrade the Roto Paint node to original Bezier

So, as i’ve learned from another thread, I can access the old bezier node when I need (thank god), but lets say I ended up using the new roto paint node for some roto, and then go somewhere where the studio doesn’t have the most recent version of nuke (like Nuke 5.2v3 or whatever). Is there a way to convert the roto points from the roto/paint node back into an original bezier node?

Pop-up Browser

I’m looking into creating a cross-app utility which would just be a hosted website. Would it be possible to pop-up a dialog with a web browser in it pointed to a URL?

It’s possible with .net through the WebBrowser Control (http://msdn.microsoft.com/en-us/libr…(v=VS.85).aspx). Is there any such PyQt control that ships with Nuke?

I haven’t really dug into Nuke 6 UIs yet so I’m not entirely sure what all is possible. Is it easier to write a PyQt dialog in Nuke 6 than it was in Nuke 5?

Any pointers in the right direction would be really helpful.

Accessing child nodes of a gizmo with python

Hi guys!

I can’t manage to get the child nodes from a gizmo… actually it’s quite simple, if I create a group in the graph, and I get it via a toNode or selectedNode method, I get a "Group" object (which is a subclass of "Node") and so I can access all its child nodes via the "nodes" method…
the problem is that when I try to do that with a gizmo, I though it would return a "Gizmo" object (defined as a subclass of "Group" and "Node" in help files) but instead it returns a Node object, whiche hasn’t any "nodes" property.

Actually I’m trying to execute some script via a "knobchanged" callback on a gizmo, so as defined in help, you can access the gizmo with the "thisNode" method, but I can’t find a way to access its inside nodes (I want to use a "sample" function on a precise node inside the gizmo)
Any clues ?
thanks,

Paul.

Change size of shapes tree in rotopaint panel

Hi

I was wondering if there is a way to resize the shapes tree in the rotopaint panel to see more shapes at a time if it is a long list. Maybe there is a way to access it through python and then change its size?

Thanks 🙂

Import multiple 2D tracks as transform nodes

Hi everyone!

I’m facing this problem: I have hundred of 2D points created in other tracking package and I need to import them to Nuke to aid with roto – probably as Transform nodes.

To be clear: I don’t mean any 3D pointcloud or any camera track. I’m talking about pure 2D tracks.

I can export them out of my tracking package in any way you can imagine, so exporting is not a problem.

Problem is how to get this to Nuke without manually creating 100 Transform nodes and manually importing ascii text files into them one at a time.

I guess it will need creating a python script that goes through text file with all my 2D tracks (formatted in example like Track1 framenumber Xpoxition Yposition), creates Transform nodes for all trackers and copies the XY position information to them…

Any suggestions on what to use as a starting point? I actually can’t do any python for Nuke at all so I will have to find someone to do it for me 🙁

Somebody got any other ideas? Some alternative approach?
Somebody willing to help please?

Thanks very very much guys.

Pan n Tile with Lens Distortion and Diagnal fisheye lenses.

Hey..

wanted to know how to do a pan n tile setup with lenses that have high barrel distortions or with diagonal fisheye lenses on full frame SLR cameras.

the lenses i have problems with
A) 14mm full frame : http://www.kenrockwell.com/nikon/1428.htm
B) 15mm fisheye fullframe : http://www.momentcorp.com/review/sig_15mm.html

it would be great if someone who uses this kind of lenses can give me tips or direct me towards some article that shows how to correct for lens distortions.

my final goal is to generate of lat-long map of the panarama for the cg team. at the moment im using a pfgui but am not satisfied with the manual options this software gives. so, wanna try in nuke to see if this is better..

thankx again.
