How to disable a dissolve node’s input.

Does anyone know how I can disable an input on a dissolve node?

If I have 3 inputs and I want to dissolve from 0 to 2, is there a way of turning off 1 so it doesn’t effect the dissolve?

In the test script for the last 20 frames I would like turn off the green and go straight from blue to red.

Any help is appreciated.

Thanks.

Does anyone have a way to exceed Nuke’s built-in limit of 500 for the rows/columns?

Projecting beziers and doing “3D roto” question

I watched the video from the 2009 Nuke masterclass where Frank Rueter shows how he projected beziers on geometry to do roto based on a tracked camera. It looks great, but I have some issues. In the attaced project I have seutp a simple groundplane and a bezier projection. The problem is that as the camera moves, my bezier becomes heavely distorted. What would be a good way to get around this? Am I doing anything wrong?

Also, looking at the FX Guide TV episode (http://www.fxguide.com/fxguidetv.html, episode 96), an artist from MPC shows how he used "3D roto" to create masks, with something that looks like a different approch. Using the projection method, you can only have the mask line up at the projection frame, but for his method, the mask seems to track along at the right point all the time. Showed at around 7.25 into the video. Can anyone explain this technique?

FrameCycler crashes all the time

Hi guys,

It’s driving me totally crazy. Please help…

Framecycler crashes all the time when I try to flipbook it in Nuke.

It used to work in Nuke 6.0v7 and now stopped working.

I installed Nuke 6.1v3 and the same issue. Framecycler crashes.

Any ideas why?

I use Mac OSX with ATI Radeon HD 5770.

Thanks for any help or ideas.

CameraTracker always crashing

I have footage that I’m trying to track in NukeX and no matter what I do with the settings and the load, Nuke always crashes before the track completes and loses all progress.
The footage is a single 5192 frame shot and this is the only thing I can think of that may be messing it up.

If so, how would I go about splitting it up and still having a single camera at the end?

Thanks

ColourMatte node

I’m trying to roto a girl’s hair ( which is dark ), against a background ( which is light ). It’s a;most impossible to roto with the Roto node, so I’m opting for other ways to achieve this. Can someone explain the F_ColourMatte node to me, or maybe other ways of achieving this tricky roto? Is F_ColourMatte a good way to do this?

Thanks-
