Hasta La Motion!

I want to influence a fade node to flicker slightly. I am trying to write an expression for my CC node gain that will generate this by randomly setting the value between 0.8 to 1.3

I hope this is clear.

Thanks in advance…:):)

So I have a plate that is 4480×1920, and I try to comp in an image that is 2240×960. It is to be comped in the background & out of focus, distorted etc, and subject to the larger image’s alpha. Easy enough.

But, I attach both images to a Merge(over) node and find that the image area now only displays a small part of the 2240×1920 image, it’s like the image is cropped to the size of the smaller image. I try to set the Merge node to accept metadata from the larger image (which is input A), but I don’t see any effect.

It’s this kind of annoyance that’s making it difficult to "simply work" as I did in Shake. Reading the Nuke documentation seems to imply that I’m already doing what I need to, but obviously I’m not. Anyone know what I’m talking about and have any common knowledge to impart? 🙂

Kindest regards

I’ve made some stationary particle ‘strings’ and trying to a get variation in the depth of field through the shot using Zblur.

Testing Zblur on a card rotated 45 degrees through the scene is giving me a nice gradual blur around the focal point … but all my particles seem to be blurring by the the same amount from from-to-back / start-finish.

The particles do actually have depth in 3D space, but I’m not sure if I’m actually getting depth information from them to ZBlur. Apologies if this is a dumb question, still new to Nuke 6.3’s particle system.

After a long wait it’s finally here… 🙂

hi all,

again, i’v scoured the forums and the internet and can’t seem to find an answer to my most simple of questions.

i have footage that i tracked in pftrack, then created a nuke python script via the pftrack export.

my question is, what the heck do i do with that in nuke? i go to my read node and bring in the .py file, but then what? how does the tree look? is a merge node used? do i have to setup a camera first? im completely at a loss as to how these my .mov clip and .py track combine together.
