question about over operator for images with no alpha/matte channel

Hi,

I’m new to Nuke but pretty familiar with the capabilities of the program.

I’m trying to learn the merge operations, starting with the Merge(over).

I understand that this operator expects a premultiplied image that is, correct me if I’m wrong, an image with an alpha channel integrated with the file.

Image A 400×400 pixels a picture of a happy face
Image B 400×400 pixels the Nuke Checkerboard

So OK, Image A has NO transparency, you can’t see through it.
I put a transform and translated Image A out of the frame ( I moved it over) and with the merge you can now see the checkerboard under it.

What I want to do is add an alpha channel to Image A to make it a premultiplied image.

Could anyone help me figure this out?

Notice how the checkerboard underneath shows through a little but with the transform it doesn’t show through the image itself, only around the sides where it was moved. Could anyone explain why that is?

FXguide TV #48 – Nuke Demo on Mummy

Hello…

I wanted to share a video that features a demo about 3D / UV / Facial Expression stuff that we used here at DD on the Mummy: Tomb of the Dragon Emperor in NUKE5. Interview was taken while I was back home at IBC’08 in Amsterdam. Its the same, but more fleshed out, demo that I did at the Nuke User Group Meeting at Siggraph. Its the second part in the vid.

Hopefully you guys enjoy!

read node workflow

I’ve noticed that the read node in Nuke doesn’t give much info regarding what’s going on with the plate being read in. Maybe there is more info there and I’m just missing it but it appears that there is no hint as to whether a plate is pre-multiplied or divided (unpremult) coming in.. I mean, I suppose you could look at the matte-edge and look for aliasing but this seems combersome.

Would it be safe to assume that a good workflow would be to go READ -> REFORMAT -> UNPREMULT -> COLOR CORRECT -> PREMULT and so on…?

Thanks in advance
