Hasta La Motion!

(i know i need set rotation order, and translation order, but i do not get a logic behind that)
some body can make small explanation:(

pls dont send me to manual

I’m in the process of getting more advanced with nuke and would like to ask a couple of questions that may get you thinking even if you’re really used to working with nuke.

I’d like to hear anyone’s answer,

I know that when you work in nuke it’s necessary to sometimes premultiply/unpremultipy.

I know that this is necessary when you need to use the over operator.
I also know that it’s recommended to unpremultiply/premultiply for color correcting.

correct me if I’m wrong

While using the channel nodes such as shuffle-copy, channel merge, do these premultiply the image or should you do a premultiply before/after merging channels or shuffling them around from different sources?

For example, you get the r,g and b channels from different sources and then copy in the alpha from another source.

Would the alpha be premultiplied at this point with the r,g, b if you had done a premult furthur up in the stream or should you do it after the merge or shuffle?

ok this still kicking, especially due to it being a very simple thing plus I did have this working.

ok what I am trying to do is use a bezier to section out my key into areas like hair and other areas that need special attention.

I see it done in fxPHD tuts (not explained but shown the result) and it work for on a couple of keys.

I have attached a script (this is the way it was layed out in the tut and how I "had it" working) where it does not work, you will see that I have created a channel for the mask / bezier.

if some one could point to were my stupidity kicks in..

on the brighter side I have other ways to do this but this is far more elegant.

cheers

I’m using 4:1:1 footage from miniDV.

Would anyone know of a good operator in nuke to remove what they call "DV artifacts"?

In After Effects I used the Median effects.

I’m not sure what this would be in Nuke.
