Hasta La Motion!

Hello everyone.

I’m sure this is a really stupid question, with a really simple answer, but it’s been driving me mad.

I’ve got 1 viewer node connected to 2 read nodes via pipes 1 and 2. If I look at pipe 1 and zoom it from 1x to 6x, then switch to pipe 2, it has also zoomed in from 1x to 6x. Also, if I move around while looking at pipe 1, I find that pipe 2 has also moved.

What I’d like to do is to be able to freely zoom and move around pipe 1 without affecting pipe 2.

Is this possible? I’ve looked through all the setting and preferences but can’t find anything.

Many thanks.

Hi there,

I´m sorry if this is a repeated topic, i´m actually in a real hurry!. I´ve got to composite greenscreen plates and i´m actually getting unable to achieve decent results. I have lots of artifacts (and apreciable compression patterns) everywhere and some parts of my plates are blurred or show some ghosting. Neither Keylight nor Ultimatte or Primatte seem to deal well with this issue, and i´m pretty a newbie aswell to re-programe these plugins..

¿Is there over there any trick or something to deal with this kind of disaster?

¡¡I´d appreciate any help you can give me!!

Thanks a lot

Hi, i’m wondering if anyone can explain to me how the depth channel is calculating from 3d scene in nuke. It’s kind a weird, i did some test using a 3d card. I found that the relationship between the distance (from camera to object/card) and the output depth value is not linear. Here are the data of distance – depth pair (first column is distance, second is depth alue) :

0.1 – 10
0.5 – 2
1 – 1
15 – 0.06
30 – 0.03
60 – 0.016

the conclusion , within the distance range of 0.1 – 1, the relationship is not linear, kind like an ‘exponential’ ? but it’s start to linear start from distance of 1. So i’m wondering how they’ve ben calculated. Don’t you think it should be linear all the way from 0 – unlimited. also can someone explain why the closest depth value is 10 ?

As comparison i checked the way Houdini output depth z channel, which is exactly linear to the distance itself (not only linear, but the distance and depth even share the same value). So let say if i want to work with image rendered out from Houdini, i can zmerge with FG which is i created using nuke 3d, by placing obj in nuke 3dspace at exact 3d distance (this is why i need to have linear depth from nuke, so the two can match in 3d space) . I just want to try this way , which is ussually done by grading the depth channel manually.

thanx

hi guys,
I got admission in Leeds Metropolitan university for MSc Animation and Visual Effects. I want to know you people opinion on it about the standards of the course

Thank you guys
