Simple question from a X-Fusion artist regarding merge.

Ok, super simple here.
I got 4 images (3 pictures and 1 render with a alpha chanal.)
In fusion if i wanted to show them off side by side and have the render on top all i would do is merge them together and mask for my needs.

If i do the exact same thing in nuke with a "over" merge the images does a screen or average instead.

For a moment i though addmix would do the job but i can seem to get the masking working for that one.

How can i do a merge in nuke where i can put a foreground over a background while still being able to mask, just like a regular merge in fusion.

Here is a little screenshot of my problem, where left is the nuke setup and right is the intended result in fusion:

unrecognized opengl version and setup advice

Hello, I have searched and found some suggestions but I cant sort out getting "unrecognized opengl version" at startup in the console window, I am using a GTS450 Card, Is this impacting my speed the opengl warning? Nuke runs fairly slow and does crash fairly often.

My specs are Core I7-2600, 8GB Ram,GTS 450,Win7 on SSD, 30GB Nuke Cache and OS swap file on separate SSD, 1TB Raid 0 storage.

What would my best upgrade be here to improve performance? I do light weight stuff.. Just use the furnace plugins and some camera tracking.

I have a q6600, 4gb ram machine lying around, could I utilise this in some way to speed up rendering?

Cheers

Parenting file paths?

I’m making a gizmo, and I need 3 different text nodes (same font) displayed at once. It’s pretty annoying to have to enter the same file path 3 times, so is there any way to parent the file paths to each other?
Thanks 🙂

Advice on Nuke to Editor worflow

Hello artists,

Im a CG artist, taking up videography as a hobby. I purchased the nikon d7000 and need a way to move h264 footage in between my editor and nuke.

If anyone does similar work, what is the general workflow?

Nuke/Ocula Fixing Stereo w/ roto

Hey guys

I am having problems with using the interaxial shifter. When applied, it obviously generates some artifact or tearing of the image. This is understandable. My question is how exactly do you go about fixing the areas that have these artifacts?

I tried rotoing back in pieces from the original stereo pair before the shifter was applied but it becomes more of a jumbled mess than before. I’m obviously doing something wrong. I know some kind of roto will be necessary I’m just not sure what to do with it once I have the original pieces rotoed and where to put those pieces in the tree.

Any help will be greatly appreciated. Thanks

James

Does multiple reads of the same thing slow down renders?

Hey guys,

Quick question. If I have some footage that I’m using in a bunch of nodes, does it make a difference if I read it multiple times and use them them where I need them as opposed to taking multiple outputs from only one read node of the footage as far as render times are concerned?

Does Nuke know that its the same footage or does it actually re read the files each time theres a read node?

I’m assuming it re reads it each time and slows it down, but I’m just checking.

Thanks!

It’s a very interesting technique that is widely used now days.

Anyone with pointers on how to do it in Nuke
Thanks

convert 29.97 interlaced to 24 progresive workflow

Hi, i’m working on xdcam hd422 1080i60, res 1920×1080 interlaced , the original rate is 29.97fps (rushes), it’s edited on FCP, and at the end will be transfer to film (non interlaced @24 fps) . So overall workflow will be converting from 1920×1080 @29.97fps interlaced to 1920×1080 @24fps progressive. The FX Compositing in-between that workflow will be done in Nuke.

The normal workflow is : from fcp 29.97fps, go to nuke @29.97 too, do the fx then send back to fcp @29.97, finally convert to dpx @24fps. How about converting 29.97 to 24 inside Nuke then do the effect @24fps so i will have fewer frames to work on , for example : rotoscoping 1 sec will have about 5 frames difference between these 29.97 and 24. Is it a good idea to do converting inside Nuke? also the footage is interlaced so i need to separate the fields. Any suggestion ? Does Nuke have good tools to deal with this conversion ( i found couple of plugins/tool , like fiedskit by Diogo etc) or need to do it outside Nuke ? i didn’t hear any good before version 6. Or any better workflow? there will be no change in resolution (HD 1920×1080), the blow up to film res will be done outside this workflow (optical) so no need to worry about it.

Thanx a lot.
