Hasta La Motion!

Greetings guys,
I’m new to the nuke ndk and I’m trying to figure out how to make my operator plugin access other layers/channels coming in from a single exrReader node.
for example, i have a single exr file that contains multiple render passes that i’ve rendered out via maya and if you looked at the the exr’s channel list through a shuffle node in nuke you would see the typical rgb, rgba, alpha, and then pass1, pass2, pass3, etc… the extra layers also show up under "other layers" in nukes channel lists as well. so im trying to figure out how to access those other layers/channel in my operator code and have not found any examples or useful information in the ndk docs related to that specifically and was wondering if anyone here knows how to do that in c++. I haven’t found any find channel by name type functions either, I’m guessing the the nuke design is to keep it as node based as possible, but i need to be able to access all of the different pass layers from a single plugin/node, instead of having to set up shuffle nodes to select each layer that i need. Any help would be much appreciated or even some code to show how to list the names of all the channels/layers coming from the single exrReader node and how to read data from those channels in my engine() function. Any advice is much appreciated.

Hey guys!

Today I succeded with my shot.
Atleast as far as I know.

I have posted some questions before in this thread:
http://www.vfxtalk.com/forum/pftrack…tml#post141033

Anyway people requested me to upload pictures for them to help me. Now I have a pretty good track but to learn more I thought Id just ask you guys what type of worklflow you would apply to the specific shoot.

Camera: RED ONE
Lens: Tokina 11 – 16mm
Feature tracks: 10
Autotracks: 575
FPS: 120
Frames: 1600
Size: 2048 x 1024
Type: tiff sequence

It was filmed with a steadicam rig and the operator is running through the scene but since it is 120 fps it is a pretty long shot. In the beginning it is quite blury so that is where most of my problems lye.
The camera enters the room in an arc and then pans through the room focusing on the table.

I started by doing an auto track in the middle where there are loads of good tracking points. The red parts in the images ar approximations of my masks that were used to get rid of bad areas.
After auto tracking I solved the middle are and extended on by more auto tracks. Then I deleted bad points and added my user tracks and improved the solution. Still my solution wasnt good enough so I used the clean features thing and deleted some more points and created 5 different constraints. Then improved the solution again.

The result is a good but not exellent track with a camera error of RMSE 0.416 pixels and Inlier RMSE 0.378 pixels.

Now this is one of the first times I am tracking so I have learned alot but still have loads of questions.

Is this a good error result considering the size of the footage?
Is my workflow good?
If not how would you approach the shot?

My main problem right now though is that the file that I export to maya has ALOT of gliding. Something that isnt apperant at all in PFT.
Do I have to set up maya in a special way?

Hi, I’m new in nuke and I want to know how to convert the frame rate of footage?
Thanks

Have a look at this video..Some great VFX 3D and Animations
