Great!  Thanks to both you and Frank.  Both suggestions are very helpful to

[Nuke-users] curve expression between two points

[Michael Hodges]

I’ve used cyclic expressions for animation like:

(sin(2*pi*(frame)/24)+1)/2

And I’m also quite familiar with using the curve editor.

However, what would be the way (mathematically with an expression) to create a 
smooth transition curve from, for example value 0-1 from frame 0 to frame 100?  
 Maybe a sin wave that is held at the apogee or something?

[Nuke-users] Unwanted UI Resize handle with group/gizmo

[Michael Hodges]

I’ve got a gizmo that contains a text node in it’s internal tree.  Regardless 
of whether the text node is activate (or even connected in the tree) it always 
shows the resize handle when the parent gizmo controls are active in the GUI.  
Interestingly other nodes, including ‘transform’, do not exhibit this behavior.

 I was actually only using the text node to generate an automated error message 
(if needed) so I may, in the end, choose a different approach.  However, it 
would be nice to know if there was a way to disable it in the display or if it 
could actually be a bug.

[Nuke-users] Nuke "Python Button" callback issue

[Michael Hodges]

I’ve got a callback that affects a certain gizmo class recursively throughout a 
script:

###
def SmartReadUpdate()
allNodes = nuke.allNodes(filter='SmartRead', recurseGroups=True)

for n in allNodes:
MyCodeHere……..




I want to add a python button called “update” on each of these nodes that will 
manually force the callback if the artist wishes.

The same callback works fine if I call it from the script editor.

However, when I call it from the Python button it loads without error but does 
not execute anything.

Is there a different way that a python button behaves that would keep it from 
running the "n in allNodes” part of the script or is there something else going 
on here?


Thanks!

[Nuke-users] Update Quicktime frame range via python

[Michael Hodges]

In order to automate the replacement of a frame sequence in a read node using 
python, I simply replace the read's “file” knob and reset the frame range knobs 
by counting the files in the frame sequence (using Glob in my case).

However, if I wished to update the file with a Quicktime .Mov it will only 
update the frame range by manually selecting a .mov file in the file finder 
popup.  If I add the via python I still get stuck with the previous frame range.

Is there a better way to update the read file to simulate a new selection or, 
perhaps, a good python way to read the .mov file length from the file's 
metadata?

[Nuke-users] Good practice in Print messages.

I notice some Nuke python coding that seems to have an option to reduce 
messages (ex. print(SomethingGoingOn)   ) for running on the farm.

What is the general view on this?  In writing code, do all messages have the 
potential of disturbing farm processing or is it just good practice to keep

Re: [Nuke-users] Gizmo panel conditional changes?

[Michael Hodges]

I’ve got this working somewhat where the knob simply changes color.  
MyNode.('tile_color').setValue(0xff00)

So I’m on the right track.  Still can’t seem to find the specific reference 
knob font color.  
I see that I can set a specific knob to be visible or not using something like:

(‘MyKnob').setVisible(True)


Is there a way of changing it’s font color?

[Nuke-users] Python reading pulldown menu choice

[Michael Hodges]

Since Pulldown menus seems to be the subject of the week I thought I might jump 
in…


I can easily get a Python expression to derive a value of the selected 
(e.g.)“Option1", “Option2", etc. from a pulldown menu within nuke using a 
python expression.

[python {nuke.toNode(“MyNode").knob(‘PulldownMenu').value()}]




However, when trying to read the same Pulldown in a callback through Python I 
get the error below.  

n =MyNode
PulldownValue = n[‘PulldownMenu'].value() 



TypeError: list indices must be integers, not str



I understand that the knob contains a list (to create the options) but is there 
a way to get the resolved value as from an expression within Nuke?

[Nuke-users] Gizmo panel conditional changes?

[Michael Hodges]

I’m starting to create gizmos with more complexity.

I want to have visual indicators for the artist that signal conditions that are 
going on inside the Gizmo.

Usually a warning or a condition being true or false ( file exists, etc ).

I’ve been using a Checkbox as that seemed to be what was available through the 
user knob management.


[X]  File Exists
[  ]  File is .MOV

Obviously, that isn’t the best solution as it allows the user to monkey with 
the knob and/or expression.

Are there expressions that could conditionally change the color of fonts (or 
text value) of specific knobs in a groups parent node that would carry over 
into a gizmo?

Any other solutions or documentation I should be looking at?

Thanks,

Thanks Jake.  I’m on 10.5v1 and it doesn’t appear to be working within the

Still a bug?  Can anyone else confirm?

If so what would be the best way around this?

Thanks!

[Nuke-users] Selecting all nodes in a class

[Michael Hodges]

Is there a way to select all nodes in a class regardless of whether they are in 
a group or not?

All the examples I see are either for selecting in root or within a specific 
group.

I’d like to have a custom node (or class of nodes) that I can universally 
select/execute on within any script they reside in regardless of whether they 
are nested in groups or not.

Re: [Nuke-users] frame sequence range detection

[Michael Hodges]

I’ve begun to answer my own question and I think I’m pretty close on this.  

I’ve started to adapt a script I found from Gabor Toth (thanks Gabor!) and 
hopefully this will help others as well.

I put a python button on the read node that contains the script below which 
replaces the frame ranges correctly. 

The reason I used a button is that it was an easy way to see if it would work, 
and two, I couldn’t really figure out how to configure the command to the 
specific node on demand.



Three questions:

1.  Is a button the a good way to achieve this?  I thought it might be best to 
have it hardwired on the node as it will be buried in one or more gizmos (that 
may be created procedurally) and I didn’t trust my Python chops to isolate it 
from the other read nodes in the script


2.  Assuming that this is the best approach how would I activate the button 
press from another node?


3. Since the “file” value is generated by an expression ( in my case: [value 
Controller.ClipPath] the real path isn’t being resolved to the script and 
fails.  It does work as expected with a text path.  Would a different 
expression technique work or do I have to create some additional python magic? 



Thanks!

[Nuke-users] frame sequence range detection

[Michael Hodges]

Is there a way to detect/update the frame range of an image sequence ( 
Example_File.#.dpx) in a read node?

I’ve got some expressions that can change the input file within a gizmo read 
node but then I’m stuck with the previous file’s values.  I understand that 
this may be end up having to be a some sort of python file-counting callback 
but I want to check first if there is a way of doing it within Nuke.

[Nuke-users] auto-switch node

[Michael Hodges]

I ‘ve always use the following as an "auto switch” expression in a switch node 
that automatically picks an alternative input in case there is an issue with 
the the read node:

nuke.thisNode().hasError()

However, I’m making a group/widget that I’d like to automatically have an 
internal switch that senses whether the user chooses to manually use an input 
into the group/widget or switch to an alternative default internal path.

The issue is that if the user decides not to connect a read/input into the 
group/widget it doesn’t actually create an error the same way a bad read input 
so my “auto switch" expression doesn’t trigger.

I though about putting a node upstream that would react somehow “true” to any 
signal but couldn’t think of anything.

Does anyone have any expression ideas on how to get a switch to automatically 
choose an alternative input if the first input stream has no input?

[Nuke-users] Offset project size scale for Roto work

[Michael Hodges]

I need to merge two rather complicated legacy scripts into one nuke project for 
reasons I’d rather not go into.

One script’s project settings was UHD (3840 x 2160) and the other was created 
in 1920 x 1280.

Of course the script that was created in 1920x1280 has all of it’s roto curves 
and scalings all misaligned within the new UHD Project.  Is there a good 
approach to offset roto curves and transformations values to match a new global 
scale in order to realign or am I totally screwed?  I was really hoping that an 
axis type node could scale it all up or down uniformly.

[Nuke-users] ffmpeg loaded for NukeStudio comps?

I noticed that in my Nuke Studio comp project settings it (by default) adds 
OnScriptLoad: 

if nuke.env[‘LINUX’]:  nuke.tcl(‘load ffmpegReader’)  nuke.tcl(‘load 
ffmpegWriter’)  else:  nuke.tcl(‘load movReader’)  nuke.tcl(‘load movWriter’)




Is this simply how Linux handles .mov files or is there something else going on

If so I'd love to see an example.

I know ffmpeg has a lot of options so I’m a little unsure where to go past the

Re: [Nuke-users] Nuke Studio : Windows and QT

[Michael Hodges]

I’m interested in automating Quicktime to dpx/jpeg sequences for Nuke/Nuke 
studio through FFmpeg as a pre-edit step during ingestion.  Is there anything 
in particular ( besides file sizes, color settings) that I should be aware of 
to keep Nuke happy and the files as close to native as possible?

Re: [Nuke-users] Removing errors from tree

[Michael Hodges]

Thanks!


Actually, it’s just a gizmo that has multiple 'Read' nodes in it that pull 
graphic files in from different folders based on the environment.


The only errors that I have are the read nodes.

It has some switches to that switch to alternate sources automatically if they 
detect upstream errors.

The only problem is that I can't get those errors to carry over to the group 
node.

Wasn’t sure if there might be a python command to ignore an error on a 
particular node.

Any thoughts?

[Nuke-users] FFmpeg commands from within Nuke

[Michael Hodges]

I’m creating a series of automation tasks using Nuke to append a series of 
image sequence clips (along with some predetermined image manipulations) whose 
sources may change depending on the artist's environment.

These would automatically be written out on the farm and processed for review.

The only issue is that some of the clips may have corresponding .wav audio 
which can’t be written out within nuke for the final render.


My solution is to offset any pre-existing audio .wavs (located in the Read 
paths with the same base name as the image sequences) by the corresponding 
Append lastFrame count and then run a ffMpeg render-time callback to merge 
those wavs (based on the offsets and descriptions generated by the script) to a 
new file that is read by the farm



Before I start from scratch I thought I’d see if there were any existing FFmpeg 
nodes/gizmos/code out there that assists with FFmpeg manipulation or writes 
within Nuke.  I didn’t see anything on Nukepedia but I figured that it would be 
good to check here first.___

[Nuke-users] Adding Python Packages

[Michael Hodges]

I want to allow the creation and reading of QR codes within Nuke (Think for 
reading camera slates, asset tracking, metedata, integration, environments 
setups, etc.)

I think this is easily possible with python tools like qrtools and pyqrcode.  
https://pypi.python.org/pypi/PyQRCode 


Example code:

import pyqrcode
qr = pyqrcode.create(“TEST TEXT.”)
qr.png(“test.png", scale=6)
import qrtools
qr = qrtools.QR()
qr.decode(“test.png")
True
print qr.data
TEST TEXT.

However, my only experience with python has been to manipulate data within Nuke 
and Houdini and I confess I’m a little fuzzy on how to actually add a package 
and I can’t seem to find much info on it.


How do you do this?

Thanks!

[Nuke-users] Nuke Studio interpreting file path ENVs.

[Michael Hodges]

I’ve got custom ENV paths (ex:  os.environ["JOB”]   ) in all read and write 
nodes throughout the Nuke workflow.  

In a Nuke Studio timeline these .nk scripts work fine.   However, Nuke Studio 
cannot reference through to the rendered files for playback as it obviously 
can’t interpret the path. 

The write node could end up describing something like:

$env(JOB)/renders/movie_v01..dpx

or 

[python {os.environ[‘JOB’]}]/renders/movie_v01..dpx


I could fix the issue with a Nuke render-time callback to create an absolute 
write path but for flexibility I’d really like Nuke Studio to have the ability 
to interpret the path (os.path environment) properly.

However, due to the written syntax I can’t figure out how to set a environ 
variables for Hiero/Nuke Studio to reinterpret the path correctly.

Any ideas?


Michael 



PS As a side note I did discover that Nuke Studio derives the rendered file 
paths not from the write nodes themselves but from the the " #write_info" 
description on the second line of the nuke script.

I’ve been fighting with this as well.  I understand that due to the nature of

[Nuke-users] Simple Custom Environment Variable setup

I know it’s kind of a basic question ( I already asked on the forum and the 
silence was deafening) but I’m struggling with properly setting up

a custom environment variable in Nuke.  I’ve read the documentation but it 
seems to gloss over the fundamental set up a little.



So I've got two questions:

1.Assuming my variable would be something like "NUKE_JOB" ( like Houdini) and 
my resolving path would be /path/to/job/ ... What would be the syntax to add to 
my init.py.?


os.environ['JOB'] = '/path/to/job/‘ 


2. Would I then simply call NUKE_JOB in the Nuke file dialog with:


 [getenv NUKE_JOB]/render/

Re: [Nuke-users] Nuke Studio Performance

[Michael Hodges]

Personally, I've never been clear on how it uses memory.  It seems like 
it might create another instance of the settings' memory allocation when 
you initiate a render so I've always capped memory at half of what I 
have available so as not to max it out.  Of course my theory may not be 
correct and the numbers didn't always match my predictions in that regard.

Right, I think I will have to live with it as is for the mean time then!

Just a note on your comments about memory. This morning the project 
was roughly 40GB of ram, above what it should be limited to in 
preferences. After creating a couple more comps and a couple of 
renders it had climbed to 63.5GB, a hair below what the machine has 
physically available. So something bad is happening inside NS's memory 
management.


Lord knows why it needs all of that.

Don't get rid of the clips, just don't conform them. If you need to

Sadly there's no real "unconform" shot in nS, nor a plug for it. 
There's a few "make offline" stuffs on nukepedia but they don't reset 
all info to the unconformed state of a clip so it's a compromise that 
works for some peeps. =(


I'll raise your 20 emails with my constant nagging about this to both 
support and devs since 2012. =/ A quick solution, or any solution at 
all, feels distant. =/ I've honestly more or less given up and have 
taken an unofficial decision that Nuke Studio won't be in our next 
pipe. Instead of spending our time fighting bugs and stuffs like you

in making something more custom where nS isn't the hub. =(

At the moment I have Studio running on a dedicated machine which is

while all the other machines run Nuke.


I could get rid of all the clips in between the VFX shots but it's 
likely we will be asked to pick up shots that have been removed 
which would be a bit of a headache (and frankly I shouldn't have to 
resort to this).


The Centos idea is interesting. I may ask one of our engineers to 
give that a go in the new year and see how it performs.


I have emailed support about this a couple of days ago but have yet

Yes. We use it, or rather try to use it, for long form and 45-60 
min episodicals. The quicker you accept that it's not usable for 
this the better of you are. Sadly. They say that nS10 will improve 
this enormously but today it's a disaster. It's been like this for 
day one and I and others have loudly complained but without luck so 
far. Please send your experience to support so they can log it and 
so that these issues are up voted.


Some people have resorted to work in reels instead of whole 
timelines. That's not something I'll ever do though. Wouldn't fit 
my working style and would only mean. I would have 4 projects open 
at the same time, which wouldn't help.


A few of my "workarounds":
* only conform the VFX shots. Never conform the whole timeline. If 
needed for review, conform a few shots before and after VFX.


* never copy all cuts to the reference media. We export reference 
into our comps but we only slice up the parts where there's VFX 
shots. NS chokes with many cuts/items. Also play with different 
formats of your reference. Noticed that codec of your reference and 
also the codec of the audio in it can affect performance a lot. Not 
sure what's the best though. If you find out, let me know. =)


* save a lot because it crashes a lot.

* also, even though it can take a good 10 minutes to restart it... 
Do it regularly since a restart of it normally tends to give you 
30-40 mins of less lockups, until it have leaked and filled your 
memory again.


* if there's something like 'Sudu purge' or other memory purge 
solution for Windows, try that. Monitor your memory and see how 
it's used. Even with 128 GB RAM it will eventually come to a halt 
but it'll give you a few more minutes at least.


Also, have a few spare keyboards handy. Have out of frustration 
hulk smashed a few myself. The marketing of nS doesn't really 
reflect the reality of it atm. =/

Re: [Nuke-users] Nuke Studio Performance

[Michael Hodges]

Over the past year I've used it in Mac OSX, Windows 7, Centos6 and Centos 7

I didn't have alot of luck until I built a dedicated workstation for it 
on Centos 6.7.  It still isn't happy bringing in older projects, as they 
seem to retain their gremlins, but it's certainly more snappy, solid and 
finally enjoyable to work with.  Also 9.0v8 seems to be a slight 
improvement.


I can't say exactly what it's happy with or if I'm just lucky but it's 
certainly getting better with each release and I certainly hope that 
trend continues.


I seem to remember that thread usage made a big difference.  I have my 
threads limited to 12 which ironically got rid of some sluggishness.  
That issue may have been addressed.



Just my 2cents and I'm not necessarily suggesting anyone run to Linux as 
the Foundry has a few issues they need to address with Quicktime and 
audio first.

Do you have any soft effects applied? They are WAY slower applied per

Is anyone out there having terrible performance issues with Nuke 
Studio when in the timeline?


I have done a conform on a show roughly 90 minutes in length and am 
going through shots preparing notes, making comps, tagging, setting 
reference media etc and every 1-2 minutes I'm getting about a 30 
second lockup. Just now after I had left the workstation untouched for 
an hour I selected a shot and added a note and it locked up for a 
minute while I was typing it out.


I've noticed creating a comp from a clip can take an extended period 
of time (many minutes) while a single core on the PC is at 100% with 
the other 23 sitting idle.


Is there anyone successfully using Nuke Studio for long form? I had 
engineers from the Foundry visit a while ago looking at lookups when 
creating comps but I never heard back from them. Disabling shot 
thumbnails hasn't made any difference. There is no way anyone can work 
like this for any length of time!

Re: [Nuke-users] Frame offset in Nuke Studio

[Michael Hodges]

I encountered something similar on Linux once.  It may be unrelated as 
it was a pretty messed up reconstruction of an old project already but I 
thought it worth mentioning.  URSA Prores if I recall.

Pretty much the only time I'm doing any sort of vfx conform I'm 
dealing with prores files, never image sequences. I think the times I 
needed to fix I manually fudged the frame ranges in the comp and 
brought in the dpx sequence and lined it up.

Thanks Charlie, glad to hear i’m not the only one experiencing this :)
I’d like to dig deeper into this issue but at first sight it looks 
like something related to Prores or OS compatibility. Have you ever 
encountered this problem with images sequences instead?

CAUTION EXTERNAL EMAIL



Hello Everyone,

I’m running into a strange behaviour : I got a QT prores  file 
from editorial and rebuilt the various cuts inside Nuke Studio (OS 
X), when i build the track and export the comp for the artists to 
work on (Nuke Windows), all the shots are slided by 1 frame, 
removing them the first of the shot and giving the first frame of 
the next shot as last… Then they save it on their end, I refresh 
the timeline, the edit points remain untouched but there’s clearly 
a problem of frame range interpretation in the nuke comps and it 
messes with everything (roto is offseted & so on…).


Is this a known issue between OS X & windows ? Am i doing something 
wrong when exporting the vfx structure ?


Best regards,

[Nuke-users] Linux NukeStudio with Decklink

[Dan Michael Hodges]

I've finally set up our shiny Nuke Studio suite (nuke v9.8 / Centos 6.5 / 
Decklink 4k 10.5/ Boxx workstation).  I'm putting it through its paces this 
week and am noticing that Decklink seems to need a "kick" every once and awhile 
to output either the correct framerate, sound or both.  Once dialed in it seems 
pretty stable until switching to another program,  switch to another .hrox etc.

"Kicking" usually involves switching back and forth between 8/10bit,  switching 
monitoring off then back on or (at worst) reboot. 
Is this approximate to other Linux user's experiences with Decklink + Nuke or 
is this an indication of something 
wrong?___

Re: [Nuke-users] Blackmagic film

I'm also very interested in a streamlined approach to the BM RAW URSA footage.  
I'd love to avoid an extra step in Resolve as well.

 You can use Resolve to transcode the dngs to for example a linear gamma. 
 Resolve also ships with a BMDFilm to linear lut (1D) thay can be used in 
 Nuke as a ColorLookup.
 
 As for the primaries, there's no way to convert those into a known 
 colorspace (as far as I know). As a workaround, I think you could use 
 Resolve to output ACES exrs and then convert those into a colorspace of your 
 liking.

Re: [Nuke-users] Nukestudio Picture in picture

[Dan Michael Hodges]

I don't think so.  They are working on a layered option in the timeline to be 
released later(hopefully sooner) that will be a huge step forward in usability 
for Nuke Studio.  I had a lot of fun (sarcasm) recently doing DVE type 
multi-image wipes in nuke for a Nuke Studio edit.  I should of just migrated 
the project somewhere else but I was pretty determined to stay in the Nuke 
Studio environment.

 Is there a way of doing a basic picture in picture in NukeStudio without 
 going into Nuke.
 
 I just wanted to do a basic comparison - image scale 0.5 and shoved left, 
 layer below same but shoved right.
 When I did this using the timeline effects, I couldn’t see the layer below. 
 
 So I had to go via Nuke to do this basic function that all other editing 
 software does.
 
 This is 9.03 - what am I missing?

Re: [Nuke-users] nuke studio nested timelines

[Dan Michael Hodges]

Doesn't look like you can nest any sort of sequence inside other sequences at 
the moment.  There may however be some potential work arounds (as there is a 
lot of clever customization potential) but it wouldn't be straight forward 
right now.

Nuke Studio is really starting to grow on me. With a few more features 
(hopefully this year) I could really see myself doing all editorial through it.

By the way.  Glad to see this mailing list still working.

Re: [Nuke-users] Deep reading Read node

[Michael Hodges]

Yeah, I figure it wasn’t keeping all the Deep Data.  However, it really fooled 
me because the renders were coming out of a legacy Project that we were 
re-rendering in Deep and accidentally still had a traditional Zdepth 
pass/channel embedded.   They really behaved JUST like a traditional EXR with 
the ZDefocus node.  

I just assumed that it was only a normal EXR and actually spent an hour trying 
to figure out why Arnold wasn’t rendering Deeps correctly on the farm:)

Regardless, it’s nice that we can do quick and dirty comps with the normal read 
node.  Should of noticed that earlier.

Michael
