Hi. I'm Anthony! I'm one of those randomly scattered Australians around the place, they've outposted me here in Montréal for some reason, and i thought i'd you know start making videos about python/nuke recently for the heck of it. Usual stalking links below if you wanted to know more.
1x01 - Python for (Nuke) Compers - Single quotes vs double quotes (really, it's a thing)
It's like Taylor Ramos & Tony Zhou over ruclips.net/user/everyframeapainting - I'm back (in a small dose! Unsure for quite how long but it's been bubbling away to do more explain-y train-y teach-y stuff.
The TL;DR - use triple double quotes. It's good for your sanity, and keeps you in line with PEP 257 ( peps.python.org/pep-0257 )
More write up here: www.greenworm.net/2024/11/01/nuke_python_single_quotedocstrings.html
(Don't mind the 1x increment, felt like it was time to create a new "season" as it were)

Anthony Explains: how a keyswitch matrix layout works
Просмотров 20610 месяцев назад
So a friend was getting into making a keyboard (joystick button box actually) down at the hardware level, and was wondering about wiring and how it copes with multiple keypresses at once. That sorta touches on both how a keyswitch scan matrix works _and_ why we shove in diodes. - we use a matrix because the rate of humans typing is a much slower than the rate at which we can scan keys, so no ne...

AMIGO SE VE EPICARDOOOOOO, TAN SOLO CON ESTE CAPITULO YA SE NOTA QUE ES GOOOOOOOOOOD EPICARDO PAPU!!!!!
uhh a little bit of a silly question maybe but, is this tailored towards people who already know Python? or people who doesn't know anything about python at all. Thank you!
Not a silly question at all! Back when i started these I was focusing more on general concepts in the context of nuke - I was assuming that people would have some basic python so I don't think i cover very well (at all) core things like python's syntax and what I think of as "housekeeping" like modules, classes, and things like that. Unfortunately I don't know what it feels like to not know python anymore (if that makes any sense) - if you have a poke at the first two vids and it's completely "WTaF is going on??!" could you see if you can explain what you're missing? It might be time for me to carve something up that'll try take someone from the don't know anything about python _at all_ level and that could give me some hints at what i should target.
Ah a fellow montrealer!
There's dozens of us, dozens i say! (well, okay, more than dozens :D)
Please help i got syntax error
thanks for the tutorial, but i was searching if there's any way to change the color of the button, not the label
Oh this series is gold!
Watching the whole series. Day by day i am exploring nuke in more depth. Thanks for the valuable information.
hey Anthony, thanks for creating such great videos, is it possible to create a more useful, touchable, and less technical tutorial for those who do not have any ideas about stuff behind the scene?
When you say less technical, what kind of level were you imagining? There's a threshold at which things sort of break down, but since my brain is wired to think in code my assumption of what a 'minimum' level of technical might be a bit higher than is really necessary XD
@@tanantish hey thanks for reaching out, I am sure you have been at great studios, if it's possible creat some tutorials on the pipeline these studios are specializing for themselves, they use python and I think I need to see python in actual real world, thanks again
heeey Anthony, thanks for such perfect videos, I have been digging since here and I am sure you have been to big studios, can you create a more practical tutorial on what studios are doing? like minor and major versioning, also scale your videos a bit, I am testing and watching on a laptop, and the screen is not so big, thanks again
Thank you so much for the video, I just didn't know where to start and this really helps
cool!
Thanks! so good videos
Thank you! This helped me with trying to do stuff to nodes within backdrops and such and it worked :D
Is there a way to add the callback locally, seems like the callback in nuke in the company I work for is reverted every new instance of nuke
Depends on how it's set up, you could pop something in your personal .nuke init/menu.py that'd run - it theoretically is the last thing so it could override stuff but if your facility has some general setup it might not be wise to fight it as there's likely reasons (we had callbacks to ensure things worked on farm properly, or when things got shipped to farm one of the things inaccessible might be a user's home folder). If there's a local TD you can poke, they might be able to shed some light on why things are the way they are and give you an idea of what's safe to do locally.
Thanks for making this, this is very helpful
dude you rule
damn thank you so much for doing this series, it has helped me a great deal in getting started on this topic:)
# Result: Traceback (most recent call last): File "<string>", line 1, in <module> TypeError: 'str' object is not callable getting this error on typing = "the_node = nuke.selectedNode()"
Thanks for all these tutorials Anthony, really appreciate it! :)
Hi man, great videos, very helpful, thanks a lot. 1 question: how would you make it to be able to go to the topNode but instead of always follow the b stream or input 0, to follow the active input in a switch, if there is one on the way. thanks again!
If you want to give it a shot in python, the main change is the logic about where to go - instead of always going this_node.input(0) you would need to insert some picker logic. For active input, it'd be something like this (in pseudocode) if this_node.class(Switch): the_input_to_follow = this_node.input(this_node.knob(which).value()) else: the_input_to_follow = this_node.input(0) That same logic could force it to always walk down say, a mask input if there is one, or do all sorts of other fancy things.
@@tanantish hey Anthony, thanks a lot, and thanks for the videos, you are doing a big service here, cheers!
Watched all videos in 2 days. Awesome tutorials . Can't believe it is free !
12:00 I think it s better to use "finally" instead of "except" you want to exit the group no matter if there s error
Yep, you're right there - "finally" will always be called no matter what so if there's things that must be done that's the right place for them, while "except" would be where you stash the 'oh no, it broke?' code :D
Hey, Anthony Loved your content. Your Content helped me gain a lot of experience. Would love an additional series where you end up teaching how to create a particular pipeline tool that is commonly used or something in that realm. Your way of explaining is a gem
Thank You So much . Such Great Content
Hi Anthony, thanks for your sharing, it's so amazing and helpful. I'm also a passionate compositor and I have started learning Python for Comp for one month. Could I have your contact (like Facebook, Discord, Telegram, etc) and ask some questions I meet in my learning process. Hope you could reply me!
Not sure if you're taking requests for videos, but I was curious if you could dig into (or if you know about) generating OCIO configs through python. Or OCIO configs in general?
Been a bit swamped with backlogs, i can tryyyy look at OCIO but that's something i've never generated from scratch before. Lemme see :D
Ha, the print("AArrgghh ") is definitely not something you did. In my update plugin tcl as well.
ahaahaha.. okay, glad to know :D
Never thought to use a bait node to select the top one, really interesting. Thanks Anthony!!
Anthony Tan!!! you are awesome! thank you for sharing this!! i will always like and subscribe your videos
Nice to see you back Anthony, always super interesting to hear from someone as experienced like you! Please keep the good work going, there is so much to learn from! Thank you!
GOOD JOB SIR
Great Job Keep Going Like This
Thank you so much Anthony Tan for sharing the experience TD in Nuke! if you have a course online i will support
Hey! thanks for this one and the rest of precious contents you are doing :) do you have any idea why 'nuke.knobDefault('ScanlineRender.motion_vectors_type', '0')' does not work? but if I do a normal setValue same knob same value it works, no clue about
That is indeed a good question :| I just poked and it looks like the default on the scanlinerender for motion vectors is 1.0 as well... so you're not going insane. I er.. have no idea to be honest.
What in the absolutle flip?? I did a quick dig - does nuke.knobDefault('ScanlineRender.output_motion_vectors_type', 'off') work for you? If it does, and it's not just me I will handwave a bit more. But ugh. If that works that's just.. grr. (ie. setting the default on the OUTPUT_motion_vectors_type knob)
Anthony's back!
Thanks for your new video, glad you came back.
its good to see you back..
Thanks for making this Python tutorial video...
Nice video, glad you're uploading again!
It'll be a slow burn methinks, but i'm still floating around and will be putting stuff up as i go, thanks for the support! :D
Hi anthony can you do a pyhton tutorial on how to create a shuffle breakout in nuke?
Can you describe what you mean by a shuffle breakout? (usually if in studio i'd just roll the chair over and ask to make sure i don't have the idea all wacky)
@@bondell1840 Aaaah, gotcha - lemme send out a note to the original video author and check in. No promises, but lemme see if i can do a breakdown as it were.
Your videos are really great. There are not many TD related channels that cover building tools with Python.
Thanks! Very useful content
hi Anthony Tan I have a problme with nuke project i work on it much time and when i open it i see meesage(missing close - brace) and all data was missing . please if you know how can i fix it you could help me
Ah, yeah, that one is the result of a corruption on save (or the file got mangled) - unfortunately there's not generally an automagic way to fix that, it's something to open the file up and try salvage bits of it unfortunately - unless it's super important generally it's a case of rolling back to backups :(
@@tanantish thank you Anthony
very usefull video . keep rock bro 💯
OMG YES!
I have learned a lot watching from your videos, I hope you continue the series in future :). This python training is kinda unparalled to all others available on RUclips.
Such a great series, thanks for sharing!
