LabelFromRead and ContactSheetAuto

LabelFromRead is a simple gizmo that displays the end of the file path from the top most read as a text overlay over the top of frame.
Useful for when you want to quickly display the filename when you are overviewing shots or sequences with a contact sheet and want to see what is what.

Basically so you don’t have to remember how to split filepaths in tcl and can easily display the image name.

Full Credit goes to Ben McEwan and his very detailed blog post about powering up your contact sheets.

The python script to change your knob defaults on the normal contactSheet node in your menu.py file is already here, posted by Ben:

This one is just for people who want to download the expressioned node and add it to their toolsets and not mess with any menu.py files.

I show this tool in a video explaining my LabelFromRead node, and I didn’t see a downloadable gizmo version on nukepedia, so figured I’d post it.


I made a brief demo of the LabelFromRead tool, along with how I use it with an automatic contactSheet node to review or compare multiple shots in a sequence.

NoiseAdvanced

NoiseAdvanced is a noise node with user friendly animation sliders, making it quick and easy to whip up some cool look dev, smoke, clouds, caustics, or whatever you like.  No more typing in those expressions everytime you want to make a subtle tweak or test some different speeds.

By default, comes in exactly like a normal noise, and is revealing all the normal noise knobs.

I’ve added an extra ‘Overscan’ slider so you can extend the noise pattern beyond the format edges and not have to mess around if you need extra noise for your image overscan.

GradMagic Tool

GradMagic is an interactive 4 point gradient tool, which can link to cornerpin nodes, and can toggle between live sampling from the plate or baking the color values of the corners.

Can be used for various tasks in prep and DMP,or if you just need a quick 4 point gradient map.

GradMagic_Properties_Screenshot.png

Quick Overview of the properties:

It’s pretty straight forward, heres some basic written steps:
1.) Set your cornerpoints manually or by pressing one of the ‘snap to’ buttons.  Or alternatively you can link or bake your cornerpoints to an existing cornerpin node (or any node with 4 “to” knobs).

2.) If you need to adjust the points once they are baked/linked/ in place, then show the adjust knobs, set the reference frame to snap the adjust points near the main points, and you can then move each cornerpoint while it still retains its animation path.

3.) You can either keep the node live, bake the corner colors on a single frame, or bake the colors over a framerange.  once baked you can adjust the cornerpoints further if you need to cover up more area.  You can adjust the ‘sample size’ at the top if you want to average more colors under each corner point.

4.) Finally you can apply a blur to the edges to help with transition, and you can select the output at the top, whether to show the gradient over the BG input, or just the gradient itself.

Hope you find it useful

Advanced Keying Template Playlist



I’ve consolidated all the Advanced Keying Videos to a single playlist on Youtube so you guys can easily view them in order and all in 1 place.  This should make it much easier to pass around to people, or to revisit them all at once.


I’ll work on getting them up on some other media sites like vimeo for those that don’t particularly like youtube.

Interview with CoreMatte.com

Matt from CoreMatte.com was kind enough to do an interview with me about my work in the VFX industry and my tutorial blog.

http://www.corematte.com/blog/interview-with-compositor-tony-lyons/

I recommend you check it out if you want to learn a bit more about me and my background in VFX as a compositor.  This was my very first interview and I am truly honored.  I also recommend checking out the rest of corematte.com for more interviews and tutorials!

Thanks Matt for taking the time to put together this interview.

Hopefully I will have more tutorials out for you guys soon.

Best,

Tony

Hey guys,

Sorry for the long overdue tutorial wrapping up this keying series. Here is the advanced keying template video, along with a flowchart and download link to the template scripts, which you can save to your toolsets for your own use in your nuke scripts.

Some of you have asked for source materials for keying practice.  I can provide you with a few free downloads so you can practice.

https://www.thefoundry.co.uk/support/user-guides/#nuke  – download the nuke keying assets

http://www.thefoundry.co.uk/products/nuke/learn1/ – scroll down to 2d compositing | Compositing Basics.  Click on the link that says Download Assets for Basic Workflows (535 MB).  Here you will find the girl and desert  BG found in this tutorial.

https://mango.blender.org/ – Tears of steal open source project.  Free 4K footage for people to download and practice.  Highly recommended.  scroll down to the blog post called ALL 4K FRAMES – NOW AVAILABLE ON XIPH.ORG.



Finally, I want to thank everyone for your continued support, views, shares, comments, and emails.  It all means a lot to me and you’ve certainly motivated me to keep going. Thank you.

As always, if there are any questions, just leave a comment or shoot me an email and I will try my best to respond.  Hopefully with this series of tutorials, and now this template, you guys will be fully equipped to handle even the toughest of keys.

Until next time!

Advanced Keying Breakdown: MERGING 3.1 – Premulting, Overs, Addmix, & CCs

Explaining Premultiplicaiton and unpremultiplication. Breakdowns of Over and Addmix, and tricks to gamma the alpha before overing. Also at the end, talking about the importance of unpremulting before color corrections (wrong and right ways to do CCs).

This tutorial uses basic colors with a transition to teach these merging techniques and the math behind them. The math and techniques are the same for complex images and alphas, but I felt it was easier to demonstrate this way. If you are bored by the beginning sections (they can be a bit basic), I’d highly recommend skipping ahead to the “gamma-ing the alpha before an over” section. I Hope this de-mystifies some complex concept of merging images, and how to use the addmix tool.

Should be 1 more tutorial left (with a possible bonus to the despill section), presenting a template script and explaining how I have put together all of these concepts we have discussed in order to bring a full key together.  This includes tips and tricks to getting around common problems in keying, despilling, and merging.  I hope to have this to you guys soon.
