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 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 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 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.


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 Breakdown: ALPHA 1.3 Channel Math / Combining Keys

0:00 Intro, RGB channels
6:00 Luminance
8:37 Adding all channels
11:39 Adobe After Effects Matte technique
16:21 Channel math summary
20:02 Combining Mattes with Keymix
23:20 Isolated mask Post-Grading

In this video I break down the basics and fundamentals of what keying is and how you can make keys from individual channels.  I also talk about using keymix to combine different keys, and how to isolate only certain areas of the key to adjust with a post- grade.

Here is the Channel Control tool I showed in my tutorial:

My next video should wrap up the alpha section, stay tuned.

HighPass Gizmo: tutorial + download


I’m going to show you the highpass tool I developed in nuke.

I got the idea after reading Digital Compositing for Film and Video with Steve Wright.
gives you the difference between a blurred input and the original input. making small details quite noticeable.

The 2 main uses are:
1.) to Aid 2d tracking
2.) to apply a different type of sharpen filter to an image.

Here is the link to download the gizmo.  Thanks!
