Innovative Color Grading for Non-Linear Editing Software


Redefine your color grading experience

Intuitive Color Grading for Adobe Premiere Pro & After Effects, and Apple Final Cut Pro X & Motion.

Simple at first glance, ColorSynth is an elaborate pre-wired network of color processing nodes totaling more than sixty items arranged in an six-layer stack with several sub-layers.

Floating Point Precision

Regardless of the complexity of the grade, ColorSynth renders the results in floating point precision, at a constant speed.
The grading template is designed to work from a simple One Light pass to the most esoteric needs.

Innovative Color Remapping

Core to ColorSynth’s toolset is an elegantly designed collection of innovative color remapping tools called Color EQ. Color remapping tools have been around for decades; however, the mathematics usually result in unwanted color distortion artifacts that impede their usefulness and usability. ColorSynth’s Color EQ nodes have been carefully engineered to address these issues and to deliver enhanced possibilities to all users.

Color EQ nodes

The Main EQ provides Hue, Lightness, and Saturation curves with proprietary algorithms to give stunning results. The Shading EQ is a specialized tool designed to modify the Hue, Lightness and Saturation of complex conditional color qualities. The Color Mixer allows super clean RGB-based remapping of nine color bands.

Before | After

I’ve been using Colorsynth for just a few weeks and I can already see it becoming an integral part of my post workflow.

For grading directly in the NLE you can immediately see the power of its architecture, for everything from simple one light corrections to more complex and stylised grades. The concept of working in stacks is intuitive and will be familiar to anyone who has worked with a node-based grading or VFX system or even an DAW mixer.

My favourite feature is the colour EQ node. It’s super powerful and can be used for anything from very subtle adjustments to make skin tones pop to much more dramatic changes.

I can’t wait to see how Codex continue the development of the plugin over the coming months.

How can I tell if parameters for a Layer have been changed?
When parameters are changed the on/off toggle for the Layer turns blue. In a Modifier any parameters that have been changed, the parameters values will then be underlined in blue, allowing you to quickly know what has been changed on a layer.

Can I change the order of Layers or Modifiers within them?
The order of Layers/Modifiers is fixed, but designed to provide a high degree of flexibility to handle difficult grading scenarios.

What order are the Layers and Modifiers applied in?
Images cascade through the Layers from top to bottom: Input Grade, Color Selections, Unselected, Color EQ, SMH, and Output Grade. Within each Layer, the image goes through the Modifiers from top to bottom in the order shown.

Why are the colors shown in a hexagon rather than a wheel?
The color hexagon is a more accurate representation of the internal color models used.

How do I load a ColorSynth look from one machine to another?
ColorSynth looks can be saved as .cslook files and loaded from one machine to another using the Main Menu.

Can I do A/B comparisons with ColorSynth?
Yes, ColorSynth in FCPX provides an A/B Image Comparison tool, for comparing a source and reference image for matching, with a wipe and side by side comparison view.
Premiere Pro has a comparison tool built into the viewer that can be used.

How do I use the sampler tools in ColorSynth?
Click on the top bar or title of the ColorSynth effect (so it is highlighted) in order to use the sampler tools.

Where can I find my licence details if I need them?
Your licence details will be sent to you via email, and can be checked in your Profile details on the Codex website.
Once installed your licence details can be found under Main Menu of ColorSynth at the top of the effects panel. Click and select Licence.

Where can I get the latest version of ColorSynth?
You can download the latest version here

How do I copy a look between clips?
You can copy/paste the effect between clips, or save and load ColorSynth looks as .cslook files. There is also a Snapshots panel that allows quick access to up to 12 looks. Each clip stores it's own settings for the look (modifying the look on one clip will not modify another).

How do I share a look between clips?
ColorSynth is available as an FCP X Title, meaning it can span several clips on the timeline and act as a grading layer across them all.
In Premiere Pro the ColorSynth effect can be added to an Adjustment Layer to span clips.

Is ColorSynth HDR compatible?
No, version 1.2 of ColorSynth is not HDR compatible. We are working on HDR for an upcoming release.

Can I load my own LUTs into ColorSynth?
Yes, version 1.2 of ColorSynth allows loading of LUTs in the Input Grade and Output Grade layers.

Can I get a licence without an internet connection?
An internet connection is normally required to get a licence. Please email if you have problems getting a licence.

How do I un-install ColorSynth?
On Mac the folder /Library/Application Support/Codex/ColorSynth contains an uninstall script. On Windows, run the installer again and use the Uninstall option.

Do you have User Guides in other languages?
The ColorSynth User Guide is currently only available in English.

What is the difference between Selection panel and Color EQ?
Selection is for general changes to six floating presets of color that the software provides but Color EQ is for more detailed and specific adjustments.

Do I have to feed Log footage only to the ColorSynth?
No, what is powerful about ColorSynth is that it can work efficiently on footage with baked-in color and still get great results from it.

What’s exclusive about ColorSynth?
ColorSynth is using a unique underlying math which makes it extremely fast to process footages and also introduces minimum amounts of spatial artifacting even when the user has done radical adjustments to the image.

Can I use ColorSynth to edit photos?
Yes, you can use ColorSynth’s unique math to edit your photos, however your maximum resolution would be bound to what Final Cut Pro can process.

Can I export my LUTs (and looks) from ColorSynth?
You can export your looks from ColorSynth to .cslook files in case you want exchange them within different devices. Currently users cannot export LUTs but in the next few versions of ColorSynth this feature will be added.

Can I compare different versions of my grade with each other?
Yes, you can compare up to 12 different grades of the same image.

Does each layer have a fixed opacity/mix?
Each layer has a variable “mix” from 0 to 100 which gives you the ability to make subtle changes or tone down each layer’s effect on the image.
