Chromanator Tutorials: Chromanator Misc

Using presets

With the number of tools at your disposal in Chromanator, it can sometimes take a while to set everything up how you want it. In some projects you may have several objects which all need to have similar settings, or you may want to transfer one object's settings to a different project entirely.

To speed up the process you can simply use the preset feature, which allows you to save all the details of an object and apply them to another object.

For this example I'll use these three greenscreen shots:

As you can see, they all share similar setups and problems, including poorly lit greenscreens. The Colour Difference key is not particularly effective by itself, leaving a very dirty and unfinished key:

However, if I first apply a fairly extreme case of Super Contrast using the Key Grade toolset, the green becomes clearer and more pronounced:

The Colour Difference key now has better information to lock onto, making the key much cleaner.

  • When dealing with difficult keys with sub-standard colour information, the Box Blur Alpha tool helps to smooth the edges of the key:
  • The colours of the greenscreen clip will be normal when the clip is rendered, as the Key Grade tools only affect the alpha channel.

Finally, the Spill Suppression tool takes care of the green fringing.

However, I don't want to have to perform all those steps for each clip. Instead, I can save a preset by clicking the button to the right of the Tool Inspector title bar.

The Save Preset dialog allows you to enter a name and description for the preset as well select which toolsets you wish to save. In this case we want to save the Grade, Key->Grade and Key->Key toolsets.

The animation toolset is always selected by default because an object always has animation keyframes – even if it is just a single keyframe to keep it in one place.

This preset is now available to every object and can be accessed by choosing the Load Preset option from the same menu.

  • Presets can be accessed even when working in a different project.

The Load Preset dialogue displays all the available presets along with their accompanying details:

Simply click Load to apply the preset. The tools can then be manipulated normally from within the object.

If you always remember the preset function it can save you a lot of time when working with the different toolsets and creating animation.
