Accessing the Colour Corrector and the Keyer from Action
 
 
 

By accessing the Keyer and the Colour Corrector directly from Action, you can key any media or colour correct any front, matte, or back clip without having to exit to the Desktop.

When you enter the Colour Corrector or Keyer from Action, you can view the result of your colour correction or key as it would appear in Action using the Context button. The Context view is interactive; as you make changes, the Action result is updated in the image window.

As you use more media in Action, interactivity in the Colour Corrector and Keyer may be slower than when you access the modules exclusively from the Desktop. However, accessing these modules through Action is more efficient for checking your changes against the other Action media.

Use Result view while keying or colour correcting. In this way, the number of Action media has no impact on system performance. You can tweak the keying and colour correction setup using Context view.

While you work in the Colour Corrector or Keyer, you do not have to click Process; the modifications are automatically applied to the media in Action. If you enter the Colour Corrector from Action, scrub the timebar to view the Result.

NoteWhen loading Action setups that contain CC or Keyer effects from a previous version, you may experience a slight loss of quality when viewing proxies. To avoid this loss of quality, select Proxy Full from the Action Setup menu.

To access other modules from Action:

  1. In Action, click Media.
  2. Double-click the corresponding field for your chosen media and module. For example, to colour correct the matte clip, double-click the matte CC field.

    TipYou can set the default keyer to Keyer or Modular Keyer in the Action Setup menu, or press Ctrl and double-click the Keyer field to enter the non-default keyer (Keyer or Modular Keyer).
  3. As you work in the module, click Context to preview the result.
  4. Click Exit to return to Action.
NoteWhen working with 12-bit clips in the Colour Corrector, Modular Keyer, or Keyer, you create a new setup at 12 bits. If you return to Action and work at proxy resolution, the setups are scaled to 8 bits (along with the proxies) and 4 bits of colour are lost. However, if you switch to proxies once you return to Action, a copy of the 12-bit setup is stored and restored when you are ready to process at full resolution.
