# Accessing the Colour Corrector and the Modular Keyer from Action

By accessing the Modular 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 Action.

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

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 Modular Keyer, you do not have to click Render; 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 tools from Action:

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

3. As you work in the tool, select Context from the View box to preview the result.
4. Click Return to return to Action.

NoteWhen working with 12-bit clips in the Colour Corrector or Modular 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.

## Muting Media Effects

You can mute Keyer and Colour Corrector media effects in the Action Media menu. Muting effect media can be helpful when you want to see what your Action setup looks like without the Keyer or Colour Corrector settings, but not lose any of the settings of the muted media effect.

To mute an effect, press Alt and click the K or CC media. The check mark in the field turns black to signify the media effect is muted. To unmute the media effect, press Alt and click the field again.
