A selection mask lets you select only the pixels in a video clip that you want to adjust. This allows you to select and adjust static objects in the video clip.

|
Note: the selection mask is ideal for adjusting areas of video in videos clips where the camera or objects in the area are motionless. If the camera is moving or objects move in the frame, try using a motion tracking mask. See Using a Motion Tracking Mask for more information.

Creating a Selection Mask
To create a selection mask and use it to make adjustments, do this:
1. | Click to open the selection mask controls. |
2. | Use your mouse to manually select the area of the video frame you want to adjust. You do this by clicking around the outline of the area until an enclosed section is selected. |



|
Note: to create horizontal or vertical lines using straight line control, just hold down the Shift key on your keyboard when adding node points.
|


|
Note: you can adjust the shape of the selection mask by clicking and dragging the nodes. Click a node to select it, and then press the Delete key on your keyboard to delete it. To add a new node, just hover your mouse over the line edge and click to add the required node.
|
3. | Use the Feather slider to set the transition level between the area being selected and the pixels around the area. This slider is not enabled until a masked area has been defined on the video frame. |

|
Note: CyberLink ColorDirector displays a mask color marker on the area you select. Right click on the mask color marker for more selection mask options.
|
4. | Make the required adjustments to the selected part of the video frame using the regional adjustment options. See Regional Adjustment Options for a detailed description of all the available adjustments you can make. |

|
Note: if required, click the button to invert the selected pixels. When selected, CyberLink ColorDirector will apply the adjustments to areas that were not selected. Click it again to revert the adjustments back to the pixels selected originally.
|
Adjusting Mask Position and Shape
If the selection mask you created appears off at any point during the duration of the video clip, you can easily adjust its position or shape.

|
Note: when you adjust the position or shape of a selection mask, CyberLink ColorDirector automatically adds a keyframe to the keyframe settings timeline to mark the change. See Utilizing Keyframes for more information on keyframes.
|
To adjust the selection mask position/shape, pause the video clip playback at the point when you want to make the adjustment and then do any of the following:
• | click on a mask node to select it and then drag it to a new position. |
• | click on a mask node to select it, and then press the Delete key on your keyboard to delete it, if required. |
• | to add a new mask node, just hover your mouse over the line edge and click to add the required node. |
• | click on the mask color label and then drag the entire mask to a new position. |
• | right click on the mask color label for more options, including selecting all nodes, deleting the mask, resetting the adjustments, and more. |
Using Multiple Selection Masks
You can make up to five different selected adjustments on a video. When you select areas of the video and modify the adjustment options, a mask is auto created and labeled by color.
The mask label is visible in the Mask drop-down at the top of the selection mask tab.

To create a new adjustment mask, do this:
1. | Select New from the Mask drop-down to create a new mask. |

2. | Use your mouse to manually select the area of the video frame you want to adjust, and then use the sliders to set the adjustments as required for the second adjustment. |
3. | CyberLink ColorDirector labels the mask with another color in the Mask drop-down. |

4. | CyberLink ColorDirector marks each mask on the video with the color label. |

5. | Click the color label to quickly select the mask, and view the selected areas (pixels) of the video where each of the adjustments was applied. |
