Ops 7–28 • Keying Vision Operator’s Manual (v12.0 MD)
Pattern Mask
The Pattern Mask uses a pattern to mask the key, rather than a box. The pattern mask can be
adjusted for size, location, rotation, and multiplication.
Use the following procedure to apply a pattern mask to a key:
1. Press the MASK button on the Keyers Module.
2. Toggle Mask on the Mask Setup Menu to On to apply the mask to the selected Keyer.
3. Toggle Force on the Box Mask Menu to On to force the masked area of the image on
screen.
4. Toggle Invert on the Box Mask Menu to On to reverse the mask. The portion of the
image that was masked out is now visible, and the portion that was visible is masked.
5. Press Pattern Mask on the Mask Setup Menu.
Pattern Mask Selection Menu
6. Select the pattern you want to use on the Pattern Mask Selection Menu. You can also
use the keypad on the memory module to select the pattern button number (#xx).
7. Use the positioner to adjust the position and size of the mask.
8. Press Modify Pattern on the Pattern Mask Selection Menu.
Pattern Mask Parameters Menu
9. Use the Softness knob on the Pattern Mask Parameters Menu to adjust the softness
of the edge of the pattern.
10. Adjust the pattern parameters (Rotation, H-Mult, V-Mult, and Aspect) as required.
Refer to the section “Pattern Parameters” on page Ops 6-5 for more information.
This completes the procedure for applying a pattern mask to a key.
