User Manual

By default, these ganged sliders move together as one, resulting in each color channel of the
image being equally affected. A small white button to the left of each control’s name lets you
ungang these sliders, in order to apply degrees of adjustment to individual color channels.
Blur
The default mode, Blur lets you apply an exceptionally high-quality Gaussian blur, or another
equally high-quality sharpening operation to your image. This mode of operation has the
simplest controls.
Two sets of linked parameters let you adjust the extent and directionality of blur or sharpening.
Which is applied depends on the direction in which you adjust the Radius control.
Blur Radius controls are ganged by default, but can be unganged
 Radius: This is the primary control for adding blur or sharpening. The default value of
0.50 results in no effect being applied to the image. Raising the radius slider increases
blur, while lowering the radius increases sharpness, with a minimum value of 0.00
providing maximum sharpness.
TIP: If you raise the Radius slider all the way to 1.00 and the image isn’t
blurred enough, add another node and use it to add another blur operation.
You can also use the scroll wheel on your mouse while hovering over one of
the bars to increase the radius.
 H/V Ratio: Lets you add directionality to the current operation. At the default value of
0.50, the image is affected in both the horizontal and vertical directions equally. Raising
H/V Ratio makes the effect increasingly directional along the horizontal axis, while
lowering makes the effect increasingly directional along the vertical axis.
To adjust the Blur controls using the DaVinci control panel:
1 Press the VECTORS button on the T-bar panel, or the VECTORS soft key on the
Trackball’s main page.
2 Use the BLUR AMOUNT and H/V RATIO knobs to add either blur or sharpening.
3 When you’re finished, press the PRIMARIES soft key to return to the Center panel’s
main page.
