It is similar to the Blue Screen Key and Green Screen Key, but it also lets you blend two clips. In addition, it helps reduce fringing around the edges of opaque objects. Use the Non Red Key to key out green screens when you need to control blending, or when the Blue Screen Key or Green Screen Key don't produce satisfactory results.</p><p class="paragraph">Adjust the following settings as needed:</p><p class="run-inhead">Threshold</p><p class="paragraph">Drag to the left until the blue or green screen becomes transparent. </p><p class="run-inhead">Cutoff</p><p class="paragraph">Drag to the right until the opaque area reaches a satisfactory level. </p><p class="run-inhead">Defringing</p><p class="paragraph">Removes residual green or blue screen color from the edges of the opaque areas of a clip. Choose None to disable defringing. Choose Green or Blue to remove a residual edge from green-screen or blue-screen footage, respectively.</p><p class="run-inhead">Smoothing</p><p class="paragraph">Specifies the amount of anti-aliasing (softening) that Adobe Premiere Elements applies to the boundary between transparent and opaque regions. Choose None to produce sharp edges with no anti-aliasing. This option is useful when you want to preserve sharp lines, such as those in titles. Choose Low or High to produce different amounts of smoothing.</p><p class="run-inhead">Mask Only</p><p class="paragraph">Displays only the clip's alpha channel, as modified by the key settings.</p></ol><hr /><div class="breadcrumbs"><a href="1_7_18_3.html" title="About the Blue Screen Key and Green Screen Key effect">Previous</a> | <a href="1_7_18_5.html" title="Using the Track Matte Key effect">Next</a> | <a href="#top">Top</a> | <a href="1_7_0_0.html">Applying Effects and Transitions</a> > <a href="1_7_18_0.html">About keying effects</a></div></td></tr></table>
