Smart Trim options
Smart trimming uses quality factors such as brightness, blur, shaky, and contrast and interest factors such as face, motion, and dialog as criteria to
trim the clips. You can set the levels of quality and interest before trimming the clips.
Quality Level
Enables you to specify the levels of quality factors that Premiere Elements uses to determine the trimmable sections. The quality factors include
blur, shaky, brightness, focus, and contrast. If you move the slider to the extreme right, all low-quality sections are highlighted as trimmable
sections. As you move the slider toward the left, the trimmable sections reduce. If you move the slider to the extreme left, only low-quality sections
are highlighted for trimming.
Interest Level
Enables you to specify the levels of interest that Premiere Elements uses to determine the trimmable sections in a clip. The interest factors include
faces, dialog, close up, camera moves like pan and zoom, and the number of people in a group.
note: You cannot use Interest as the only factor to determine the trimmable section. Interest and Quality factors work together. Trim sections
reduce when you move the slider from right to left. A clip that is low in quality or interest gets trimmed. A clip that is high in quality or interest
doesn’t get trimmed.
