How to Use Smart Trim for Your DSLR Film
There are many reasons for using Smart Trim to isolate a digital film clip, including finding an exact moment. You can let Premiere Elements do the job for you, with the Smart Trim feature. Because problematic footage is common, Smart Trim automatically handles blurred, shaky, low-quality, and low-interest sections of your video clip. Of course, with all automated functions, it’s not perfect.
There’s two ways to use this feature: automatic and manual. Consider opting for the latter. This way, you can specify the parameters for selections. Using the automatic mode, the program automatically determines sections you can trim.
To use the manual Smart Trim, do the following:
Access the Smart Trim feature.
Go to the Actions Bar and click Tools. After the panel pops up, navigate to Smart Trim. By default, Manual Smart Trim Mode is enabled. It will analyze the clip.
Adjust the feature options.
Click the Smart Trim Options button on the top right of the interface. After the dialog opens, adjust the slider to specify the options as well as setting it for automatic or manual smart trimming. Depending on the Quality and Interest values you choose, it highlights sections of the clip.
Striped patterns emphasize the areas to trim. Quality factors include blur, shaky, brightness, focus, and contrast. Interest factors include faces, camera moves, and close-ups.
Select the trim sections.
Double-click the clip to select all the area you can trim in a single clip. You can also select sections in multiple clips by dragging the marquee over the desired clips and right-clicking or Ctrl+clicking (Option+clicking on the Mac) the trim sections. You’ll see the selected trim sections are highlighted. When you select a section, all trimable sections turn into blue-striped sections.
Make a selection.
After right- or Ctrl/Option+clicking the selection, the Smart Trim options, pop up on the screen. Select the one you need for the clip or just click the striped part and delete.
The Smart Trim Options button appears on the upper-right corner of the interface. Here are brief descriptions of these options:
Trim: Trims the selected trimable section
Keep: Retains the selected trimable section
Select All: Selects all the trimable sections in the current selection
Smart Trim Options: Provides the same access as clicking the button
Other things you should know:
Smart Trim is not perfect. It often designates parts of the clip that are technically acceptable for removal. For example, panning the camera and movie subjects can confuse it.
You cannot use Interest as the only factor. Interest and Quality factors work together. Trim sections get shorter 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.
You can also trim clips using the Delete key. Just select the clip and press Delete.
Undo the previous trim action. Right-click or Ctrl+click the clip and select Undo Smart Trim.
Exit the Smart Trim mode. Click the Done button.
