Apply Sharp and Smooth modes in Object Masking

Terakhir dikemas kini pada 15 Apr 2026

Adjust mask edge quality to match your footage and creative needs in Adobe Premiere.

Object Masking in Premiere offers edge-refinement controls that help you achieve precise isolation of subjects in your footage.

Edge quality modes control how Object Masking defines the boundary between your selected subject and the background. Use sharp mode for high-contrast subjects or hard edges, and smooth mode for subjects with softer transitions, such as hair or translucent materials. These allow you to handle complex masking scenarios more effectively without compromising quality.

The first time you use Object Masking, Premiere automatically downloads the required AI models. While models are downloading, Object Masking will be temporarily unavailable. You can track download progress in the Progress panel.

Adjust edge quality mode

Select the Object Mask Tool from the toolbar.

Before creating the mask, choose between Sharp or Smooth mode from the quality options.

Choose Smooth or Sharp to control edge softness for the object mask in the Program Monitor.

Hover over the Program Monitor to see highlighted objects, then select the subject you want to isolate.

With your object selected, open the Effect Controls panel.

Find an effect in the Effect panel, such as Gaussian Blur, drop the effect on the clip in the timeline, and the mask will automatically be applied to the effect.

Petua:

To achieve the best Smooth mask quality, select Smooth mode for subjects with fine details such as hair, fur, or intricate patterns.

Use Sharp mode for objects with clear, defined edges. Start masking from a frame where the object is most prominently visible.

Test both modes to see which works better for your specific footage.

Viewing mask quality

Once you've created an Object Mask, you can view which quality mode was applied:

Open the Effect Controls panel.

Locate the mask in the effects stack, and under Mask Quality, you'll see either Sharp or Smooth displayed, indicating which mode is active for that mask.

Nota:

You can switch between Sharp and Smooth modes after creating a mask. However, switching mask quality modes will clear the existing mask, requiring you to recreate it.
