USING ADOBE PREMIERE PRO 382 Effects and transitions Difference Matte effect The Difference Matte effect creates transparency by comparing a source clip with a difference clip, and then keying out pixels in the source image that match both the position and color in the difference image. Typically, it's used to key out a static background behind a moving object, which is then placed on a different background. Often the difference clip is simply a frame of background footage (before the moving object has entered the scene). For this reason, the Difference Matte effect is best used for scenes that have been shot with a stationary camera and an unmoving background. For more information on using the Difference Matte effect, watch the online training video on the Total Training website. A B C D Difference Matte effect A. Original image B. Background image C. Image on second track D. Final composite image Replace a static background with Difference Matte The Difference Matte creates transparency by comparing a specified still image with a specified clip and then eliminating areas in the clip that match those in the image. This key can be used to create special effects. Depending on the clip, it's possible to use Difference Matte to key out a static background and replace it with another still or moving image. You can create the matte by saving a frame from a clip that shows the static background before the moving object enters the scene. For best results, neither the camera nor anything in the background should move. The following Difference Matte settings are adjusted in the Effect Controls panel: View Specifies whether the Program Monitor shows the Final Output, Source Only, or Matte Only. Difference Layer Specifies the track to be used as the matte. If Layer Sizes Differ Specifies whether to center the foreground image or stretch it to fit. Matching Tolerance Specifies the degree to which the matte must match the foreground in order to be keyed. Matching Softness Specifies the degree of softness at the edges of the matte. Note: The RGB Difference Key uses color to define transparency much as the Difference Matte uses a still image. Blur Before Difference Specifies the degree of blur added to the matte. 1 Find a frame of your foreground clip that consists only of the static background. You will use this frame as a matte. Save this frame as an image file. It will appear in the Project panel. 2 Drag the matte frame from the Project panel to a video track in a Timeline panel. 3 Drag the clip you want to use as the background to a track in a Timeline panel above the matte frame. 4 Place the video clip you wish to use in the foreground on a track in a Timeline panel above the background clip. 5 (Optional) If you're animating the Difference Matte over time, make sure that the current-time indicator is in the position you want. Click the Toggle Animation icons for the settings you adjust. 6 In the Effects panel, expand the Video Effects bin and then the Keying bin. 7 Drag the Difference Matte effect onto the foreground video clip. 8 In the Effect Controls panel, click the triangle next to Difference Matte to expose its controls.

Difference Matte effect

The Difference Matte effect creates transparency by comparing a source clip with a difference clip, and then keying out

pixels in the source image that match both the position and color in the difference image. Typically, it’s used to key out

a static background behind a moving object, which is then placed on a different background. Often the difference clip

is simply a frame of background footage (before the moving object has entered the scene). For this reason, the

Difference Matte effect is best used for scenes that have been shot with a stationary camera and an unmoving

background. For more information on using the Difference Matte effect, watch the

online training video

on the Total

Training website.

Replace a static background with Difference Matte

The Difference Matte creates transparency by comparing a specified still image with a specified clip and then

eliminating areas in the clip that match those in the image. This key can be used to create special effects. Depending

on the clip, it’s possible to use Difference Matte to key out a static background and replace it with another still or

moving image.

You can create the matte by saving a frame from a clip that shows the static background before the moving object

enters the scene. For best results, neither the camera nor anything in the background should move.

The following Difference Matte settings are adjusted in the Effect Controls panel:

View

Specifies whether the Program Monitor shows the Final Output, Source Only, or Matte Only.

Difference Layer

Specifies the track to be used as the matte.

If Layer Sizes Differ

Specifies whether to center the foreground image or stretch it to fit.

Matching Tolerance

Specifies the degree to which the matte must match the foreground in order to be keyed.

Matching Softness

Specifies the degree of softness at the edges of the matte.

Note:

The RGB Difference Key uses color to define transparency much as the Difference Matte uses a still image.

Blur Before Difference

Specifies the degree of blur added to the matte.

Find a frame of your foreground clip that consists only of the static background. You will use this frame as a matte.

Save this frame as an image file. It will appear in the Project panel.

Drag the matte frame from the Project panel to a video track in a Timeline panel.

Drag the clip you want to use as the background to a track in a Timeline panel above the matte frame.

Place the video clip you wish to use in the foreground on a track in a Timeline panel above the background clip.

(Optional) If you’re animating the Difference Matte over time, make sure that the current-time indicator is in the

position you want. Click the Toggle Animation icons

for the settings you adjust.

In the Effects panel, expand the Video Effects bin and then the Keying bin.

Drag the Difference Matte effect onto the foreground video clip.

In the Effect Controls panel, click the triangle next to Difference Matte to expose its controls.
