The Media Matte visual effect is a simplified way to add track mattes or “masking” to your videos.
When you apply the Media Matte effect to media on a track on the timeline, sections of the media on the tracks directly below display or are hidden by transparency and brightness properties of the media on the track above.
Camtasia supports the following transparent media file formats: .mp4, .mov, .gif, .png, and .bmp.
Note: Apply a Media Matte with Alpha mode to a track that contains media with transparent pixels or media that does not cover the entire canvas such as still images and annotations.
Apply a Media Matte Effect
Apply a Media Matte effect to compatible media on a track.
Click the Visual Effects tab.
Drag the Media Matte effect onto an image or clip on the timeline.
Drag the Intensity slider to adjust the visibility of the selected mode.
Set the amount of time you want the effect to Ease In or Ease Out during playback. (Optional)
Note: Create complex track matte animations and transitions by grouping media. See How to Use Group Tabs.
Media Matte Modes
There are four modes available in the Properties panel after applying the Media Matte effect:
Alpha: Media on the tracks below is not visible through the transparent pixels and visible through the opaque pixels on the track above.
Maximum Intensity = 100% visible
Minimum Intensity = 0% visible
Alpha Invert: Media on the tracks below is visible through the transparent pixels and not visible through opaque pixels on the track above.
Maximum Intensity = 0% visible
Minimum Intensity = 100% visible
Luminosity: Intensity of the media brightness determines the level of pixel visibility and transparency between tracks.
Maximum Intensity = 100% visible
Minimum Intensity = 0% visible
Luminosity Invert: Intensity of the media brightness determines the level of pixel visibility and transparency between tracks.
Maximum Intensity = 0% visible
Minimum Intensity = 100% visible
Add Track Mattes Manually
To manually enable track mattes on the Camtasia timeline, right-click (Windows) or Control+click (Mac) the icon on a track and select a Track Matte Mode option: Alpha, Alpha Invert, Luminosity, or Luminosity Invert. See Media Matte Modes.
