return to the Timeline.
To save a mask

Note: If you invert the mask, the preview area does not show the inverted mask—it
displays when you return to the Timeline.

3 Click the Save As button at the bottom of the dialog box, and choose a name for the
mask.
If you want to link the mask to the original clip, mark the Link mask to source clip check

or Video Mask from the Type drop-list.
4 Click the Add mask item(s) button to the right of the mask preview area, and browse
to a saved mask file (.uisx format for a video mask, .png for a still mask).
The mask is added to the preview area.
You can remove files from the video masks list by clicking the thumbnail for the mask,
and clicking the Remove mask item button .
You can create a folder for masks in the default user content folder: ...Documents/
Corel VideoStudio Pro/22.0/.
Track transparency
You can use the Track Transparency mode to precisely control the transparency of a track.
Key frames let you vary track transparency to achieve the effect you want. For example, you
can adjust the transparency of a track to create a superimposed effect (where the underlying
track shows through) or to create a custom fade in and fade out effect.
