Steps
1Paint the mask with the brush
Use the first two Manual Tools to add to the mask and erase from it, and Brush Size to set the stroke width. The second pair is the smart brush: it takes a whole region from one stroke.
On a still image you also get the Auto object selection tool. It does not appear on video clips.
2Trace the mask with the polygon tool
Click around the area to drop nodes and join the last back to the first. Click a node to get curve handles on either side of it. Click the mask edge to add a node there.
Drag the Feather Radius slider on the left to feather the edge, and check Invert mask below it to invert the mask. Click + at the right end of the Polygon Mask heading to add another polygon mask on the same clip.
3Or use text as the shape
Choose Text and click the preview to type. Use the left panel to set the font, size, spacing, and position, and click Insert title at the top right to add a second block.
To delete one, click its edge first. The outline turns from dashed to solid, and only then does Delete remove it.
4Click OK to apply the mask
Click OK at the lower right of Advanced Mask Editing, and the preview plays the footage only inside the mask.
We tested these steps in PowerDirector 365 version 24.0.7 on Windows.
