question 26 (1 point)
which shape tool can you use to draw an opacity mask?
a ellipse or pen tool
b keyframe brush
c polygon selection
d crop tool

Explanation:

• Question 24: An opacity mask is used to hide parts of a clip so only selected areas are visible. Cropping (b) changes the visible frame size, adding brightness (c) affects color intensity, and changing playback speed (d) alters how fast the clip plays.
• Question 25: In video editing software (like Adobe Premiere Pro), the Effect Controls panel is where you create an opacity mask. The Lumetri Color panel (a) is for color grading, the Project panel (b) is for asset management, and the Audio Mixer (c) is for audio adjustments.
• Question 26: The Ellipse or Pen tool can be used to draw an opacity mask. A keyframe brush (b) is for setting keyframes, polygon selection (c) is for selecting areas (not typically for drawing masks in the context of opacity masks in video editing software), and the crop tool (d) is for cropping (not for drawing masks).

Answer:

• Question 24: A. Hides parts of a clip so only selected areas are visible
• Question 25: D. In the Effect Controls panel
• Question 26: A. Ellipse or Pen tool
