How to Use The Masking Effect

The feature allows you to insert the mask in any shape, such as a rectangle, circle, or triangle. You can also import any shapes you like if you can't find them in the presets library. You can also adjust the mask placement, width, height, and feather effect.

Without further ado, let's see the detailed step-by-step guide for this effect.

a. Preparation

You will need at least three shots of the same frame to get the shadow effect to work. The first is the main video, the second is the shadow clip, and the last would be a clip portraying just a plain background.

Make sure that your camera stays at the same point and angle. You can use a tripod for assurance.

Take the first main video and don't forget to mark the positioning of the object for the next take. Then, you can shoot the shadow clip following the marking of the object to match its position in the main clip.

Finally, shoot the final clip without the object on the frame.

b. Steps to add the shadow effect to your videos using Masking

Step 1: Place the main clip on the timeline and find the start of the segment that you want to use. Press M on the keyboard to set a marker.

Step 2: Place the shadow clip on top of the main clip on the timeline. Trim and adjust until the shadow clip ends right at the marker of the main clip.

Step 3: Move the play head to the start of the shadow clip. Trim the main clip right on that mark so both clips have the same start by clicking the scissor icon and deleting the unused part.

Step 4: Double-click the shadow clip. OpenSettings > Mask Section > Rectangle to apply the mask. Adjust the blur strength to smooth out the edge.

Step 5: Play the result to see if there's any part you need to block out. When you find them, repeat steps 1 to 4 but with the background clip. Try to conceal all things you need to hide using the masks. Make sure that you get the timings right.
