PowerDirector makes it easy to add picture-in-picture effects to 360-degree videos as well. You can follow these steps to achieve this effect on your 360-degree video footage:
Open PowerDirector and import your 360-degree video into your timeline.
Select the Video Overlay (PiP Objects) Room icon on the left-hand side of the window.
Preview the built-in PiP objects, then drag your desired object below your 360-degree video in the timeline.
Drag the object horizontally across the timeline to change the timestamp where it appears in the 360-degree video.
For example, if you’d like the object to appear near the end of the footage, drag the timeline box for the object to the far right side, near the end of the timeline box for the 360-degree footage.
Customize the PiP object by adjusting the opacity, position, size, scale, rotation, and other properties using the editor.
Tip: We recommend keeping your object near the center of the preview window to avoid distortion once you convert your video back to 360 degrees. If you place your object near the top or bottom of the footage, it may not look clear in the final product.
Save your changes and export your video.
