How do you want to mix a 360° video with a non-360° video? As you might know, a 360° video is a kind of projection of a video in the inner surface of a sphere. You as a viewer are in the center of that sphere. You can look in any direction, you will see the projected video clip. If you have a non-360° video, you have to decide, how to project it on the inner surface of the same sphere.
The most popular way is to project it over the view-angle of that clip on the inner surface. If you look in the direction of the projected video, you see it. If you look in an other direction, you will not see it. Thats the way 360° works.
But if you are in the center of the sphere, you cannot leave it for the same video file, so having a 360° video and leaving the 360° video mode and display a "normal" video without the 360° controls by using just one video file is not possible.
Thre are not many editors, that can edit a 360° clip. One of them is PowerDirector, I think, since version 15, even better in version 16, but PowerDirector is not able to stitch the video clips. You still need the Gear360 ActionDirector for that.
I hope, I understood your question. And it does really no matter, which editor you use.
