How reset a clip/project in 360 STUDIO?

Not finding an option to reset a clip/project in STUDIO.

I zoomed in and the quality of the video got very blurry.
Closed and reopend file and it's the same.

Something happened to this file in editing so how can I reset?

Also, I notice quality gets blurrier as I zoom in on a scene.
Is there a setting in the X2/X3 camera I should be using to offset this from happening?
Or is it just a limitation of the camera?

Thanks!
