I am assuming you are using an iPad or similar? with iMovie on a desktop (iMac) the icon you describe is 'Export' not 'Save'. 'Export' is totally different from 'Saving' or 'Saving As', on most software you can 'Save' the document and 'Save As' by a different name, thereby increment the document in case you want to go back a stage. The 'Save' you describe is actually 'Export', which compiles the movie in one of several optional formats, probably defaulting to MP4. You can't go back to an MP4 document and edit it, at least not without re-importing it, which I think would need additional software. I don't think iMovie can edit an MP4 video, I have tried in the past.
It exports (from iPad ) as a .movmobile file that can be reopened as a copy in iMovie for further editing without any compression loss. It than can be reexported as that unique copy for future use on the native machine or saved as a .mov file (compressed) for other uses.
Jan's Panasonic shoots video in .mp4 and I have no problems opening them in iMovie (on the iPad). In fact the hedgehog clips I have been doing were taken on her camera and they are mp4 (just checked).
I am not sure if Nikon captures video in a different format to the Panasonic?
