How was the sample created?

I cut a clip from a larger sample with video (which I was asked not to share in its entirety) using ffmpeg -i in.mkv -c copy -map 0:a out.mkv. I'm not sure where the original sample originated; it's a home video from a camcorder, but I don't know if it was reencoded or remuxed at some point.
