As a result, it cuts in very short arcs with long-ish pauses or re-alignments between them. Ultimately, the quality of the cut is OK, but it takes 3-4 times as long, for all these restarts. It’s a little hard to describe; I tried uploading a video, but could not, as a new user. I’ve read a bunch about stutter on this forum and others. I don’t think t…
