Today, I gave the 6.3.2 version a much better test than I had before. I took an hour video that had several places I wanted to remove, and allowed the “Auto” scene changes to be located. That divided the original file into 2,167 parts. I noticed that the thumbnail view was one off from what was played, which made it difficult to select which scenes I wanted to Delete. When I did finish, I let Auto-Remaker recombine the file. When I played the result video, nearly every phrase is repeated in rapid succession. It was intolerable to watch.
I mention the 6.3.2 version because I do not have enough time to test the 6.4.3 version the same way. Has anyone seen the same problem in either of these two releases?
