This new version is less user-friendly than Studio15 (or 9 to 15 who had all versions). Not as easy to select a part of video (in 15 two handles are used to select a part of the video). To adjust the sound it is more complex. Remember to use the general curve to reduce noise if you add a music and want to keep a few comments. For manipulants people equalizers her but it is more efficient for a person to average it becomes complex. I kept both versions on my PC, and will continue to use them.
