Auto movie mode is clunky
So its ok if you just using automatic movie mode. It makes a slightly interesting movie clip. But if you try to find tune the edit, it changes all the clip points after editing just that one. If you make that one clip five seconds longer, it will change all the the other clips after that to a 30 seconds. So then you have to edit all the other clips that had previously been automatically generated in automatic movie mode. And trying to find tune those edits are very difficult. Sometimes it just doesnt do what you want. And each time you edit the next clip the next batch of automatically generated points are changed again.
