An option (and possibly the only other option) would be to put all 22 clips on a single time line. It will automatically create a chapter for each video clip (I believe) as you insert them into the single time line. From there you will be able to freely browse back and forth as you desire. There are some downsides to this, but I’m not really aware of them all as I’ve only got about maybe ten hours or so of encore experience under my belt and it’s all been with a single project. One of the downsides involves the “Override” option either not working properly or at all. The override option still confuses me a little, and the fact that every single item that has an “End Action” option also has an “Override” option makes the use of the “Override” option even more unclear to me.
I hope this will be of some help, even if just a little, but someone here with more experience can likely offer a much better solution. Good luck 🙂
