So far this has been working really well but ran into a couple of issues.
Noticed that it performs MUCH faster when you are only running it on a single continuius clip, vs multples. E.g. if you have already made a few cuts and want to edit down everything a bit more granularly... choosing one clip that may have a few different scenes in it performs well, vs selecting multiples, it goes slower and in a couple instances got hung up at the 100% progress and needed to "Cancel".
Also, I noticed that when it fails, it doesn't give you a message "Unable to detect scenes" or something a bit more responsive. I have a :30 clip that has ~10 different images in it, each one does a simple slide or crossfade transition. The clip goes to process, however at the end of about 10 seconds of grinding away, nothing happens - and no alert.
