I've added fps as you suggested early, now I'm looking into a way for having some options to set, but they should be optional (for advanced use only).
something like an advanced checkbox on first window perhaps... not really sure how to change platypus default window to do that. so far i'm not getting "warm" with platypus and cocoadialog. as far as i see you can only trigger dialog popup (i might be wrong) which is not great to use.
i think the app (the ideal app) should be something like:
-be as easy as possible
-give as much control over the image (raw->img process) as possible (if desired, advanced option). Since those settings gets "backed" into resulting img seq or video.
-be suitable for batch process
btw, did my app work on your computer?
i don't like on mine:
-no drag drop on app (in file selection does work)
-not nice ui (but hey, a ui ;-)
-no feedback about what it is doing ( while raw2dng and dcraw-video)
