I have been using that workaround in critical situations but it's not practical since, on any given day, I need to shoot 50+ separate clips, and having to reset the TC every time is a pain in the royal neck.
Sometimes you wonder what gives...such an amazing camera, the XT-3, without a basic feature you'll find in any nondescript toy camera capable of shooting video of sorts. Guess will just have to live with it, until someone at Fuji also believes it's a good idea to provide users with the actual clip duration while recording.
Happy filming!
