Not sure if this is usual or something has to do with my Storyline 360.
Recently, we have been asked to publish all the courses as Videos. Some slides have videos and some have narrations with animation. Publishing slides as a video (MP4) is becoming a nightmare, taking hours. It takes its usual time when I remove the videos from the slides but then I have to open Camtasia to add those videos in the slides. Too much hassle.
