Unfortunately, when you add a media file (video, for example) into a new preset or into a layer it starts playing immediately, even if you just want to have it ready (not playing) for an upcoming moment. The only thing you can do is pause it but no rewind is available. If you click “play” after “pause” it obviously continues at the same point where it was paused. If you click on the media file under “Video Sources” it’ll rewind to the beginning but start playing immediately again. Can I suggest that media files like videos, for example, not play until the user clicks on “play”? Can a slide bar be added where the user can move forward or rewind the video? Better yet, can a control bar be added with pause, play, back, and forward buttons?
