Hi , i'm new to this. I exported a video as a blu ray h.264 file for my menu, I then imported it to encore as an asset. imported a blank menu. Dragged the motion whip for the blank menu to my asset video file. I then wrote over top of the menu in encore with the text tool, converted the text to buttons, linked the buttons to my timeline. In preview mode, the motion menu doesnt play. Its remains stationary on the first frame. Any ideas? what am i doing wrong?
