i made a menu in after effects and it has a video bit before the button is shown
whenever i create the button and i preview my menu it just goes to the part where the button would be created and skips all of the video at the beginning how do i get around that?
How do you mean "before the button is shown"? I would need to know the exact setup of the menu. Do you have a video set as the background, partway through which a 'button' appears on the video? Or do you have a video file that is set to play before the menu? Have you modified the loop point of the menu?
