I am importing Edge .oam files in to Indesign on black backgrounds. The animations work fine but in Content Viewer they begin with a split second white flash in the boxes they've been placed, which is distracting. The Poster .png is a blank black image as I want to reveal the animations on page entry. How can i get these to run without the initial white flash?
Problem solved! Make sure the stage in Edge is set to transparent using the alpha slider and the poster image on export is made transparent in the export settings.
Also, make sure the pic box containing the .oam file in Indesign is checked 'Transparent' in the Folio Overlays panel.
Thanks for sharing solution, it will help others.
