Question
mp4 appears as black box in interactive PDF exported from InDesign
I have placed an MP4 in InDesign and exported as an interactive PDF. When previewing in SWF preview it all looks fine, but within Adobe Acrobat it appears as a black box. It was working earlier but now this is happening and no idea why. I have tried restarting, saving as new docs but to no avail. I am saving the video out from After Effects as H.264, I don't know if something is wrong that side of it. Any ideas? Thanks!
