I have had multiple PDFs made in indesign with REALLY SIMPLE .mp4's just refuse to play. In this one, the second video plays fine, but the first will NOT play no matter what I do. I've switched the video, I've reexported it, I've deleted the contents of the page and started over, and it still just sits with that ugly loading bar whenever I open it up in acrobat to test it out. I work with video regularly, and this happened last week when I tried assembling a few videos for a project for another client. All of them loaded fine except one, and nothing I did got it to play. THIS IS UNACCEPTABLE. I've searched all over online and I can't find any way to fix it. I'm so Fing sick of adobe programs not working at their most basic fing level. I'm ****** off. My time is being wasted, and therefore my performance is being negatively impacted at my workplace. I've spent over 2 hours researching a problem that shouldn't even exist, and I still don't have a usable file containing the appropriate video content. WTF. Before&After9 doesn't play. Nothing else put in that page plays. The printing video works fine.
