Video / Audio clips will not play in Full Screen Mode

Hi
 
I've produced a small brochure in InDesign CS4 which contains a small video and audio clip. The completed project is meant to be delivered as a PDF which should open in Full Screen Mode. The video and audio files play perfectly in Normal Mode (albeit that I have to click the 'Trust This Document...' option.
However, neither file will play when the PDF opens in Full Screen Mode unless the user exits Full Screen Mode, check the 'Trust This Document .. ' and then returns to Full Screen Mode. Makes a bit of a mockery of digital document presentation.
 
I am using Acrobat 9 Professional. Anyone any idea if there is a fix for this. All suggestions gladly recieved.
 
Regards
 
George

That's the price you pay for using legacy media objects (which is the type of video/audio annotation that InDesign CS4 inserts).

If you remove the rich media elements from the InDesign file (or turn them off for export) and add them using Acrobat's Video and Audio tools, they will be placed in native Flash format and won't trigger a trust message bar - hence they'll work fine in FS mode.

Hi UVSAR

Thanks for that. Unfortunately for this project (and the rest in the series) all content including audio and video is placed in InDesign. That idea being that designers can create all of their work in ID and then export it to PDF - the intention being that they do not have to work directly with Acrobat.

Since my first post I wondered about attaching a small piece of JavaScript that would alert the user to the need to switch back to Normal Mode.

I don't know how to write JS so maybe someone can help me with this (if I'm not pushing my luck).

Thanks again

Adobe advises that legacy media within PDF files is avoided at all costs, and playback is disabled by default in Acrobat and Reader 9 and above, with authoring of legacy media removed entirely from Acrobat X. There are significant security issues with the way legacy media operates, and while your document may be trustworthy, asking users to trust any file from an external source is not the best idea and is often something blocked by enterprise IT departments. It also relies on external playback applications, so video is notoriously unreliable on Mac platforms.

InDesign up to the current version does not use Acrobat or Distiller to create PDFs - it has an internal copy of the PDF Library engine, which is only partially implemented and so cannot support features such as native media, scripting, etc. I can't comment on when or if that will change.
